Not true. The nervous system is noisy, so successive states
are in general not causal. Of course the CNS has to eliminate
this factor.

50 gigs/day is waaay too large. Some estimates are about 1 bit/sec
of non redundant information - a CDROM can hold a lifetime at this
data rate.

Another approach is to count the number of possible brain states.
Like kinetic gas theory, the important number is the number of
identifiable states, waaay smaller than set of all possible states.

Anyone care to estimate these??
