OFC cells do not exhibit motor responses related to licking or blinking. We identified the onset of a change in neural activity (if present) during the 300 ms preceding a lick or blink. Licks were examined in two time intervals: the last 1 s of the trace interval and the last 1 s of the intertrial interval (ITI). Blinks were examined in two time intervals: the last 1 s of the trace interval, and the first 1 s of the US interval. a, b, Percentage of value-coding cells for which responses before licks (a) or blinks (b) are found in both intervals examined, one interval but not the other, or neither interval. c, d, We used a high-sensitivity version of the same analysis as in a, b to obtain a broader population of cells with candidate motor responses. For each cell that had an identified response in both intervals examined, we plotted the time of response onset in the trace interval against the time of response onset in the intertrial interval (licks, c) or US interval (blinks, d). Blue, Positive value-coding cells; red, negative value-coding cells.
