Figure 8.

Population responses of MT units to moving (dashed curves) and stationary (solid curves) stimuli. For each unit, spontaneous activity was subtracted, and PSTHs were normalized by the peak response to moving dots. PSTHs were then averaged across neurons. Thick curves represent the subpopulation of MT units with SMRR > 0.33. Thin curves are the average of units with SMRR < 0.33. A, Population responses for all of the multiunit recordings (n = 76). B, Population responses for all of the single units (n = 42).
