Neurophysiology/sensory physiology Lect. Dr. Zahid M. kadhim

If a stimulus of constant strength is maintained on a sensory receptor, some receptor types continue to respond to the stimulus as long as its applied while others adapt, that is mean the frequency of the action potentials in their sensory nerve declines over time. This phenomenon is known as recept ...
