Modulation of V1 Spike Response by Temporal Interval of Spatiotemporal Stimulus Sequence
The mean indices were 91.23±18.40 and 96.28±15.24, respectively. These means are significantly less than 100% (Wilcoxon signed-rank test, all p<10−7). The proportions of significant suppression and facilitation (black bars) were 21.24 and 3.72% (A), and 9.44 and 5.07% (B), respectively. Note that suppression was more frequent than facilitation, for both collinear and parallel configurations, but this difference was larger for collinear condition.
