Comparison of modulations in V1 induced by single cue versus double cues in the fixation task. A, Normalized population PSTHs (10 ms bins) in Monkey MH from one recording session interleaving cue-on, cue-away, and cue-both conditions (50 trials per condition, n = 27 recording sites; cue-to-probe SOA = 150 ms, probe contrast = 10%). B, Quantification of the cue-induced neural response modulations (all relative to the cue-away condition) in the four time windows delimited by colored bars in A. A time window before probe onset (−120 to −50 ms) is included here to cover the responses to the cue. Error bars indicate ± SEM across recording sites. **p = 0.003 (two-sided t test for whether the modulations in the cue-on and cue-both conditions are significantly different from each other).
