States of being conscious (S) can be defined on the basis of temporal
information processing. A high-frequency mechanism provides atemporal
system states with periods of approximately 30 msec to implement the f
unctional connection of distributed activities allowing the constructi
on of primordial events; a low frequency mechanism characterized by au
tomatic temporal integration sets up temporal windows with approximate
ly 3 seconds duration. This integration mechanism can be used to defin
e S. P-consciousness and A-consciousness as conceived of by Block can
be mapped onto these neuronal mechanisms.
