The Relationship Between Amplifiers and Photoreceptors

Adaptation memory in photoreceptors: different mechanisms in rods

To estimate the possible relationship between ''adaptation memory'' and the activation rate of the phototransduction cascade, we analyzed the behavior of the initial phase of the response.
