Fig. 6. Histograms of peristimulus distance of the neural activity of 5 unit pairs
recorded simultaneously from two electrodes spaced 250 µm apart. Each
histogram is based on 10 trials. Left, responses to AP motion; right,
responses to PA motion. Blue, responses of units recorded with the more
anterior electrode; red, responses of units recorded with the more posterior
electrode. Insets on the right indicate electrode positions for each recording
set relative to the midbrain surface.
