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.
在虎螈的离体视网膜平铺标本中,研究了视杆细胞和视锥细胞向水平细胞(HCs)的突触输入。检测了暗适应和明适应条件下视杆细胞、视锥细胞和水平细胞的电压-强度关系、光谱敏感性和反应波形。在暗适应和明适应的视网膜中,水平细胞都接收来自视杆细胞和视锥细胞的混合输入。水平细胞中视杆/视锥细胞的相对输入取决于刺激强度和背景光照,并且因水平细胞而异。
