Modulation of V1 Spike Response by Temporal Interval of Spatiotemporal Stimulus Sequence

Figure 4

Modulation window.

The cell of Fig. 3 is reproduced. (A) Response to S2 alone with the duration of 63 ms for inital transient response indicated with red dotted lines. (B) The duration of suppression by S1 at the position c is indicated with two green dotted lines. (C, D) Modulation window formed by the two durations in A and B in corresponding colors. Time of S1 onset is shown in a white line, interpolated across SOA. The S2-alone condition is given above for comparison in C. Note that the range of significant suppression and facilitation agrees well with modulation window. Also note that modulation is variable depending on SOA within modulation window.
