Rollett [1876], along with microscopical examination of the tendon nerve-endings, made search for evidence of tendon reflexes and obtained none. Sassa, however [1921], though noting absence of knee-jerk and ankle-jerk, elicited in the winter frog at low room temperature a proprioceptive reflex in the flexor muscle scmitcndinosus/ and Langelaan has noted [1901, see further Alten- burger, 1926] seeing the tendon reflex in "very lively" frogs in late winter. The defaulting of extensor stretch reflexes in the frog, whereas in other laboratory types they are best marked of all the stretch reflexes, has been attributed [Sassa, 1921] to the flexor character of the reflex limb-posture in the frog, the flexor tonus favouring the myotatic reflexes of the flexors but not of the extensors." Sherrington Sir Charles Scott Sherrington (1857-1952) was a British neurophysiologist. His experimental research established many aspects of contemporary neuroscience, including the concept of the spinal reflex as a system involving connected neurons (the "neuron doctrine"), and the ways in which signal transmission between neurons can be potentiated or depotentiated. Sherrington himself coined the word "synapse" to define the connection between two neurons. He was awarded the Nobel Prize in Physiology or Medicine in 1932 (along with Edgar Adrian). In addition to his work in physiology, Sherrington did research in histology, bacteriology, and pathology. Bestandsnummer des Verkäufers 68792
