This paper describes how Tononi’s information integration theory of consciousness was used to make detailed predictions about the distribution of phenomenal states in a spiking neural network. This network had approximately 18,000 neurons and 700,000 connections and it used models of emotion and imagination to control the eye movements of a virtual robot and avoid ‘negative’ stimuli. The first stage in the analysis was the development of a formal definition of Tononi’s theory of consciousness. The network was then (...) analysed for information integration and detailed predictions were made about the distribution of consciousness for each time step of recorded activity. This work demonstrates how an artificial system can be analysed for consciousness using a particular theory and in the future this approach could be used to make predictions about the phenomenal states associated with biological systems.

Some patients awaken from their coma but only show reflex motor activity. This condition of wakeful (eyes open) unawareness is called the vegetative state. In 2002, a new clinical entity coined ‘‘minimally conscious state’’ defined patients who show more than reflex responsiveness but remain unable to communicate their thoughts and feelings. Emergence from the minimally conscious state is defined by functional recovery of verbal or nonverbal communication.1 Our empirical medical definitions aim to propose clearcut borders separating disorders of consciousness (...) such as coma, vegetative state and minimally conscious state but clinical reality shows that these boundaries can often be fuzzy (fig 1). Recent clinical, electrophysiological and neuroimaging studies are shedding light on these challenging limits of consciousness encountered following severe acute brain damage. At the patient’s bedside, it is very challenging to differentiate reflex or automatic motor behaviour from movements indicating signs of consciousness, and hence some minimally conscious patients might be misdiagnosed as being vegetative. For some motor responses (eg, blinking to visual threat, brief fixation, normal flexion response to pain, etc) it remains unclear whether they truly are voluntary or willed because we lack convincing scientific evidence. We also lack consensus on how to practically assess some of these behavioural responses. For example, there is no agreement on what stimulus to employ in the assessment of visual pursuit movements— often one of the first clinical signs heralding the transition from the vegetative to the minimally conscious state. Vanhaudenhuyse and colleagues2 recently studied visual pursuit in 51 post-comatose patients comparing eye tracking of a moving object, person or mirror. It was shown that more.. (shrink)

Consciousness and its relation to the unconscious mind have long been debated in philosophy. I develop the thesis that consciousness and its contents reflect the highest elaboration of a set of abilities to respond to the environment realized in more primitive organisms and brain circuits. The contents of the states lesser than consciousness are, however, intrinsically dubious and indeterminate as it is the role of the discursive skills we use to construct conscious contents that lends articulation and (...) clarity to the mental acts which cumulatively make up our mental lives. I lay out a tripartite structure for the formation of mind in which the ongoing interaction between brain and world, the formative effect of socio-cultural context and the self production of a relatively coherent narrative all play an important part in making a mind. The latter two influences clearly transcend biological science and suggest that human minds have features which broadly align with certain Freudian insights but do not support the reification of the causally structured unconscious that Freud envisaged.

When observers view a rapidly moving stimulus they may see only a static streak. We report that there can be a transient percept of motion if such a moving stimulus is preceded or followed by a stationary image of that stimulus. A ring of dots was rotated so rapidly observers only saw a continuous outline circle and could not report its rotation direction. When an objectively stationary ring of dots preceded or followed this rotating ring, the stationary ring appeared to (...) visibly launch into motion from a standstill or visibly rotate to a halt, principally in the same direction as the actual rapid rotation. Thus, motions too rapid to be consciously perceived as motion can nonetheless be processed by the visual system, and generate neural transition states that are consciously experienced as motion percepts. We suggest such transition states might serve a unifying function by bridging discontinuous motion states. (shrink)

How are the states of consciousness intrinsically so that they all qualify as ?feelings? in William James?s generic sense? Only a small, propaedeutic part of what is required to address the intrinsic nature of such states can be accomplished here. I restrict my topic mainly to a certain characteristic that belongs to each of those pulses of mentality that successively make up James?s stream of consciousness. Certain statements of James?s are intended to pick out the variable ?width? belonging (...) to a stream of consciousness as it flows. Attention to this proposed property brings me to a discussion of (a) the unitary character of each of the states of consciousness however complex they may frequently be and (b) how to conceive of their complexity without recourse to a misleading spatial metaphor.

A biophysical and biochemical perspective of Brahmajnaana will be advanced by viewing Upanishads and related books as “Texts of Science on human mind”. A biological and cognitive science insight of Atman and Maya, the results of breathing process; constituting and responsible for human consciousness and mental functions will be developed. The Advaita and Dvaita phases of human mind, its cognitive and functional states will be discussed. These mental activities will be modeled as brain-wave modulation and demodulation processes. The energy-forms (...) and their transformations as ideas/moods/experiences/thoughts/feelings/utterances/knowing/perception/experience/mood; and a theory of human cognition and communication will be advanced. The sameness of these and processes taking place and steps involved in human language acquisition and communication processes will be highlighted taking ideas from Sabdabrahma Siddhanta and Sphota Vaada, for which the basis is Brahmajnaana only. In fine, a physiological psychological and neurological model of human consciousness and function of mind based on Indian spiritual thought will be derived and discussed using concepts from modern science and technology. The application of these derivations in the fields of physiological psychology, mind-machine modeling, natural language comprehension branch of artificial intelligence and neurology to model and imitate human mental functions will be hinted. -/- .

This dissertation presents evidence that a number of the great traditional Western metaphysicians based their metaphysical systems upon their experiences of altered states of consciousness . It poses the question: what state of consciousness would be necessary for the metaphysician to actually experience "reality" in the way that he describes it? It specifically discusses evidence in the philosophical writings of Plato, Berkeley, Schopenhauer and Hegel which strongly suggests that they experienced various non-ordinary planes of "reality" during certain ASCs. (...) ;Four different metaphysical planes or levels of "reality" are presented: the everyday material world , the eternal soul , the archetypal Platonic Ideas or essences and the Divine Mind of God , which is identified with the mystical godhead. ;It is argued that Plato directly experienced the non-ordinary realm of the eternal Ideas . Berkeley's metaphysical claims about the unreality of matter and the dependence of the entities in the everyday world upon the mind or soul for their existence are grounded in his direct experience of the soul during a worldless ASC. Schopenhauer's description of the aesthetic experience of the Platonic Ideas is discussed as a perceptual form of concentrative meditation. Hegel's fundamental metaphysical concept of the Universal Mind of God or Absolute Spirit is rooted in his mystical experiences of Level Four. His non-Aristotelian form of logic is described as a "state-specific logic," i.e., a form of logic which is rooted in the experience of a specific ASC. ;It is argued that "analytic" philosophers have misunderstood the experiential nature of traditional metaphysical language. Some of the implications of this experiential approach to philosophy are explored in terms of the notion of "state-specific metaphysical systems.". (shrink)

If one were to write a book titled TheVarieties of Self-Consciousness, one would start off with some distinctions. It will help to locate my topic in relation to those distinctions.The first distinction concerns that kind of self-consciousness which involves only the minimal ability on the part of a subject to self-represent, to be in mental states with first person content, be it conceptual or nonconceptual. This minimal ability involves very little as compared with the more sophisticated states of (...) which humans are capable. First person content can be present in the perceptual states of a creature capable of representing only some of its physical states and its relations to the physical environment, and not capable of representing anything beyond that. So the first distinction is between this minimal case, and richer varieties of self-consciousness. Some writers use ‘self-conscious’ to apply to a subject who is in any mental state involving first person content, and so they would appl. (shrink)

In The Varieties of Religious Experience, James explores in some depth, among much else, a kind of dividedness that can exist within the stream of consciousness — “the divided self.” This condition of the stream consists in crucial part of a phenomenological heterogeneity, inconsistency, discordance, or division of which disapproving notice is taken subjectively. The pertinent discordance exists among states of consciousness that comprise the same stream, is evident directly to inner awareness, and is not necessarily a matter (...) of positing or inferring the existence of a second stream of consciousness or an unconscious mental life. Typically, intrinsic theorists of inner awareness — or the immediate awareness we all have of at least some of our own mental-occurrence instances — disagree with appendage theorists concerning, inter alia, what the firsthand evidence reveals about inner awareness. I proffer in the present article an hypothesis that should help to explain why the first-person reports of appendage theorists contradict intrinsic theory with regard to inner awareness. My hypothesis derives from James’s discussion in Varieties of the not uncommon divided-self phenomenon. (shrink)

Explanation does not exist in a metaphysical vacuum. Conceptions of the structure of a phenomenon play an important role in guiding attempts to explain it, and erroneous conceptions of a phenomenon may direct investigation in misleading directions. I believe that there is a case to be made for thinking that much work on the neural underpinnings of consciousness—what is often called the neural correlates of consciousness—is driven by an erroneous conception of the structure of consciousness. The aim (...) of this paper is lay bare some connections between the explanation of consciousness and the structure of consciousness, and to argue for a conception of the structure of consciousness that is more adequate than that which currently drives much research into the neural correlates of consciousness.

The concept of futility is sometimes regarded as a cloak for medical paternalism in that it rolls together medical and value judgments. Often, despite attempts to disambiguate the concept, that is true and it can be applied in such a way as to marginalize the real interests of a patient. I suggest we replace it with a conceptual toolkit that includes physiological futility, substantial benefit (SB), and the risk of unacceptable badness (RUB) in that these concepts allow us to articulate (...) what is at stake in ethical judgments where outcomes are crucial in determining what should be done.

The law of coherence helps us understand the physical force behind the increasing complexity of the evolutionary process, from quanta, to cells, to self-awareness and collective consciousness. The coherent electromagnetic field is the inner glue of every system, the "intelligent" energy-information communication that assures a cooperative and synergic behavior to all the components of the system, as a whole, allowing harmonious evolution and unity of consciousness. Neuropsychological experiments show that the different brain areas communicate with more or less (...) coherence according to different states of consciousness: high values are correlated with states of psychophysical integrity and well-being, whereas low values with states of conflict and depression. If we expand isomorphically these brain discoveries, we will have four main general states of coherence: from disgregation to unity, which represents an important element, in the General System Theory, to differentiate between inanimate and animate system, and to understand how billions cells become a single living organism, and then how billions of human beings could eventually generate planetary consciousness. In this light the resolution of the global ecosystem crisis implicates human transformation from a low to a highly coherent state of consciousness. The key to the entire process seems to be the coherent nature of consciousness. (shrink)

To further illuminate the nature of conscious states, it may be progressive to integrate Merker's important contribution with what is known regarding (a) the temporal relation between conscious states and activation of the mesodiencephalic system; (b) the nature of the information (e.g., perceptual vs. premotor) involved in conscious integration; and (c) the neural correlates of olfactory consciousness.

The field of affective neuroscience has emerged from the efforts of Jaak Panksepp in the 1990s and reinforced by the work of, among others, Joseph LeDoux in the 2000s. It is based on the ideas that affective processes are supported by brain structures that appeared earlier in the phylogenetic scale (as the periaqueductal gray area), they run in parallel with cognitive processes, and can influence behaviour independently of cognitive judgements. This kind of approach contrasts with the hegemonic concept of conscious (...) processing in cognitive neurosciences, which is based on the identification of brain circuits responsible for the processing of (cognitive) representations. Within cognitive neurosciences, the frontal lobes are assigned the role of coordinators in maintaining affective states and their emotional expressions under cognitive control. An intermediary view is the Damasio-Bechara Somatic Marker model, which puts cognition under partial somatic-affective control. We present here our efforts to make a synthesis of these views, by proposing the existence of two interacting brain circuits; the first one in charge of cognitive processes and the second mediating feelings about cognitive contents. The coupling of the two circuits promotes an endogenous feedback that supports conscious processes. Within this framework, we present the defence that detailed study of both affective and cognitive processes, their interactions, as well of their respective brain networks, is necessary for a science of consciousness.

For the past two decades, my research has primarily focused on two interrelated questions: 1)What do the data from mysticism and non-ordinary states of consciousness imply about the nature of consciousness understood broadly? 2) In what ways does a careful examination of the nature of consciousness illuminate the processes that undergird mysticism and non-ordinary states of consciousness? In my attempts to offer coherent, cogent, and compelling answers to these questions, I have been helped, immeasurably, by the (...) work of William James and Henri Bergson. I have already written a book on each figure,1 so I am keenly aware that this essay will be unable to encapsulate, even partially, the richness and depth of their respective perspectives on this provocative subject matter. Nonetheless, I am delighted to have been given the opportunity to underscore some of the insights offered by James and Bergson that over the years have continued to inspire me. (shrink)

Higher states of consciousness in which the human mind can transcend the boundaries of logic and reason are envisioned as natural to the experience and potential growth of every human being. So far they have been mostly monitored by electrophysiological methods. In this study we were particularly interested in discovering the molecular transcriptional basis of higher states of consciousness. In addition to phenomenological reports of meditators who participated in this study the generated higher states of consciousness were (...) also EEG recorded. We assessed the whole genome gene expression analysis of long-term meditators in four separate trials and detected significant differential gene expression in association with higher states of consciousness. The number of differently expressed genes as well as high proportion of genes themselves differed between meditators. Despite this, gene ontology enrichment analysis found significant biological and molecular processes shared among meditators’ higher state of consciousness. (shrink)

This book draws on transpersonal anthropology and psychology in order to explore mild altered states of consciousness (ASCs) experienced in everyday life. While research into consciousness and particularly ASCs is growing, this book focuses on a neglected area: ‘everyday’ experiences of ASCs. Opening with an up-to-date overview of the development of the study of ASCs, the author presents an in-depth empirical exploration and mapping of mild ASCs. Dr Sheppard examines original research conducted in a range of religious and (...) secular contexts with participants who were engaged in activities including prayer, sport, nature conservation, music and musical instrument making, and TV viewing. The author takes a novel phenomenological approach to the analysis of ASCs, emphasising the subjective experience. The book explores the healing potential of such mild ASCs; the everyday fantasy reality of the interior landscape; and discusses the problem of validity, and belief in the study of ASCs. It will appeal to students and scholars of transpersonal psychology, consciousness studies, social anthropology, and the philosophy of mind. (shrink)

Pseudoscience is not an appropriate label for parapsychology. Although the noise reduction model of extrasensory perception (ESP) is explanatory only in a limited sense, research does exist addressing the correlation between ESP and altered states of consciousness (ASCs). The term anomaly is not appropriately applied to experiences such as out of body experiences (OBEs) per se, but only to the question of their source. Research on both topics should be encouraged.

One of the final obstacles to understanding consciousness in physical terms concerns the question of whether conscious states can exist in posterior regions of the brain without active connections to the brain's prefrontal lobes. If they can, difficult issues concerning our knowledge of our conscious states can be resolved. This paper contains a list of types of conscious states that may meet this criterion, including states of coma, states in which subjects are absorbed in a perceptual task, states in (...) brains with damaged prefrontal lobes, states of meditation and conscious states of some infants and animals. Recent evidence also suggests that conscious states of some people with autism may meet this criterion. (shrink)

Anthropologists working on altered states of consciousness (ASC) have suggested that we should do away with psychologizing concepts and use people's own terms for these experiences. With material drawn from the Orang Sakai of Sumatra this paper shows that practitioners who utilize ASC do recognize the alteration of states of awareness as preconditions for numinous interactions. Also critically discussed is the term ASC.

In the spirit of William James, we present a process view of human consciousness. Our approach, however, follows upon Charles Tart’s original systems theory analysis of states of consciousness, although it differs in its reliance on the modern sciences of complexity, especially dynamical systems theory and its emphasis on process and evolution. We argue that consciousness experience is constructive in the sense that it is the result of ongoing self-organizing and self-creating processes in the mind and body. (...) These processes follow a broad developmental agenda already described by psychologists such as Jean Piaget. Similar constructive transformations of consciousness appear to have occurred across the course of human history. In this sense, phylogeny indeed recapitulates ontogeny. Finally, modern developmental research suggests that the most advanced levels of human growth transform consciousness in the direction of increasing selflessness and spirituality, rather than simply toward greater intelligence.

It is suggested that the anatomical structures whichmediate consciousness evolved as decisiveembellishments to a (non-conscious) design strategypresent even in the simplest monocellular organisms.Consciousness is thus not the pinnacle of ahierarchy whose base is the primitive reflex, becausereflexes require a nervous system, which the monocelldoes not possess. By postulating that consciousness isintimately connected to self-paced probing of theenvironment, also prominent in prokaryotic behavior,one can make mammalian neuroanatomy amenable todramatically simple rationalization.

This is an interview with author Ken Wilber, whose work on consciousness over the last twenty‐five years has been tremendously influential. His work blends "Eastern" and "Western" approaches and has influenced scholars in psychology, philosophy, and religion, as well as in anthropology. His work on transpersonal psychology is especially well‐known, and his first book, The Spectrum of Consciousness, arguably marks the beginning of transpersonal studies. Frances Vaughan has referred to Wilber's work as the "work of genius." Daniel Goleman (...) once listed Wilber among the "ranks of the grand theorists of human consciousness" including "Ernst Cassirer, Mircea Eliade, and Gregory Bateson." Wilber discusses the scope of the consciousness problem as well as contributions to the field that anthropologists might be well suited to make. (shrink)

I draw attention to an ambiguity of the expression ‘phenomenal consciousness’ that is an avoidable yet persistent source of conceptual confusion among consciousness scientists. The ambiguity is between what I call phenomenality and what I call conscious states, where the former denotes an abstract property and the latter denotes a phenomenon or class of its instances. Since sentences featuring these two terms have different semantic properties, it is possible to equivocate over the term ‘consciousness’. It is also (...) possible to fail to distinguish between statements that are true about conscious states in virtue of their phenomenality, and statements that are true in virtue of other properties of conscious states. I review empirically informed arguments by scientists Bernard Balleine and Anthony Dickinson, Stevan Harnad, and Jeffrey Alan Gray, arguing that each of them makes errors based on the ambiguity. I conclude with some tentative suggestions for avoiding further confusion about the ambiguity. (shrink)

An example is presented of a model of consciousness based on a description of the world which integrates the material and psychological aspects from the start. An indication is given of work under way to test the model.

I argue that a dual-aspect theory of consciousness, associated with a particular class of quantum states, can provide a consistent account of consciousness. I illustrate this with the use of coherent states as this class. The proposal meets Chalmers 'requirements of allowing a structural correspondence between consciousness and its physical correlate. It provides a means for consciousness to have an effect on the world in a way that supplements and completes conventional physics, rather than interfering with (...) it. I draw on the work of Hameroff and Penrose to explain the consistency of this proposal with decoherence, while adding details to this work. The proposal is open to extensive further research at both theoretical and experimental levels. (shrink)

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between (...) the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep. (shrink)
