SUMMARY AND CONCLUSIONS
1. The lateral intraparietal area (LIP) of the posterior parietal
cortex lies within the dorsal cortical stream for spatial vision and
processes visual information to plan saccadic eye movements. We
investigated how LIP neurons respond when a monkey makes sac-
cades to the remembered location of sound sources in the absence
of visual stimulation.
2. Forty-three (36%) of the 118 neurons sampled showed sig-
nificant auditory triggered activity during the memory period. This
figure is similar to the proportion of cells showing visually trig-
