Onset latency: fixation vs. behavior data set #1 vs. #2; #4 vs. #5	91 + 83 = 174	9 + 13 = 22	152
Offset latency: fixation vs. behavior data set #4 vs. #5	83	21	62

“Study/Data Set No.”: number of neurons grouped by experimental condition in each data set. Rightmost column: the median and minimum number of trials across all cells used in each experiment to construct PSTHs and calculate onset and offset latencies. “Analysis”: summary of included subsets contributing to onset and offset latency analyses performed here.
