Shapes of the firing rate patterns in neurons whose rates differed across the “In” state defined by 3 relative duration bins, irrespective of trial type. The abscissa provides the change in rate from Bin 1 to Bin 2, while the ordinate provides the change in rate from Bin 2 to Bin 3. The rate changes were normalized by the maximum change, such that all points fall along the unit square. Points in quadrants 1-4 correspond to a positive ramp, a peak, a negative ramp and a dip, respectively. Figure from Matell,M.S.
