Does anybody know of any research that indicates that non-human
primates are lateralized?
I have been reviewing the literature on the posterior parietal
lobe and have found that although many investigators agree that
damage to the monkey inferior parietal lobule (IPL; area 7 or PG)
results in trimodal inattention/ unilateral neglect [this same
syndrome is readily produced in monkeys with damage in the
arcuate region of the frontal lobe] none of them
report that it occurs with damage to ONLY one side or the other.
In humans unilateral neglect almost invariably occurs with damage
to the non-dominant IPL resulting in a neglect of the LEFT
side-of-space and body. Damage to the same area on the dominant
hemisphere does not result in neglect of the RIGHT side-of-space
or body. This is easily explained by acknowledging that
Wernicke's Area occupies this position and damage here results in
I look forward to your comments; references will be greatly
