An Automated Optical Display System for Visual Physiology Experiments.

Abstract : Control of a visual physiology overhead projection system has been achieved by an 8085 microprocessor system, with a supporting array of a-d converters, voltage-to-current amplifiers, d-a converters, and analog switches. Image position, speed of movement, direction, length of sweep and number of sweeps can all be programmed by the operator. Handshake lines send the 'start' and 'end' signals to another device which correlates nerve cell activity with stimulus movement. (Author)
