The lateral intraparietal area (LIP) of macaques has been considered
unresponsive to auditory stimulation. Recent reports, however, indi-
cate that neurons in this area respond to auditory stimuli in the context
of an auditory-saccade task. Is this difference in auditory responsive-
ness of LIP due to auditory-saccade training? To address this issue,
LIP responses in two monkeys were recorded at two different times:
before and after auditory-saccade training. Before auditory-saccade
training, the animals had never been trained on any auditory task, but
