Figure 11.

For three neurons (A–C, respectively), the figure shows three PSTHs summarizing the responses to three different image sets. Neuron B is the same as in Figure 1C; neuron C is the same as in Figure 1E. For each neuron, the 500 stimulus images were ranked according to the number of action potentials evoked over the whole stimulus interval including the blank between images. The top row of histograms shows PSTHs summed only across the 20 most powerful stimuli for each neuron; the middle rows sums the responses to stimuli ranked 41–70 for each neuron; whereas the bottom row sums the responses to stimuli ranked 101–150 for each neuron. The response bins are 4 ms. Note the expansion in the y-axis scale as one proceeds down the rows.
