Onset latency of reward dependence and stimulus selectivity

	PRh	TE	Difference
Reward dependence	222 ms (49)	198 ms (24)	24 ms
Stimulus selectivity	123 ms (122)	105 ms (112)	18 ms
Difference	99 ms	93 ms

The latency was determined in each of the cells with significant reward dependence or stimulus selectivity (see Materials and Methods) and then averaged across the cells. The numbers in parentheses indicate the numbers of cells that showed enough strong dependence for determining the latency.
