SYSTEM FOR RECORDING STIMULI AND SUBJECTS' RESPONSE

摘要

A system to integrate and synchronize a plurality of signals for recording on a destination video recording device (14) and/or for display on a monitor (21). The plurality of signals represent the response of a respective of a plurality of test subjects to certain stimuli. A plurality of test subjects view an audio-visual display (11) from an audio-video source, such as a video cassette recorder (9), while respective EEG responses (2) to the audio-video display are measured. The respective EEG responses (2) are sent to respective processors (3) and converted to graphical representations of the EEG signals. The graphical representations of the EEG signals (20) and a signal from the source audio-video device (12) are sent to respective destination VCRs (14) and/or a respective destination audio-video recording device that records the data from both sources. The respective destination audio-video devices can send respective composite signals to a respective VCR (14) and/or a respective destination monitor (21) to record and/or display the synchronized signals from the source audio-video recording device and the graphical representation of the EEG signals simultaneously. The respective destination VCRs and respective destination monitors can also record and/or display output and control data such as the time and date of the test.
