Figure 4. GABA responses of isolated soma-dendritic regions of Bon and Boff bipolar cells.

Figure 4

(A) Bon type cell, characterized by glutamate hyperpolarization (“20 glut”), also hyperpolarizes robustly to GABA (“20 GABA”). (B) Boff type unit, characterized by glutamate depolarization, does not respond to GABA. (C) Boff type unit, characterized by glutamate depolarization, is depolarized by GABA. Figure conventions for voltage probe recordings are the same as described in Figure 2.
