Why Is Elwood Henneman Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Elwood Henneman was an American neurophysiologist who studied the properties of vertebrate motor neurons. Biography and Research Henneman received his bachelor's degree from Harvard College in Cambridge, Massachusetts in 1937. In 1943 he finished his medical studies at McGill University in Montreal. During a research fellowship at Johns Hopkins University in Baltimore, Maryland, Henneman and colleague, Vernon Mountcastle, showed that tactile information about the extremities is represented in an orderly map in the ventrolateral thalamus of the cat and monkey. Further research positions followed, including at the Royal Victorian Hospital and at the Illinois Neuropsychiatric Institute in Chicago. At NPI, Henneman discovered that the drug Mephenesin inhibits interneurons in the spinal cord and thus causes muscle relaxation. This discovery helped lead to the development of muscle relaxant drugs.
