These experiments were performed to measure the spatiotemporal receptive fields of cortical cells. The data were obtained with extra-cellular recordings from the primary visual cortex of anesthetized adult cats. Visual stimuli were one-dimensional white noise (random bars) aligned to the preferred orientation of each cell and two-dimensional stimuli (natural images, natural phase, and random phase). We have previously used spike-triggered average and spike-triggered covariance to analyze these data. They can be used to test other methods for analyzing the stimulus-response relationship of visual cortical neurons.
Experimental procedures are described in the following papers:
Format of the data
Stimulus files are in Matlab format. Neuron responses are in binary files listing the spike times. Details are described in file crcns-pvc2-readme.pdf. Total file size is about 73 MB (compressed), 95 MB uncompressed.
