The amplitudes of the responses of over 216 neurons in areas 17 and 18 of the cat were examined as a function of spatial frequency and velocity (at the optimal spatial frequency) of moving sinusoidal gratings at the optimal direction. Multielectrode extracellular recordings were performed in isoflurane-anesthetized (0.5-1.0%), immobilized, artificially ventilated cats. Values derived from the spatial-frequency/velocity tuning plots were: optimal spatial-frequency (mean = 0.34 cycles/deg; S.D. = 0.18); spatial bandwidth (mean = 0.49 octaves; S.D. = 0.20); optimal velocity (mean = 9.61 deg/sec; S.D. = 1.44); velocity half bandwidth (mean = 0.49 deg/sec; S.D. = 0.20). These values except the optimal velocity varied considerably from neuron to neuron. Some of the cells (72/216) showed rather narrowly tuned to spatial frequency (＜0.4 octaves). The velocity tuning functions were high-pass. We conclude that our results are similar to the results obtained by the classical single unit recording technique.
