A bipolar electrode is described, designed to obtain improved reflex responses from the tensor tympani muscle by electric stimulation of the under surface of the tongue, d.c. generator, 7-9 V d.c. In comparison with the previous unipolar method of stimulation the responses under oscilloscopic analysis appear very constant and of greater size. The latency, in normal subjects, is 117 msec.
