"Global workspace theory
My colleagues and I introduced the theory of a Global Neuronal Workspace
(GNW) as a putative neurobiological architecture capable of accounting
for cognitive and neuroscience observations on unconscious and
conscious processing (Dehaene & Naccache, 2001)...... ....The hypothetical neurobiological mechanism for global availability is a set
of large cortical pyramidal cells with long-range excitatory axons (GNW
neurons), together with their relevant thalamo-cortical loops. These cells are
present throughout the human cortex, yet they are particularly dense in prefrontal,
cingulate, and parietal regions. They form a long-distance network
that interconnects associative cortical areas and allows them to flexibly recruit,
in a top-down manner, virtually any specialized area. Through their numerous
reciprocal connections, GNW neurons are thought to amplify and maintain
a specific neural representation for an arbitrary duration, thus keeping it “on
line” or “in mind”
