Among the various methods of stimulating the labyrinth, electric stimulation is rather neglected, apparently because it acts not only on the receptor organ but also on the afferent neuron (ganglion vestibulare, Dohlman¹ ). The possibilities of electric stimulation, however, appear not to have been completely exhausted, since generally only stimulation with a constant (direct) current is used, stimulation with faradic current yielding no definite reactions (Klestadt²). The ineffectiveness of the faradic current, however, does not exclude the possibility that the labyrinth might react on rhythmic stimulation with frequencies lower than those produced by the usual faradic apparatus. It seemed, therefore, worth while ascertaining how the labyrinth³ might react to rhythmic electric stimulation with various frequencies.

METHOD

The following arrangement (fig. 1) was used in experiments performed on cats: Circuit 1 consisted of a dry cell or storage battery, the coil of an electromagnet, a vibrating spring of variable length with . . . [Full Text PDF of this Article]
