Abstract

Is consciousness based in prefrontal circuits involved in cognitive processes like thought, reasoning, and memory or is it based in sensory areas in the back of the neocortex? The no-report paradigm has been crucial to this debate because it aims to separate the neural basis of the cognitive processes underlying post-perceptual decision and report from the neural basis of conscious perception itself. However, the no-report paradigm is problematic because, even in the absence of report, subjects might engage in post-perceptual cognitive processing. Therefore, to isolate the neural basis of consciousness, a no-cognition paradigm is needed. Here, I describe a no-cognition approach to binocular rivalry and outline how this approach can help to resolve debates about the neural basis of consciousness.

Keywords: consciousness; frontal; global workspace; higher order; perception; rivalry.
