A digital feedback controller application: a light response control system to reveal photoreceptor adaptation.
We present a new digital feedback application for the study of sensitivity characteristics of biological photoreceptors. The voltage response of a cell is controlled by feeding back to the stimulating LED--via the controller--the recorded membrane voltage. The light intensity changes represent the change in the sensitivity of the photoreceptors, revealing the time course of adaptation.
