Example of a rare multimodal locus, recorded at successive depths at which responses were observed to each of the four stimuli tested (A–D). Single sweeps all from the same animal and locus. The mechanosensory response at this locus includes a late, positive slow wave (P180). The responses to all four stimuli include long-lasting increases in multiunit activity. Note the tendency of visual and mechanical stimuli to induce bursts of corollary discharges (some marked by stars).
