Behavioral measurements of visual sensitivity were obtained from hooded rats on a threechoice discrimination task. Increment threshold measurements reveal the occurrence ofa distinct Purkinje shift. Photopic spectral sensitivity functions for this animal have peaks at 500 and 580 nm. The results of chromatic adaptation suggest that this photopic sensitivity function results from interactions between two mechanisms with peak sensitivities near 520 and 540 nm. Along with previous behavioral and… CONTINUE READING
