Paper, 'The "paralytic" secretion of saliva' by J N [John Newport] Langley

Description

Langley writes: 'It was shown by Claude Bernard that section of the chorda tympani nerve in the dog, causes, after an interval of about 24 hours, a slow “paralytic” secretion of saliva from the sub-maxillary gland; the secretion continues for several weeks, and is accompanied by a gradual diminution in the size of the gland. Heidenhain confirmed these observations, and he found further that the effect was not confined to the gland on the side of the body on which the nerve had been cut, but extended also to the corresponding gland of the opposite side of the body, so that section of either chorda tympani nerve caused a continuous secretion from both sub-maxillary glands.'
