Disrupted receptive field structures in the SC of ephrin-A knockout mice. (A,B) Receptive field of a SC neuron in WT mouse. A shows peri-stimulus timing histograms (PSTH) in response to spots flashed at different locations on a 13 × 13 grid in visual space. Scale bars are 50 spikes/s (y-axis, for firing rate in each 50 ms bin) and 1 s (x-axis). Both On and Off responses were evoked within the receptive field, as indicated by the two peaks in individual PSTHs. The receptive field structure determined by the PSTHs is shown in B in a color scale (right, in spikes/s, for mean firing rate in the 1 s stimulus duration). (C–H) Example receptive fields of SC neurons in ephrin-A double (DKO) and triple KO (TKO) mice.
