| summary | It has been proposed that one key step for solving the mystery of consciousness is to locate the neural correlates of consciousness (NCC). The paradigms for revealing the NCC have commonly applied the contrast between conditions with and without conscious perception. I argue that such contrast does not exclusively reveal the neural processes directly related to conscious experience of the target but also the prerequisites for and the consequences of conscious perception. Therefore, understanding the neural bases of conscious experience requires the NCC to be experimentally distilled from these confounding processes. We ourselves have designed an experimental paradigm where conscious perception is modulated either by sensory evidence or by prior knowledge. The logic of our approach is the following: although conscious perception could be modulated through these two different prerequisite processes, conscious experience and thus the NCC should be the same in both cases. Our aim has been to use this paradigm to empirically test some proposed markers of NCC. In particular, we have tested the idea that local category specific gamma band responses are a marker of NCC. We have also tried to test the hypothesis that long-range synchrony is the crucial mechanism for conscious perception.
Le Dr. Aru parlera sur le rapport entre activité cérébrale (oscillations gamma), et conscience perceptive. Il parlera également sur ses études de connectivité (synchrony) de sources en MEG. |
