Abstract
Microelectrode recordings of single cells were obtained from the visual cortices of twenty acutely prepared curarized cats. A 500 msec light stimulus was presented for 150 trials at inter-flash intervals of 1.3, 2.0, 2.5, 3.2 and 4.0 seconds. The post stimulus time histograms of cells responding with an accelerated firing to stimulus onset encoded the inter-stimulus interval by an increased firing during the second of three 166 msec periods during the stimulus. The firing at light offset and after did not encode inter-stimulus intervals.
