Jean Pierre Flourens
Marie Jean Pierre Flourens (13 April 1794 – 6 December 1867), father of Gustave Flourens, was a French physiologist, the founder of experimental brain science and a pioneer in anesthesia. Through the study of ablations on animals, he was the first to prove that the mind was located in the brain, not the heart.
James Crichton-Browne
In 1879, Crichton-Browne published his own considerations of the neuropathology of insanity making some exact predictions about the morbid anatomy of the human brain in cases of severe psychiatric disorder. He proposed that, in the insane, the weight of the brain was reduced, that the lateral ventricles were enlarged, and that the burden of damage fell on the left cerebral hemisphere. This involved an evolutionary view of cerebral localisation with an emphasis on the asymmetry of cerebral functions. He derived this from the clinical research of the French anatomist Paul Broca (1824–1880) on language centres in the brain – originally published in 1861 – and presented by Broca to the British Association for the Advancement of Science at its 1868 meeting in Norwich. The question of asymmetrical cerebral functions had been raised many years earlier by the Edinburgh phrenologist Hewett Cottrell Watson in the "Phrenological Journal". Crichton-Browne's own views on psychosis and cerebral asymmetry have been appraised by Crow, 1995 and Compston, 2007.
