galvanism

 [gal´van-izm]
1. a unidirectional electric current derived from a chemical battery.
2. the therapeutic use of such a current.
dental galvanism the production of galvanic current in the oral cavity due to the presence of two or more dissimilar metals in dental restorations that are bathed in saliva, or a single metal and two electrolytes (such as saliva and pulp tissue fluid); sometimes the current may be high enough to irritate the dental pulp and cause pain.

gal·va·nism

(gal'vă-nizm),
1. Direct current electricity produced by chemical action, as by a battery.
2. Oral manifestations of direct current electricity occurring when dental restorations with dissimilar electric potentials (for example, silver and gold) are placed in the mouth; characterized by pain or development of small areas of leukoplakia.
Synonym(s): voltaism

dental galvanism  production of galvanic current in the oral cavity due to the presence of two or more dissimilar metals in dental restorations that are bathed in saliva, or a single metal restoration and two electrolytes, saliva and pulp tissue fluid, thus producing an electrolytic cell and an electric current. When such restorations touch each other, the current may be high enough to irritate the dental pulp and cause sharp pain. The anodic restoration or areas of a restoration are subject to electrolytic corrosion.

galvanism

(găl′və-nĭz′əm)
n.
1. Direct-current electricity, especially when produced chemically. Also called voltaism.
2. Therapeutic application of direct-current electricity, especially the electric stimulation of nerves and muscle.

galvanic current - continuous one-direction electric current.
galvanic skin response - skin's response to electric stimulation. Synonym(s): electrodermal response
galvanic-faradic test - an electrodiagnostic test of muscles.

Perhaps a corpse would be re-animated; galvanism had given token of such things: perhaps the component parts of a creature might be manufactured, brought together, and endued with vital warmth.

Also discussed were the schools of vitalism--holding that living beings were fundamentally distinct from the inanimated ones because of some different physico-chemical elements or performances--and of materialism--holding that everything really existing was material in nature--, respectively, not to say anything about the creation of life, the experiments in galvanism on executed criminals, and a general vogue for automata (Mulvey-Roberts 1998: 214).
24) In this essay on Shelley, an introduction to a collection of letters, Browning compares galvanic energy to the likeliness of the "lower incitements" of a poet's soul "simulating the nobler inspiration," to achieve great poetry: "As soon will the galvanism that provokes to violent action the muscles of a corpse, induce it to cross the chamber steadily: sooner," Browning writes disparagingly (p.
5) Aldini attached metallic rods to the corpse's face and body and by the power of galvanism produced all kinds of contortions in Forster's rapidly cooling body.
Prout identified free muriatic acid (hydrochloric acid) in the gastric juice of various animals and humans after a meal and suggested that it was derived from the common salt of the blood by the force of galvanism (electricity).
He also had the highly unusual gift of putting the science in its historical and social context: he spoke of 'the history of galvanism, detailed the successive discoveries', and its possible future.
However, following a discussion between Shelley and Byron concerning galvanism and Erasmus Darwin, Mary fell into a reverie in which she saw "the pale student of unhallowed arts kneeling beside the thing he had put together," namely, a hideous corpse that he had reanimated with a "spark of life.
