This paper presents the results of some recent experiments in neuroscience and perceptual science that reveal the role of virtual reality in normal visual perception, and the use of television technology by the visual brain. This involves particularly the cholinergic system in the forebrain. This research throws new light on the nature of perception and the relation of phenomenal consciousness and its brain. It is directly relevant to criticisms by certain analytical philosophers of aspects of… Expand
The Neuroscientific Case for a Representative Theory of Perception
It has been urged repeatedly over the last two decades that empirical findings in neuroscience and psychology provide compelling reasons for endorsing a representative theory of perception. RichardExpand
Brain and Consciousness: The Ghost in the Machines
This paper reviews four current theories of brain-consciousness relations—classical Cartesian Dualism, the Identity Theory, Eliminative Materialism, and a new form of Substance Dualism that includesExpand
Reply to Bennett and Hacker
Hacker (B&H) continue simply to ignore the new hard evidence I presented (Smythies 2009), which can only be explained if we adopt the representative theory of perception. (This theory is not `mine',Expand
Theories of Perception and Recent Empirical Work
Theories of Perception and Recent Empirical Work by Philip Zigman Advisor: David Rosenthal In this dissertation I answer the following question: Does recent empirical work give us reason to thinkExpand
Reply to Critical Review by Professor John Smythies
Critics of PFN were not advancing any theory of perception whatsoever, but rather clarifying the concept of perception, and concepts are presupposed by the empirical investigations and theories of cognitive neuroscience. Expand
Cholinergic systems mediate action from movement to higher consciousness
Evidence is found that acetylcholine released at central sites acts through muscarinic and nicotinic receptors to initiate responses in actin and microtubule proteins, which have implications for cholinergic involvement in higher cognition. Expand
Critical Appraisal of Fish's Clinical Psychopathology Signs and Symptoms in Psychiatry (Third Edition)
AbstractThe aim of authors are to highlight the errors in the third edition of Fish's Clinical Psychopathology and inform its readers to use their discretion before accepting the edited version asExpand


Space, Time and Consciousness
This paper describes a new theory of consciousness based on previous work by C.D. Broad, H.H. Price, Andrei Linde and others. This hypothesis states that the Universe consists of three fundamentalExpand
An empirical refutation of the direct realist theory of perception
There are currently two main philosophical theories of perception ‐ Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter formsExpand

An exposition of the theory and a review of the associated data are provided, and it is concluded that some of the issues may remain intractable unless appropriate neuroscientific investigations are carried out. Expand
Binding, spatial attention and perceptual awareness

  • 2003
Findings from the study of abnormal binding — for example, after stroke — and unusual binding — as in synaesthesia — might help to understand the cognitive and neural mechanisms that contribute to solving this 'binding problem'. Expand
Requiem for the identity theory
This paper examines the impact that recent advances in clinical neurology, introspectionist psychology and neuroscience have upon the philosophical psycho‐neural Identity Theory. Topics coveredExpand
The experimental evidence for subjective referral of a sensory experience backwards in time: reply t
Our experimental investigations of cerebral neuronal activities that might uniquely be part of the processes that elicit a conscious sensory experience, produced evidence for the hypothesis that twoExpand
How direct is visual perception?: Some reflections on Gibson's “ecological approach”
The thesis that the postulation of mental processing is unnecessary to account for their perceptual relationship with the world is examined; that if the authors describe the environment in the appropriate terms they see that visual perception is direct and requires only a selection from information present in the ambient light.

The Neurological Approach to the Problem of Perception
I much appreciate the honour of being invited to deliver the first Manson lecture, which, its founder has laid down, is to be devoted to the consideration of some subject of common interest toExpand
Acetylcholine in cortical inference
A theory of cholinergic modulation in perceptual inference is developed, suggesting that ACh levels reflect the uncertainty associated with top-down information, and have the effect of modulating the interaction between top- down and bottom-up processing in determining the appropriate neural representations for inputs.
