title: Electromechanical stimulator for presenting moving cutaneous stimuli.
abstract: 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.
