The subject receives conceptual information from a display screen (1) and background stimuli from a transducer (8). Electrodes (3) pick up the evoked brain waves and pass them to amplifiers (4) and analog-digital converter (5) to condition them for analysis in a computer system (6, 7). The results are then stored on computer disk memory (9) and used to control a peripheral device (10) through an interface (10a).
