Figure 30. Retinal ganglion cells are influenced by current injection into horizontal cells. Horizontal cells were penetrated with intracellular electrodes while extracellular spikes were recorded from ganglion cells close to the horizontal cell recording site. The firing rate of an ON-center ganglion cell was reduced by hyperpolarizing current injection, and increased by depolarizing currents (red, above). The firing rate of an OFF-center ganglion cell was increased by hyperpolarizing currents, and slightly decreased by depolarizing currents (blue, below). The actions mimicked ganglion-cell surround responses. The illustration is taken from Mangel, 1991 (290).
