Motion perception using oscilloscope display

A new type of stimulus generator has been designed and built to investigate some of the properties of the eye-brain perceptual mechanism and how it operates to perceive and interpret motion. Several time constants of the eye-brain have been measured, and their relations to other known time constants have been interpreted. Some time constants are associated with the brain and others with the retina, but all appear to interact with each other and with time constants of comparable magnitude that may occur in practical visual display systems. The application of this information to the design of practical systems is discussed briefly.
