Figure 5.

Simultaneous suppression of the visual responses in the Ipc and SLu. Top, Two pairs of recording traces obtained from the repetition of the same experiment (described in the schematics above), in which a second moving dot (12 deg/s) is presented while the first moving dot (12 deg/s) is crossing the overlapped RFs of the Ipc and SLu. Note that although the suppression of responses was partial and lasted ∼500 ms, it is almost identical in each pair of recordings. Note also the characteristic double-spike discharge of the SLu neurons. Bottom, Cumulative PSTH, in the same timescale, for six repetitions of this sequential stimulation.
