SD cells may encode viewing paths. (Left) Taking all recorded ensembles (n = 10), prediction accuracy (the predicted–actual direction circular correlation coefficient) improved as the number of neurons in the ensemble increased. The best-fit line is in black. (Right) Predicted saccade direction is plotted against actual saccade direction in this histogram for an ensemble of seven neurons (391 saccades). Warmer colors represent a greater number of saccades, and the white dashed line corresponds to exact prediction. Two cycles are shown for clarity.
