Task and decoding mechanisms. (A) Scheme of the task and the three oculomotor behaviors. (B) Predicting saccade direction from the population activity in LIP. The population activity of 325 neurons (red and blue curves, bottom panel) during the memory epoch was computed at the preferred eye position (derived from the fixation epoch) for two planned saccade directions (180 and 270 deg, dotted lines, bottom panel), and yielded the prediction (red and blue curves, top panel). The responses of a single neuron (red and blue dots, bottom panel) yielded the dotted probability distributions (top panel).
