The combined changes between electrodermal resistance and electrodermal potential make up electrodermal activity. Galvanic skin resistance (GSR) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are normally placed about an inch ...
The Galvani potential difference is not directly measurable using voltmeters. The measured potential difference between two metal electrodes assembled into a cell does not equal the difference of the Galvani potentials of the two metals (or their combination with the solution Galvani potential) because the cell needs to contain another metal-metal interface, as in the following schematic of a ...
The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...
Galvanic (after Luigi Galvani) may refer to: Galvanic anode; Galvanic bath; Galvanic cell; Galvanic corrosion; Galvanic current; Galvanic isolation; Galvanic potential; Galvanic series; Galvanic skin response; Galvanic vestibular stimulation; Galvanism; Galvanization; Operation Galvanic, World War II attack which included the Battle of Tarawa
Johann Georg Sulzer. Galvanic phenomena were described in the literature before it was understood that they were of an electrical nature. In 1752, when the Swiss mathematician and physicist Johann Georg Sulzer placed his tongue between a piece of lead and a piece of silver, joined at their edges, he perceived a taste similar to that of iron(II) sulfate.
Sympathetic Skin Response or Galvanic Skin Response [22] is defined as the variation in skin electrical potential resulting from sympathetic sudomotor outflow at very low levels although this is not a test of “sweat” function, it is often included in this category as a measure of sudomotor activity.

Among his numerous contributions was the discovery of the skin galvanic reflex (1889). However, Tarkhnishvili's most significant contribution was the discovery of the influence of X-rays on the central nervous system, animal behavior, the heart and circulation, and embryonic development (1896-1903).
