Functions of cortical local spatiotemporalfiltering ?• V1 neuron receptive field properties• How does a neuron respond to input patterns ofluminance L?–Assuming the spatial filters (receptive field weights W)are approximately identical across space, thepopulation of responses is often modeled linearly andrepresented by convolution operation:R i,j (t) = (W i x,j y L x,y (t))x,y49Wednesday, August 29, 12
