Method Intracellular responses from photoreceptors R1-6 in the intact retina of the blowfly ( Calliphora vicina) were recorded to calibrate the effective intensity of illumination of each cell by counting quantum bumps and to measure membrane resistance by injecting randomly modulated current via a single electrode-switched clamp.
Comments This value is also ATP cost for a graded signal in a photoreceptor, or for spike coding.
