Synaptic inputs from rods and cones to horizontal cells in the tiger salamander retina.
Synaptic inputs from rods and cones to horizontal cells (HCs) were studied in the flatmounted isolated retinas of the tiger salamander. Voltage-intensity relations, spectral sensitivities and response waveforms of the rod, the cone, and the HC under dark- and light-adapted conditions were examined. HCs receive mixed inputs from rods and cones in both dark- and light-adapted retinas. The relative rod/cone input in HCs depends on the intensity of stimulus and background illumination, and it varies from HC to HC.
