A NEW SKIN REFLEX-THE PALMARCHIN REFLEX

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

A new method for induction of the cough reflex.

A new method for artificially inducing the cough reflex in the unrestrained and unanesthetized dog has been devised. The present method can be utilized for testing the relative effectiveness of antitussive drugs. A monopolar electrode is in serted into the dog tracheal mucosa in such a way as to minimize surgical stress. The most successful electrical stimulation has been obtained from square-w...

The Grasp Reflex and Moro Reflex in Infants: Hierarchy of Primitive Reflex Responses

The plantar grasp reflex is of great clinical significance, especially in terms of the detection of spasticity. The palmar grasp reflex also has diagnostic significance. This grasp reflex of the hands and feet is mediated by a spinal reflex mechanism, which appears to be under the regulatory control of nonprimary motor areas through the spinal interneurons. This reflex in human infants can be r...

Hiccups: A new explanation for the mysterious reflex

The hiccup may have evolved to remove swallowed air from the stomach, which may help suckling mammals to consume more milk.

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 ...
