Average responses from the three populations of cells. A, The Vm traces are the population synaptic responses at the highest velocity-acceleration (1300°/sec; 7.8 × 105°/sec2) and at the resting Vm. The population PSTH (bin size, 1 msec) was constructed by adding the spike counts from the same responses. B, Synaptic responses were scaled to their peaks and superimposed to illustrate differences in shape and time course. PSTHs are partially overlapped to illustrate the sequential output of the layers after sensory activation.
