Examples of activity of two V1 single cells that present a significant reduction of their visual responses latency during the bimodal visuo-auditory conditions (AV). A and D represent rasters of the cells activity in the visual-only condition, while B and E show the activity of the same cells in the visuo-auditory conditions. The red dots indicate the time at which the monkey is making a saccade toward the visual target. C and F represent the response peristimulus time histogram to visual (blue) or visuo-auditory (red) stimuli. In both cells, the AV response latency is shorter compared to the V-only condition.
