Abstract : A complete system is described for on-line reduction of nystagmic data during vestibular bithermal caloric testing. The total eye movement in one direction for each 5-second interval is plotted in degrees by an X-Y recorder. A different symbol is used for each test condition. The operator does not have to be familiar with the computer system once it is set up since all controls to the computer are automatic. Control room operation is limited to adjustment of the gain of the raw data recorder for a calibrated eye movement and the changing of symbols on the X-Y point print plotter after each stimulation. A standard analog computer can be used for processing the data, or a special computer may be constructed. (Author)
