Figure 8.

Probe contrast dependence of the cueing effects in the RT task. A, Normalized population PSTHs at 5 probe contrasts, respectively, for the cue-on and cue-away conditions (all normalized to the peak response in the 80% probe contrast condition, n = 17 V1 sites); 280 trials each condition. The cue-to-probe SOA was 150 ms for the data shown here. B, Cue-induced V1 modulation as a function of probe contrast. C, D, The behavioral data. Error bars indicate ± SEM. *p < 0.05. Refer to Figure 7 for more details.
