Figure 1. Object motion sensitive (OMS) ganglion cells adapt their response to differential motion.

Figure 1

(A) Receptive field profile of an OMS (salamander Fast OFF) ganglion cell. (B) A stripe grating representing an object was projected in and around the cell’s receptive field center, while the remainder of the retina was presented with a background grating. (C) Time course of the gratings plotted along a vertical transect of the display (vertical line in panel B), illustrating the stimuli for Global Motion, Differential Motion, and Local Motion. For clarity, the number of grating bars has been reduced and only 5 seconds are shown for each stimulus condition. The transitions are marked by arrows. (D) Average firing rate of the OMS cell in (A) to 50 successive trials of a stimulus alternating between Global Motion and Differential Motion every 40 s. (E) Firing rate of another OMS cell under alternating Global and Local Motion.
