A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as (...) with sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

This review considers a number of recent theories on the neural basis of consciousness, with particular attention to the theories of Bogen, Crick, Llinás, Newman, and Changeux. These theories allot different roles to various key brain areas, in particular the reticular and intralaminar nuclei of the thalamus and the cortex. Crick's hypothesis is that awareness is a function of reverberating corticothalamic loops and that the spotlight ofintramodalattention is controlled by the reticular nucleus of the thalamus. He also proposed different mechanisms (...) for attention and intention . The current review presents a new hypothesis, based on elements from these hypotheses, includingintermodalattention and olfaction and pain, which may pose problems for Crick's original theory. This work reviews the possible role in awareness and intermodal attention and intention of the cholinergic system in the basal forebrain and the tegmentum; the reticular, the intralaminar, and the dorsomedial thalamic nuclei; the raphe and locus coeruleus; the reticular formation; the ventral striatum and extended amygdala; insula cortex, and other selected cortical areas. Both clinical and basic research data are covered. The conclusion is reached that the brain may work by largely nonlinear parallel processing and much intramodal shifts of attention may be effected by intracortical, or multiple corticothalamic mechanisms . But this is constrained by the functional anatomy of the circuits concerned and waking “awareness” is modulated by the many “nonspecific” systems . But the principal agents for intermodal attention shifts, the “searchlight,” may be two key nuclei of the cholinergic system in the mesencephalon. Clinical loss of consciousness results from damage to these nuclei but not from damage to the cholinergic nucleus basalis of the basal forebrain. (shrink)

A tacit assumption since the 19th Century has been that the neocortex serves as the "seat of consciousness." An unexpected challenge to that assumption arose in 1949 with the discovery that high-frequency EEG activation associated with an alert state requires the intactness of the brainstem reticular formation. This discovery became the impetus for nearly three decades of research on what came to be known as the reticular activating system. By the 1970s, however, methodological and philosophical controversies led to general (...) abandonment of subcortical theories of attention and consciousness, with a return to an almost exclusive focus upon the cortex. With recent advances in the neurosciences the focus is shifting once more, this time to the unique contributions of cortical, thalmic, and brainstem structures in mediating selective attention and perceptual awareness. This paper offers a nontechnical review of the history of these developments up to contemporary interest in the putative role of oscillatory EEG patterns in the integration of perceptual features of experience. It puts forward the thesis that a key to understanding attention and consciousness is an appreciation of contributions of the thalmus to these cognitive processes. (shrink)

The self/non-self distinction is essential for survival, but its neural bases are poorly understood. Studies have sought neural specificity for 'self ' in cortical regions. However, behavioural evidence showing that humans are able to single out self-relevant information in the absence of awareness suggests that the cognitive self/non-self distinction might be rooted in subcortical structures involved in automatic, unconscious functions. Here we employ subliminal presentation of self and non-self faces and repetition suppression to show neural specificity for 'self ' in (...) the brainstem reticular formation, providing the first evidence for self/non-self distinction in subcortical structures. Our finding suggests that the brainstem may act as a neural substrate for the sense of 'self '. (shrink)

The neuroanatomical substrates controlling and regulating sleeping and waking, and thus consciousness, are located in the brain stem. Most crucial for bringing the brain into a state conducive for consciousness and information processing is the mesencephalic part of the brain stem. This part controls the state of waking, which is generally associated with a high degree of consciousness. Wakefulness is accompanied by a low-amplitude, high-frequency electroencephalogram, due to the fact that thalamocortical neurons fire in a state of tonic depolarization. Information (...) can easily pass the low-level threshold of these neurons, leading to a high transfer ratio. The complexity of the electroencephalogram during conscious waking is high, as expressed in a high correlation dimension. Accordingly, the level of information processing is high. Spindles, and alpha waves in humans, mark the transition from wakefulness to sleep. These phenomena are related to drowsiness, associated with a reduction in consciousness. Drowsiness occurs when cells undergo moderate hyperpolarizations. Increased inhibitions result in a reduction of afferent information, with a lowered transfer ratio. Information processing subsides, which is also expressed in a diminished correlation dimension. Consciousness is further decreased at the onset of slow wave sleep. This sleep is controlled by the medullar reticular formation and is characterized by a high-voltage, low-frequency electroencephalogram. Slow wave sleep becomes manifest when neurons undergo a further hyperpolarization. Inhibitory activities are so strong that the transfer ratio further drops, as does the correlation dimension. Thus, sensory information is largely blocked and information processing is on a low level. Finally, rapid eye movement sleep is regulated by the pontine reticular formation and is associated with a ''wake-like'' electroencephalographic pattern. Just as during wakefulness, this is the expression of a depolarization of thalamocortical neurons. The transfer ratio of rapid eye movement sleep has not yet been determined, but seems to vary. Evidence exists that this type of sleep, associated with dreaming, with some kind of perception and consciousness, is involved in processing of ''internal'' information. In line with this, rapid eye movement sleep has higher correlation dimensions than slow-wave sleep and sometimes even higher than wakefulness. It is assumed that the ''near-the-threshold'' depolarized state of neurons in the thalamus and cerebral cortex is a necessary condition for perceptual processes and consciousness, such as occurs during waking and in an altered form during rapid eye movement sleep.

Subcortical substrates for behavioural integration include the fore/midbrain nuclei of the basal ganglia and the hindbrain medial reticular formation. The midbrain superior colliculus requires basal ganglia disinhibition in order to generate orienting movements. The colliculus should therefore be seen as one of many competitors vying for control of the body's effector systems with the basal ganglia acting as the key arbiter. (Published Online May 1 2007).

1.1 Bilateral damage to the thalamus abolishes waking consciousness. The critical site of this damage is believed to be a relatively small cluster of neurons, about the size of a pencil eraser on either side of the brain's midline, called the Intra-Laminar Nuclei (ILN) because they are located inside the white layers (laminae) that divide the two thalami into their major groupings of nuclei. The fact that bilateral damage to the ILNs abolishes consciousness is very unusual. There is no other (...) site in the brain that has this property, except the reticular formation in the brain stem. In contrast, huge chunks of cortex can be damaged without abolishing the STATE of consciousness. (Cortical damage does change the CONTENTS of consciousness, of course). (shrink)

Possible systemic effects of general anesthetic agents on neural information processing are discussed in the context of the thalamocortical suppression hypothesis presented by Drs. Alkire, Haier, and Fallon (this issue) in their PET study of the anesthetized state. Accounts of the neural requisites of consciousness fall into two broad categories. Neuronal-specificity theories postulate that activity in particular neural populations is sufficient for conscious awareness, while process-coherence theories postulate that particular organizations of neural activity are sufficient. Accounts of anesthetic narcosis, on (...) the other hand, explain losses of consciousness in terms of neural signal-suppressions, transmission blocks, and the disruptions of signal interpretation. While signal-suppression may account for the actions of some anesthetic agents, the existence of anesthetics, such as choralose, that cause both loss of consciousness and elevated discharge rates, is problematic for a general theory of narcosis that is based purely on signal suppression and transmission-block. However, anesthetic agents also alter relative firing rates and temporal discharge patterns that may disrupt the coherence of neural signals and the functioning of the neural networks that interpret them. It is difficult at present, solely on the basis of regional brain metabolic rates, to test process-coherence hypotheses regarding organizational requisites for conscious awareness. While these pioneering PET studies have great merit as panoramic windows of mind-brain correlates, wider ranges of theory and empirical evidence need to be brought into the formulation of truly comprehensive theories of consciousness and anesthesia.

Church leadership plays an important and irreplaceable role in the planting and the configuration of the missional congregation. The key to the formation of missional communities is their leadership. In that regard, this article explores Classical Ghanaian Pentecostal Churches’ leadership and leadership formation from a missiological perspective. This was done through an exposition on their leadership system. It was argued that Classical Ghanaian Pentecostal Churches’ leadership is based on the Fivefold Ministry. These leadership functions were therefore discussed in (...) the light of their missiological implication. The conclusion arrived at is that it is not enough to discover one’s spiritual gift or calling; these gifts should be developed and nurtured through mentoring and proper theological education, with the ultimate purpose being to participate in the Missio Dei.

There are two parts to this present article. First, I consider the applied problem of assessing changes in a congregation—how often to assess, why assess, what changes are looked for, what interventions are assessed, why look to the components of interventions, and how to avoid problems interpreting your data. Brief assessments are mandatory. Pastors and lay leaders can make simple but sound assessments of their spiritual formation programs using item response theory, goal attainment scales, single items, parceling single items, (...) or narrative responses as five alternatives. I describe dangers in interpreting the findings such as not knowing the base rate of change and mistaking the assessment for the mission. In the second part of the article, I briefly describe a program labeled a deep dive into humility. I summarize the assessments that were done, which gives a practical example of the technical recommendations I made earlier in the article. (shrink)

The increasing integration of artificial intelligence and virtual reality in online learning platforms has raised profound philosophical and theological questions regarding human cognition, emotional engagement, and spiritual formation. However, current virtual learning environments often overlook the significant role of emotional and affective factors in shaping user experience, particularly in the context of religious education and moral development. This study explores an emotionally designed virtual interactive learning platform, incorporating a philosophical inquiry into how technology-mediated learning affects human emotions, ethical reasoning, (...) and spiritual growth. Utilizing a MacBERT-BiSRU-AT emotion classification model, this research examines user emotional responses to virtual learning interactions, achieving an F1 score of 91.34% with efficient processing time. Findings reveal that emotionally responsive design enhances learners’ engagement, mitigates negative emotional experiences, and improves satisfaction, with over 85% of users expressing positive responses. The implications of this study extend beyond technological advancements, addressing deeper philosophical concerns about the nature of learning, digital embodiment, and the intersection of artificial intelligence with religious pedagogy. By considering users’ emotional and spiritual needs, the study suggests that emotionally intelligent design can enrich online religious education, fostering a more profound engagement with theological discourse, moral reflection, and community-based learning. Future research should further explore how AI-driven emotional design influences religious cognition, ethical development, and the metaphysical dimensions of virtual learning environments. (shrink)

Hydractinia echinata is a marine colonial hydroid, a relative of the more widely known Hydra. In contrast to Hydra, embryogenesis, metamorphosis and colony growth in Hydractinia are experimentally accessible and therefore, provide an ideal model system for investigating the biochemical basis of pattern formation. In particular, the processes involved in the transformation of the drop‐shaped freely swimming larva into a sessile tube‐shaped polyp are easily monitored, because this transfomation can be induced by application of various substances. Our results indicate (...) that the internal level of S‐adenosylmethionine (SAM), potentially the most important methyl donor in transmethylation processes, plays a key role in the onset of metamorphosis. It is also proposed that the internal level of SAM plays a pivotal role in the proportioning and spacing of polyps within the colony. (shrink)

The article examines the content and process of forming the principles of a customer-oriented approach to the management of transport enterprises in the context of sustainable development. The author's definition of the concept of “principles of a customer-oriented approach to the management of transport enterprises” is given on the basis of its understanding as strategic and tactical areas of activity aimed at maximizing the satisfaction of customers' needs and expectations through the use of digital technologies and innovative approaches. The key (...) principles of a customer-oriented approach to managing transport enterprises in the context of sustainable development are developed, among which the following are highlighted: understanding customer needs; personalization of service; interaction at all stages; digital transformation of processes; data analysis and forecasting; creation of a digital environment; training and development of personnel; culture of service and open communication; continuous analysis and improvement; focus on the sustainability of relations, etc. The author's own model of digital transformation of transport enterprises using the principles of a customer-oriented approach is proposed. A generalized characterization and impact on the processes of customer focus of individual digital technologies for managing customer relations of transport enterprises is presented. (shrink)

Contemporary educational theorists focus on the significance of Dewey’s conception of experience, learning-by-doing and collateral learning. In this essay, I reexamine the chapters of Dewey’s Democracy and Education, that pertain to thinking and highlight their relationship to Dewey’s How We Think: A Restatement of the Relation of Reflective Thinking in the Educative Process—another book written explicitly for teachers. In How We Think Dewey explains that nothing is more important in education than the formation of concepts. Concepts introduce permanency into (...) an otherwise impermanent world. He defines concepts as established meanings, or intellectual deposits used to found a better understanding of new experiences; they are what makes any experience educationally worthwhile. Dewey accuses traditional and progressive education of failing to appropriately form concepts in students. His position is that concepts are formed and transformed by experience, reflection and activity. He argues that the individual makes a personalized use of concepts for which he or she requires: continuity of experience, exposure to new or surprising possibilities, and sustained communication with others—all of which are discussed at length in Democracy & Education. I conclude with the practical recommendation that K-12 schools introduce philosophy into the curriculum. Philosophy not only invites students to engage their concepts in a reflective manner, but it also provides a valuable resource for that engagement. Most if not all of philosophy’s canonical texts are dedicated to analyzing such concepts as beauty, friendship, love and justice. The introduction of philosophy in K-12 education would, I suggest, offer a correction to both traditional and progressive education. (shrink)

Concept formation in science is a reasoned process, commensurate with ordinary problem-solving processes. An account of how analogical reasoning and reasoning from imagistic representations generate new scientific concepts is presented. The account derives from case studies of concept formation in science and from computational theories of analogical problem solving in cognitive science. Concept formation by analogy is seen to be a process of increasing abstraction from existing conceptual structures.

One of the important determinants of development during the transition to adulthood is the undertaking of social roles characteristic of adults, also in the area of finishing formal education, which usually coincides with beginning fulltime employment. In the study discussed in this paper, it has been hypothesized that continuing full-time education above the age of 26, a phenomenon rarely observed in Poland, can be considered as an unpunctual event that may be connected with difficulties in the process of identity (...) class='Hi'>formation. Relationships between identity dimensions and identity statuses, and age and educational context were analyzed. 693 individuals aged 19-35 took part in the study. The participants attended three types of educational institutions: full-time university studies, part-time university studies, and full-time post-secondary school. Among the students of full-time university studies predictable dependencies, also in respect of highlevels of indicators of identity crisis and a high frequency of diffused identity occurrence, were observed. Such dependencies were not found in the group of full-time post-secondary school students. (shrink)

When outer objects are seen, it is through mediation by the epistemologically more immediate items, ‘the visual given’ and ‘the visual mediators’. There is reason for thinking that seeing is the result of a two‐stage causal transaction, the first is the psycho‐physical causation of a sensuous array in body‐relative physical space, the second the psycho‐psycho causing by the latter of a mental process that subjects that array to organizing/interpreting in the forming of the visual experience. ‘The given’ names the psychological (...) product of the first transaction: it is the hypothesized middle term in a hypothesized causal triple. Then since the order/meaning in the content of visual experience is wholly determined by the susceptibility of the perceiving mind, ‘The given’ must single out the sensuous array under its minimum description. Meanwhile ‘the visual mediators’ names a set of perceptual go‐betweens, which are proxy for the object, such as light/surface/colour. Their perception is at once that through which object‐perception occurs, and the form taken by it. Finally, it is proposed that the formation of the internal object of the visual experience takes the following form: the mind constitutes out of the ‘given’ a two‐dimensionally ordered internal object, which in turn explanatorily precedes and causes the acquisition of the more ambitious internal visual objects.

In this paper, I provide an explication and defense of Merleau-Ponty’s theory of concept formation. I argue that at the core of this theory is a distinction between concepts proper and the kinds of generalities characteristic of perceptual experience, which I call “pre-conceptual generalities.” According to Merleau-Ponty, concepts are developed through a two-stage process: first, the establishment of such pre-conceptual generalities, and second, the clarification of these generalities into concepts. I provide phenomenological evidence for the existence of pre-conceptual generalities (...) and explain how they can serve to ground concept formation. To motivate Merleau-Ponty’s account, I consider objections raised by Husserl, Cassirer, and Sellars to the classical philosophical account of empirical concept formation, abstraction. I show that Merleau-Ponty’s distinction between concepts and pre-conceptual generalities provides a philosophically viable account of the formation of empirical concepts while avoiding the problems faced by accounts that rely on abstraction.

This article is a review of Tom Tyler’s CIFERAE: A Bestiary in Five Fingers, a timely and crucial contribution to critical animal studies scholarship. CIFERAE is a remarkable and careful analysis of epistemological anthropocentrism – in particular, what Tyler calls a “first-and-foremost anthropocentrism” - and the ways in which animals ‘figure’ in the history of Western thought. Moreover, the text prompts a critique of ‘the human’ and the formation of the ‘we.’ As such, Tyler’s philosophical investigation or bestiary pertains (...) not only to theories of knowledge, but holds significant ethical and political implications.

This paper explores a dynamic model of sequential club formation in which identical individuals join or leave clubs over time and their preferences depend solely on the number of members in the club. There exists a unique optimal-sized club which maximises per-period payoff of each individual. To study the implications of the dynamic setting, we use a benchmark game of a finite number of periods which mimics the static framework. Implied by the dynamic nature of the problem, we find (...) a new source of inefficiency that is caused by so called fear of exclusion phenomenon where individuals fear being excluded from a relatively superior sustainable club, which is not necessarily optimal. An unusual behaviour may be observed in which individuals strictly prefer to form sub-optimal sized clubs. A specific class of equilibria is analysed to examine such behaviour. (shrink)

This book investigates the ubuntu theory-based conception of virtue and moral character formation in the northern, western, and eastern regions of Africa, suggesting a critical reconstruction of ubuntu by conceptualising the four different forms of practices in moral character formation. Arguing for the critical reconstruction of ubuntu virtue theory as more nuanced than simply the standard ubuntu normative virtue theories (which give priority to the community as the sole locus for understanding virtues and character formation in Africa), (...) the book builds a comprehensive model of virtue and moral character formation that draws insights from the reconstructed notion of ubuntu and other theories within and beyond the African thought. Chapters feature experience from across Africa including Malawi, Zambia, Zimbabwe, Uganda, Kenya, and South Africa, and centre on topics such as traditional cultural views and practices, political systems in various nations, neoliberalist thought, and primary, secondary and tertiary education systems in Africa and further afield. This is a valuable resource for scholars, academics, and postgraduate students, working in the fields of moral and values education, philosophy of education, and the theory of education more broadly. Those also interested in educational psychology may also find the volume of interest. (shrink)

Modern Christians often polarize the otherwise inseparable realities of academic reading and personal reading of Scripture. While generally not declared outright, many Christians consider the two methods discontinuous. This article deems this bifurcation unnecessary and dangerous to the spiritual formation of individuals and the spiritual health of the church.

The article shall argue that Bonaventure's quadrigal method ought to be (...) retrieved today for the spiritual health of scholarship and the church. This thesis will be attained organically. It will first survey his proposed method of interpretation in his Breviloquium and Commentary on the Gospel of Luke; then, it will appeal to scriptural and pastoral support to show that his method is a helpful route for retrieval.

The third Christian millennium has dawned and global Christianity has been making a drastic shift from the north to the south. This also coincides with the beginning of the post-Christendom era. How these two mega shifts would impact theological education and missional formation is an active discussion today. The study, intended to be a preliminary conversation starter, is a reflection of a southern Christian. It identifies three major components that have been developed, altered, or even dropped in the Christendom (...) process, and how the new era affords world Christianity with a rare opportunity to evaluate, revision, and restore the vision of theologising and theological formation. A fourth component is added to counter-balance the de-Christendom attempts that took place in the twentieth century, which also illustrates the complexity of, and the limitation to, the argument that is presented here.

This paper addresses the question of how Robertson's History of America depicts the transition of world history from pre-modern disorder to a recognisably modern commercial order. It argues that in his narrative of action he moves beyond the limitations imposed by stadial forms of history, with which America is usually associated, and displays the importance of disordered forms of activity as a creative force in shaping the modern world. It concludes by suggesting that a close reading of his history does (...) not support Robertson's assumptions concerning the formation of a stable, ordered and industrious ‘commercial character’ out of this process, but rather establishes a more complex and less teleological path to modernity. ☆ This paper was presented in abbreviated form at the conference on ‘Political Economy and 18th Century Scottish Culture’ at George Mason University, June 2001.

The notion of exploratory modeling constitutes a powerful heuristic tool for historical-epistemological analysis and especially for studying concept formation. I will show this by means of a case study from the history of particle physics: the formation of the concept of “strangeness” in the early 1950s at the interface of theory and experiment. Strangeness emerged from a broad space of possibilities opened up by exploratory modeling by authors working in communication and competition, and constructing both new questions and (...) new answers. A systematic focus on exploratory modeling also helps compensate a bias towards the “right” developments still often present in historical investigations of theoretical work. (shrink)

If we inspect closely the works that ascend to world literature from the peripheral, David Damrosch’s well-recognized argument that “world literature is writing that gains in translation” may need some revision, because apparently translation is not the sole factor that decides the formation of world literature. Translated works do not necessarily represent the best part in one national literature. Damrosch’s overemphasis on translation differences and untranslatability in world literature tends to overlook the syncretism of heterogeneous literatures: The influence of (...) Roman Empire on Indian Buddhism, the influx of elements from Indian, Arabic, and Persian stories into European writers’ creation, the genres of China’s ancient literature influenced by Buddhism, etc. Furthermore, a great deal of Chinese idioms and allusions appearing in Japanese, Korean and Vietnamese literatures provide us a general view of how world literature forms through exchange and syncretism. On this account, Damrosh’s argument may be reformulated as “world literature is writing that gains in variation.” Variation reflects the ability to absorb otherness and then to create something new. Meanwhile, the perspective of literary syncretism will help us reasonably distinguish world literature and national canons. (shrink)
