Tarkhanova Phenomenon [. R. Tarkhanov (Tarkhnishvili, Tarkhan-Mauravi), 1846-1908, Otech. Physiolo]

Tarkhanov phenomenon

The Tarkhanov phenomenon, named after the Russian physiologist and physician Alexander Tarkhanov (1847-1919), is one of the most famous and significant discoveries in the field of physiology. It was discovered in 1902 and became the first evidence of the existence of galvanic skin response (GSR) - an electrical potential that appears on the surface of the skin when it is irritated by electric current or other stimuli.

Tarkhanov conducted a series of experiments in which he measured GSR in patients with various diseases such as migraine, epilepsy and other neurological disorders. The results of his research showed that GSR can be used to diagnose and monitor human health.

Tarkhanov’s discovery was an important step in the development of electrophysiology, a science that studies electrical processes in living organisms. It also contributed to the development of new methods for diagnosing and treating diseases.

Today, the Tarkhanov phenomenon continues to be used in medicine and other fields of science to study electrical processes in the human and animal bodies. For example, it is used in electroencephalography (EEG) to record the electrical activity of the brain and in electrocardiography (ECG) to measure heart rhythm.
