Electromechanical stimulator for presenting moving cutaneous stimuli
L. F. Walsh, P. Hantman and D. L. Blank
Recent interest in the neural processing of complex cutaneous stimuli such
as moving stimuli has necessitated more versatile stimulating devices. This
article describes the construction and application of a relatively
inexpensive instrument, utilizing equipment readily available in most
neurophysiological laboratories, which provides a variety of moving
cutaneous stimuli of selected velocities, excursions, and directions. The
electronic portion of the instrument consists of a logically controlled
varable rate integrator wired to conform to the electrical and mechanical
characteristics of a Grass P5 plug-in. This circuitry operates the
remainder of the instrument which consists of a P5 driver amplifier used to
drive the pen motor mechanism that provides the moving cutaneous stimulus.
