[A minicomputer system that extracts evoked responses from the E.E.G]

EVøQ is a minicomputer system that enables one to extract average evoked responses from the E.E.G. from a large number of analog channels, and can, therefore, be oriented towards a topographic study of the responses. It allows high-frequency sampling of the signal, in order to make possible a study of the brain stem evoked responses. This system consists of three programs: a configuration-editor which allows a pre-configuration of several kinds of experiments; an acquisition program, of monitoring, calibration, signal processing and automatic control of the stimulators; finally, a management and processing program of the resulting files.
