One hour in the Global Neuronal Workspace of an ASSC President
Lionel Naccache
Paris Brain Institute, President-Elect ASSC, France
After a brief synthetic introduction to the GNW theoretical framework, I will address findings, questions and hypotheses related to the following three main topics: conscious access, conscious states and conscious stream. What is conscious access (and what it is not)? When and where does it occur in the brain? Are there neural signatures common to all conscious states ? What is the minimal core size of a GNW ? Could conscious stream be structured as a (non-dualistic) ‘Inner Cinema’ beyond the limited case of perception? In other words, could conscious stream be structured as a succession of discrete moments interspersed with brief non-conscious periods that are transformed into a subjective experience of continuity through a high-level filling-in and kinematic process? This journey into cognitive neuroscience of consciousness will include a substantial neurological ‘detour’ into various severe Disorders of Consciousness (DoC) encompassing epilepsy, but it will also touch on hypnosis, functional neurological disorders, sleep, mind wandering and mind blanking.
