Abstract
Conscious perception, like the sight of a coffee cup, seems to involve
the brain identifying a stimulus. But conscious input activates more
brain regions than are needed to identify coffee cups and faces.
It spreads beyond sensory cortex to frontoparietal association areas,
which do not serve stimulus identification as such. What is the role
of those regions? Parietal cortex support the first person perspective
on the visual world, unconsciously framing the visual object stream.
Some prefrontal areas select and interpret conscious events for executive
control. Such functions can be viewed as properties of the subject,
rather than the object, of experience the observing self that
appears to be needed to maintain the conscious state.
