There are numerous documented cases of microcephalics with normal mental
functionality; a lot of the human brain is redundant, something that is
mentioned as a performance boosting factor in "5HC". This can be read
about in Carl Sagan's book _Broca's Brain_, somethign along with Ray
Kurzweil's book would have been available to Wolfe during the 70s.

Measuring raw switching events per second is misleading. The 10^11
neurons in the brain might change state 20-30 times a second each, for
2.5 2.5 x 10^12 switching events a second. However, almost 10 years ago,
Pentium processors with 3.3 million transistors were running at 100
megahertz, for 3.3 x 10^14 switching events a second, and just consuming
a few watts.

Ray Kurzweil writes on this sort of comparison extensively; at current
rate of development, computers will approach the complexity of the human
brain in terms of informational and interconnected capacity in about 30
years.
