Quantitative maps of activity in area LIPv accompanying oblique up–left saccades of three different sizes. a, Average location of the endpoints of all saccade vectors (plotted relative to eye position at the start of each saccade) executed during the critical first 10 min of the [14C]DG experiment. Each symbol is from a different animal. Triangle, 10° saccades; circle and diamond, 20° saccades; square, 30° saccades. b, Reconstructed two-dimensional map of activity in the right LIPv of the animal executing 30° saccades up–left, after subtracting the Cf control map. c, Two-dimensional map of the average activity in the right LIPv of the two monkeys executing 20° saccades up–left (minus the Cf control map). d, Reconstructed two-dimensional map of activity in the right LIPv of the animal executing 10° saccades up–left (minus the Cf control map).
