[1] Electronarcosis may be used as a form of electrotherapy in treating certain mental illnesses in humans,[2] or may be used to render livestock unconscious prior to slaughter.
[4] In 1951, an American psychiatrist Hervey M. Cleckley published a paper on the results of treating 110 patients having anxiety neuroses with electronarcosis therapy.
Researchers achieved electronarcosis by applying 180 mA at a frequency of 500 Hertz to the mastoid part of the temporal bone.
[6] Electronarcosis results in a condition similar to an epileptic seizure, with the three phases called tonic, clonic, and recovery.
Modern electronarcosis is typically performed by applying 200 volts of high frequency alternating current of about 1500 hertz for 3 seconds to the animal's head.
