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.
Human brain
In 1316, Mondino de Luzzi's "Anathomia" began the modern study of brain anatomy.
Niccolò Massa discovered in 1536 that the ventricles were filled with fluid. Archangelo Piccolomini of Rome was the first to distinguish between the cerebrum and cerebral cortex. In 1543 Andreas Vesalius published his seven-volume "De humani corporis fabrica". The seventh book covered the brain and eye, with detailed images of the ventricles, cranial nerves, pituitary gland, meninges, structures of the eye, the vascular supply to the brain and spinal cord, and an image of the peripheral nerves. Vesalius rejected the common belief that the ventricles were responsible for brain function, arguing that many animals have a similar ventricular system to humans, but no true intelligence.
