High Quality Content by WIKIPEDIA articles! Vernon Benjamin Mountcastle (born July 15, 1918 in Shelbyville, Kentucky) is a retired neuroscientist from the Johns Hopkins University. He discovered and characterized the columnar organization of the cerebral cortex in the 1950s. This discovery was a turning point in investigations of the cerebral cortex, as nearly all cortical studies of sensory function after Mountcastle's 1957 paper on the somatosensory cortex used columnar organization as their basis. Indeed, David Hubel in his Nobel Prize acceptance speech said Mountcastle's "discovery of columns in the somatosensory cortex was surely the single most important contribution to the understanding of cerebral cortex since Cajal". Mountcastle's interest in cognition, specifically perception, led him to guide his lab to studies that linked perception and neural responses in the 1960s. Although there were several notable works from his lab, the highest profile early paper was in 1968, astudy explaining the neural basis of flutter and vibration by the action of peripheral mechanoreceptors.
