Figure 4.

Data from one cell for all directions tested. A, The time course of the firing rate for each direction is shown. Coherent motion began at time = 0 ms. Eight directions relative to the preferred direction were tested for each cell (0°, ±22.5°, ±45°, ±90° and 180°). The same null direction (180°) data appear at the top and bottom of each plot. B, Time course of DP for each direction. A broad peak in detect probability is visible for directions near the preferred direction during the coherent motion portion of the trial. C, Time course of RTC for each direction tested. A broad peak in reaction time correlation is seen for directions near the preferred direction. The gray areas in B and C are beyond the median reaction time for that direction and were excluded from analysis.
