THE CLASSIFICATION OF GALVANIC SKIN REFLEX AFFERENT FIBERS

Independence of the galvanic skin reflex from the vasoconstrictor reflex in man.

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 ...

Gentle mechanical skin stimulation inhibits the somatocardiac sympathetic C-reflex elicited by excitation of unmyelinated C-afferent fibers.

The effects of gentle mechanical skin stimulation on reflex discharges in cardiac sympathetic nerve evoked by somatic afferent stimulation were studied in anesthetized rats. Mass discharges were recorded from cardiac sympathetic efferent nerve while somatocardiac sympathetic A- and C-reflexes were elicited by single electrical stimuli to myelinated A- and unmyelinated C-afferent fibers of the t...

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...

Nature and significance of the reflex connections established by large afferent fibers of muscular origin.

A CENTRIPETAL impulse volley traversing the myelinated afferent fibers in the nerve to a given muscle, or fraction thereof, is known to provoke a variety of reflex effects (4). By direct, or monosynaptic impingement upon motor nuclei it promotes the discharge of homonymous motoneurons, which is to say motoneurons supplying that given muscle or muscle fraction; it facilitates the response of mot...
