We studied the effect of eye position on the light-sensitive,
memory, and saccade-related activities of neurons of the
lateral intraparietal area and area 7a in the posterior parietal
cortex of rhesus monkeys. A majority of the cells showed
significant effects of eye position, for each of the 3 types of
response. The direction tuning of the light-sensitive, memory
and saccade responses did not change with eye position
but the magnitude of the response did. Since previous work
showed a similar effect for the light-sensitive response of
area 7a neurons (Andersen and Mountcastle, 1983; Ander-
sen et al., 1985b), the present results indicate that this mod-
ulating effect of eye position may be a general one, as it is
found in 3 types of responses in 2 cortical areas. Gain fields
