ELECTRIC SPARK STIMULATION OF THE SKIN.
Abstract
On the basis of the data it was concluded that the technique devised by Bishop for exploring the skin's sensory mechanisms is not as simple and as straightforward as it at first appeared. It was, furthermore, not possible to replicate Bishop's findings with regard to simultaneous two-point stimulation. The method of single-unit analysis of the skin is not to be discarded easily, however. Only the method of capacitor-discharge spark stimulation must be drastically revised or abandoned. In order that spark stimulation be effective it is necessary that some means be found to control both the number and spacing of the spikes. This may be achieved by some mechanical or electrical device, but the assumption of a 'single, brief shock' stimulus remains violated. The only remaining desirable change of Bishop's technique, that of avoiding actual contact with the skin, was abandoned by Bishop himself in favor of a thin wire electrode. In light of these facts, it is probably advantageous to look elsewhere for a stimulus source. There are available commercially a number of electronic stimulator devices which are capable of producing single pulses or pulse trains with a considerable degree of control. It is probable that one of these devices, with its output applied to a suitably small area, would provide the needed tool for a truly fruitful exploration of single sensory units of the skin.
