Activity pattern of the go type C cell.A, Typical example of a go type C cell with the first set of stimuli. Each pair of rasters and histograms illustrates the neuronal response to the target shown on the left. The rasters and histograms are split in two; the left side is aligned on target onset (vertical line; the horizontal bar indicates target duration), and the right side is aligned on lever release (vertical line). Only the data from correct trials were obtained. The left panel represents the neuronal activity in the color condition; the right panel represents that in the motion condition.Arrows in the stimuli indicate motion direction.go, Go trial; ng, no-go trial.Triangles in the rasters indicate fixation dimming or re-illumination (end of dim): fixation dimming in the target-aligned rasters and in the go trials of response-aligned rasters, and re-illumination in the no-go trials of response-aligned rasters. Bin width, 20 msec. B, Activity pattern of the same cell with the second set of stimuli.
