Two simple thermodes for stimulating single semicircular canals have been designed in order to elicit eye nystagmus. The first, for warm stimulation, is based on the Joule effect: a silver needle is warmed up by means of a coiled nickrome wire. The temperature at the thermode tip is function of current intensity. The thermode for cold stimulation is a device in which a circulating freezing mixture cools a silver needle. The temperature at the thermode tip is proportional to the temperature of the freezing mixture.
