1. A system for performing a medical examination comprising:

  • means for presenting a series of sensory stimuli for perception by a patient;

    means for generating electrical signals representing said patient'"'"'s evoked potentials in response to said sensory stimuli;

    means connected to said generating means for detecting said signals;

    means connected to said detecting means for amplifying said signals;

    means connected to said amplifying means for recording data representative of said signals;

    means connected to said recording means for measuring said data; and

    means connected to said measuring means for synchronizing the presentation of said series of sensory stimuli with the rate of sampling said evoked potential signals by generating interrupt request signals for initiating and conducting said sampling.
