Abstract The von Economo neurons (VENs) are large
bipolar neurons located in frontoinsular (FI) and anterior
cingulate cortex in great apes and humans, but not other
primates. We performed stereological counts of the VENs
in FI and LA (limbic anterior, a component of anterior
cingulate cortex) in great apes and in humans. The VENs
are more numerous in humans than in apes, although one
gorilla approached the lower end of the human range. We
also examined the ontological development of the VENs in
FI and LA in humans. The VENs first appear in small
numbers in the 36th week post-conception, are rare at birth,
and increase in number during the first 8 months after birth.
There are significantly more VENs in the right hemisphere
