SUMMARY AND CONCLUSIONS
1. The cortex of the inferior parietal lobule (IPL) contains neu-
rons whose activity is related to saccadic eye movements. The
exact role of the IPL in relation to saccadesremains, however,
unclear. In this and the companion paper, we approach this prob-
lem by quantifying many of the spatial and temporal parameters
of the saccade-related(S)activity. Theseparameters have hitherto
been largely unstudied.
2. The activity of single neurons was recorded from Macaca
mulatta monkeys while they were performing a delayed-saccade
task. The analysis presented here is based on 161 neurons re-
