Figure 9. Crossover excitation is displayed by many ganglion cells in the rabbit and mouse retinas.

Figure 9

A, raster plots and peristimulus time histograms (PSTHs) of an OFF and an ON ganglion cell in the rabbit retina recorded with a multielectrode array. Blockade of GABAergic inhibition with PTX (100 μm) unmasks robust responses of opposite polarity. B, raster plots and PSTHs of an OFF and an ON ganglion cell in the wild-type mouse retina recorded with a multielectrode array. Similar to the rabbit, blockade of GABAergic inhibition with PTX unmasks robust responses with polarity opposite to that of the cells’ classic centre-mediated responses. Light intensity of green stimulus = 0.18 Rh* rod−1 s−1.
