| Abstract: | An inexpensive computer-driven bipolar stimulator is described. The device produces variable-duration bipolar click stimuli for use in auditory evoked response studies, but is applicable to other research. The unit is driven directly from the digital input/output interface of the averaging computer, and temporal parameters are completely controlled by the machine. |
