The dark-adaptation of single units in the frog's retina and its relation to the regeneration of rhodopsin

摘要: Abstract The dark-adaptation of single units in excised and opened frog's eyes has been recorded with such test parameters that a nervous reorganization or changes summation within the receptive fields can be excluded as explanations sensitivity increase observed. Further, using light wave-length 500 nm cone contributions after more than 40 min dark-adaptation. It thus possible to measure caused by rhodopsin rods. Because regeneration also measured, significance process for analysed. is found, log threshold linearly related rate at each instant, when expressed terms relative number quanta absorbed. Moreover, this relationship same observed between increment intensity corresponding adapting field.
