This book brings together an international group of neuroscientists and philosophers who are investigating how the content of subjective experience is correlated with events in the brain. The fundamental methodological problem in consciousness research is the subjectivity of the target phenomenon -- the fact that conscious experience, under standard conditions, is always tied to an individual, first-person perspective. The core empirical question is whether and how physical states of the human nervous system can be mapped onto the content of conscious experience. The search for the neural correlates of consciousness (NCC) has become a highly active field of investigation in recent years. Methods such as single-cell recording in monkeys and brain imaging and electrophysiology in humans, applied to such phenomena as blindsight, implicit/explicit cognition, and binocular rivalry, have generated a wealth of data. The same period has seen the development of a number of theories about NCC location. This volume brings together the leading experimentalists and theoreticians in the field. Topics include foundational and evolutionary issues, global integration, vision, consciousness and the NMDA receptor complex, neuroimaging, implicit processes, intentionality and phenomenal volition, schizophrenia, social cognition, and the phenomenal self.

Page 103 - ... of our ancestors (embodied in our genes), and to make this interpretation directly available, for a sufficient time, to the parts of the brain that contemplate and plan voluntary motor output, of one sort or another, including speech.
Page 42 - ... constituents of the same kind as A, B, and C in relations of the same kind as R have certain characteristic properties ; that A, B, and C are capable of occurring in other kinds of complex where the relation is not of the same kind as R ; and that the characteristic properties of the whole...
Page 42 - Put in abstract terms the emergent theory asserts that there are certain wholes, composed (say) of constituents A, B, and C in a relation R to each other; that all wholes composed of constituents of the same kind as A, B, and C in relations of the same kind as R have certain characteristic properties; that...
Page 50 - Has it a mind?" is never silly in the sense that it is meaningless. At worst it is silly only in the sense that it does not generally express a real doubt, and that we have no means of answering it. It may be like asking whether the moon may not be made of green cheese ; but it is not like asking whether a rich man may have no wealth.
Page 52 - It is explanatory in the sense that our knowledge of chemistry and physics makes intelligible how it is that something like the motion of molecules could play the causal role we associate with heat. Furthermore, antecedent to our discovery of the essential nature of heat, its causal role, captured in statements like (2'), exhausts our notion of it. Once we understand how this causal role is carried out there is nothing more we need to understand.
Page 44 - It is clear that in no case could the behaviour of a whole composed of certain constituents be predicted merely from a knowledge of the properties of these constituents, taken separately, and of their proportions and arrangements in the particular complex under consideration.
Page 106 - No activity of mind is ever conscious. This sounds like a paradox, but it is none the less true. There are order and arrangement, but there is no experience of the creation of that order. I could give numberless examples, for there is no exception to the rule. A couple of illustrations should suffice. Look at a complicated scene. It consists of a number of objects standing out against an indistinct background; desk, chairs, faces. Each consists of a number of lesser sensations combined in the object,...
Page 131 - Neuronal synchronization under conditions of binocular rivalry. A. Using two mirrors, different patterns were presented to the two eyes of strabismic cats. Panels (BE) show normalized cross-correlograms for two pairs of recording sites activated by the eye that won (B, C) and lost (D, E) in interocular competition, respectively. Insets above the correlograms indicate stimulation conditions. Under monocular stimulation B, cells driven by the winning eye show a significant correlation which is enhanced...
Page 105 - In psycho,analysis there is no choice for us but to assert that mental processes are in themselves unconscious, and to liken the perception of them by means of consciousness to the perception of the external world by means of the sense,organs...
