PERIPHERAL EFFECTOR MECHANISM OF GALVANIC SKIN REFLEX

The psycho-galvanic reflex: a pharmacological study of the peripheral mechanism.

The psycho-galvanic reflex is a decrease in the electrical resistance of the skin which occurs in response to a wide variety of stimuli. The physiological basis of this autonomic measure, known also as the galvanic skin response or electro-dermal response, has not yet been fully elucidated. There are two principal theories accounting for the phenomenon. The vascular theory, proposed by Fire (18...

Determination of Electrical Parameters for Skin during Galvanic Skin Reflex from Continuous Measurement

The skin impedance is well various and changeable rapidly, so it is not easy to measure precisely the all frequency characteristics(l). In order to measure the all frequency characteristics, there are two methods as follows. One is multi-frequency points measuring method and the other is the fast fourier transformation (FFT) method from the response in time domain. However, the former demands v...

The psycho-galvanic reflex; a comparison of A.C. skin resistance and skin potential changes.

Two closely-related electro-dermal phenomena constitute the so-called " psycho-galvanic reflex ". These are (a) a decrease in the electrical resistance of the skin, and (b) a change in the skin electromotive force in response to a wide variety of stimuli. Fere (1888) connected two electrodes on the forearm of a subject in series with a weak source of electricity and a galvanometer. He observed ...
