Carrier frequency discrimination performance for three spike train classifiers. Performance for the phase-only classifier (black circles) closely matched that of the full spike train classifier. Performance was substantially poorer for the rate-only classifier (gray circles). Performance expected by chance (based on the number of stimuli comprising each CFF) for each neuron is indicated by ordinate value of the thin black circles. Thus data from each cell are represented by a vertically aligned trio of circles: one representing performance of the phase classifier (black), one representing performance of the rate classifier (gray), and one representing classifier performance expected by chance (thin). The horizontal location of each trio reflects the performance of the full spike train classifier.
