Psychology is dead. The self is a fiction invented by the brain. Brain plasticity isn?t all it?s cracked up to be. Our conscious learning is an observation post factum, a recollection of something already accomplished by the brain. We don?t learn to speak; speech is generated when the brain is ready to say something. False memories are more prevalent than one might think, and they aren?t all that bad. We think we?re in charge of our lives, but actually we are (...) not. On top of all this, the common belief that reading to a young child will make her brain more attuned to reading is simply untrue.

After the first callosotomy surgeries were performed, the general consensus among the medical community was that severing the corpus callosum had relatively little, if any, effect on an individual's behavior. Nearly twenty years later, researchers discovered that, under experimental conditions, the two hemispheres could simultaneously maintain very different interpretations of the same stimulus. These findings immediately called into question the unity of subjective experience, a fundamental characteristic of human consciousness. How could the split‐brain patient not experience any disruption in his (...) experience as a unified self when the two hemispheres are physically and functionally disconnected? In this chapter, we review the research that has led to a conceptualization of the split brain as two minds within one body and the implications of this research for the scientific study of consciousness. We argue that consciousness is a neural function that emerges from the integration of information across available functional modules. (shrink)

Michael S. Gazzaniga, a pioneer and world leader in cognitive neuroscience, has made an initial attempt to develop neuroethics into a brain-based philosophy of life that he hopes will replace the irrational religious and political belief-systems that still partly govern modern societies. This article critically examines Gazzaniga’s proposal and shows that his actual moral arguments have little to do with neuroscience. Instead, they are based on unexamined political, cultural and moral conceptions, narratives and values. A more promising way (...) of interpreting the belief-forming system of the brain is to say that we cannot avoid thinking in terms of wider frameworks and narratives that are socially embedded and historically developed; consequently, any moral discussion has to be in terms of these frameworks and narratives.

Michael S. Gazzaniga is a renowned cognitive neuroscientist. He was Editor-in-Chief of the 1447 page book The Cognitive Neurosciences, which, for the past decade, has been the fattest book in my library, apart from the ‘unabridged’. His recent book The Ethical Brain has a Part III entitled “Free Will, Personal Responsibility, and the Law”. This Part addresses, from the perspective of cognitive neuroscience, some of the moral issues that have been dealt with in the present book. The aim of (...) this Part III is to reconcile the materialist idea that brain activity is determined with the notion of moral responsibility, which normally depends upon the idea that we human agents possess free will.

: Michael Gazzaniga, a prominent cognitive neuroscientist, has argued against reductionist accounts of cognition. Instead, Gazzaniga defends a form of non-reductive physicalism: epistemological neuro-cognitive non-reductionism and ontological monist physicalism. His position is motivated by the theses that: cognitive phenomena can be realized by multiple neural systems; many outcomes of these systems are unpredictable; and multi-level explanations are required. Epistemological neuro-cognitive non-reductionism is presented as the most appropriate stance to account for the way in which phenomena should be explained (...) in cognitive neuroscience. In this paper, I argue, however, that a recent form of neuro-cognitive reductionism, namely neo-mechanistic reductionism accounts for the arguments presented by Gazzaniga. Thus, the theory offers a more consistent and well-articulated view of the relationship between cognitive and neural phenomena that is specifically compatible with the explanatory strategies and aims of contemporary cognitive neuroscience. Keywords: Neo-mechanistic Philosophy; Michael Gazzaniga; Non-reductionism; Reductionism; Philosophy of Cognitive Neuroscience L’antiriduzionismo neurocognitivo di Michael Gazzaniga e la sfida della riduzione neomeccanicista Riassunto: Uno dei più importanti neuroscienziati dei nostri tempi, Michael Gazzaniga, si è schierato contro una concezione riduzionista della cognizione. Al contrario Gazzaniga difende una forma di fisicalismo non-riduzionistico che risulta dalla combinazione, sul piano epistemologico, di un anti-riduzionismo cognitivo e, sul piano ontologico, di un monismo fisicalista. La sua posizione è motivata dalla tesi per cui i fenomeni cognitivi possono essere realizzati da molteplici sistemi neurali; molti esiti di tali sistemi non si possono prevedere; e sono pertanto necessarie spiegazioni a livelli plurimi. La concezione presentata come più adeguata per dare conto sul piano epistemologico di come i fenomeni dovrebbero essere spiegati all’interno delle neuroscienze cognitive è una forma di anti-riduzionismo neuro-cognitivo. In questo articolo si sostiene tuttavia che una recente forma di riduzionismo neuro-cognitivo può dare conto degli argomenti presentati da Gazzaniga. Si tratta di una teoria che offre una interpretazione maggiormente coerente ed articolata della relazione fra fenomeni cognitivi e neurali e che offre un modello di spiegazione compatibile con gli scopi esplicativi delle neuroscienze cognitive contemporanee. Parole chiave: Filosofia neomeccanicista; Michael Gazzaniga; Nonriduzionismo; Riduzionismo; Filosofia della neuroscienza cognitiva. (shrink)

A review, with reflections, of Michael S. Gazzaniga's (2011) book, Who's in Charge? Free Will and the Science of the Brain. Gazzaniga, a distinguished neuroscientist, wishes to connect contemporary understandings of the functioning of the human brain to the proper functioning of the American courtroom. What effect, if any, should these current understandings (and current technologies) have on legal conceptions of personal responsibility, guilt, and punishment? If, as many neuroscientists hold, the functioning of the brain wholly determines the (...) functioning of the mind, can people rightly be held responsible for their actions? Gazzaniga argues that they can. (shrink)

This essay selectively reviews, from an historical and philosophical perspective, the dopamine (DA) hypothesis of schizophrenia (DHS; Table 1 lists the abbreviations used in this essay). Our goal is not to adjudicate the validity of the theory—although we arrive at a generally skeptical conclusion—but to focus on the process whereby the DHS has evolved over time and been evaluated. Since its inception, the DHS has been the most prominent etiologic theory in psychiatry and is still referred to widely in current (...) textbooks (e.g., Buchanan and Carpenter, Jr. 2005, 1336; Cohen 2003, 225; Gazzaniga 2004, 1257;Kandel et al. 2000, 1200). Understanding its origins and evolution should help to clarify the nature of modern .. (shrink)

Z propozycją rekalibracji etyki i zastąpienia jej neuroetyką wystąpiła Patricia S. Churchland. Churchland twierdzi, że im bardziej rozumiemy szczegóły funkcjonowania naszego systemu nerwowego, tym bardziej jesteśmy przekonani co do tego, że przyjmowane przez nas standardy moralnego działania są uwarunkowane neurobiologicznie. Od roku 2002 termin „neuroetyka” funkcjonuje jako nazwa nowej subdyscypliny etyki. Wymienia się w niej dwa zasadnicze działy: etykę neuronauki i neuronaukę etyki. Pierwszy dotyczy zasadniczo moralnych problemów związanych z zastosowaniem osiągnięć neuronauk, przedmiotem drugiego: neuronauki etyki, jest wpływ, jaki wiedza (...) z zakresu neuronauk ma na nasze rozumienie etyki. Artykuł jest krytyczną prezentacją nowej subdyscypliny etycznej i próbą pokazania, że jakkolwiek neurobiologiczne procesy mają wpływ na nasze działanie, to nie decydują o jego moralnym wymiarze.

Theories of discursive integration form a group of theories that see the principles responsible for the integration of experience data (apperception) in the practices and schemes of discourse. These theories indicate that the use of language unites and organizes experience data. Their main assumption can be expressed as follows: this integration does not inhere in objects and cannot be derived from them; hence this integration cannot be secondarily expressed in language, but results exclusively from the use of language (or discourse). (...) In this article, Witold Marzęda gives an overview of narrativist theories, script theories, Gazzaniga and Dennett’s models, which refer to evolutionary psychology, and the theories of Lakoff and Johnson – all these being theories of discursive integration. Marzęda’s main objective is to formulate a paradox, which consists in a trap of self-referentiality into which these theories fall: they postulate some general properties of discourse, which, firstly, do not have to become at once the properties of individual models and which, secondly, do not admit of falsification.

This paper explores a remarkable convergence of ideas and evidence, previously presented in separate places by its authors. That convergence has now become so persuasive that we believe we are working within substantially the same broad framework. Taylor's mathematical papers on neuronal systems involved in consciousness dovetail well with work by Newman and Baars on the thalamocortical system, suggesting a brain mechanism much like the global workspace architecture developed by Baars (see references below). This architecture is relational, in the sense (...) that it continuously mediates the interaction of input with memory. While our approaches overlap in a number of ways, each of us tends to focus on different areas of detail. What is most striking, and we believe significant, is the extent of consensus, which we believe to be consistent with other contemporary approaches by Weiskrantz, Gray, Crick and Koch, Edelman, Gazzaniga, Newell and colleagues, Posner, Baddeley, and a number of others. We suggest that cognitive neuroscience is moving toward a shared understanding of consciousness in the brain. (shrink)
