Physiological, Morphological and Neurochemical Characterization of Neurons Modulated by Movement

Abstract:
When a visual pattern undergoes a brief displacement, the response of the neuron depends primarily upon the size of the displacement. One measures a tradeoff between velocity and duration of motion, analogous to the reciprocal relationship between intensity and duration in the perception of a brief flash of light (Bloch's law). Characterizing the movement detector by its "impulse response" could be useful in predicting the response to arbitrary motions.
