A system to integrate and synchronize a plurality of signals for recording on a destination video recording device and/or for display on a monitor. The plurality of signals represent the response of a test subject to certain stimuli. A test subject views an audio-visual display from an audio-video source, such as a video cassette recorder, while an EEG response to the audio-video display is measured. The EEG response is sent to a processor and converted to a graphical representation of the EEG signal. The graphical representation of the EEG signal and a signal from the source audio-video device are sent to a destination VCR and/or a destination audio-video recording device that records the data from both sources. The destination audio-video recording device can send a composite signal to a destination VCR and/or a destination monitor to record and/or display the synchronized signals from the source audio-video recording device and the graphical representation of the EEG signal simultaneously. The destination VCR and destination monitor can also record and/or display output and control data such as the time and date of the test.
