1873

David Ferrier conducts stimulation and ablation experiments of motor cortex in dogs and monkeys at Yorkshire’s West Riding Lunatic Asylum, continuing, and refining the findings of Fritsch and Hitzig (e.g., that animals higher on phylogenetic scale are more impaired by motor-cortex lesions than lower cousins). Ferrier extended their research to isolation of sensory cortical areas, where Ferrier was accurate for hearing and smell but not for sight and skin senses. Publication of Ferrier’s The Functions of the Brain in 1876 and Localization of Cerebral Disease in 1878 (Finger, 162-167).
