title: Synaptic transmission from rods to bipolar cells in the tiger salamander retina.
abstract: Synaptic transmission between rods and depolarizing bipolar cells (DBC) was studied by using simultaneous recording techniques in the living retinal slice preparation. Current injection into the rod elicited a sign-inverting, sustained voltage change in the DBC. Voltage "tails" after the termination of a bright flash were observed in dark-adapted rods and DBC but not in cones. These simultaneously recorded voltage tails were used to isolate the rod input from the cone input and to study the input-output relation of the rod-DBC synapse. Within the voltage range between 0 and -10 mV from the rod dark potential (-39 +/- 1.2 mV), the input-output relation of the rod-DBC was approximately linear, with an estimated gain of about 3.7.
