In 1864, Bain prompted David Ferrier to spend some time in their laboratories.
On returning to Scotland, David Ferrier graduated in medicine in 1868 at the University of Edinburgh.
David Ferrier wanted to test Jackson's idea that epilepsy had a cortical origin, as it was suggested by his clinical observations.
Coincidentally, David Ferrier had received a proposal to direct the laboratory of experimental neurology at the Stanley Royd Hospital, a psychiatric hospital located in Yorkshire.
David Ferrier had succeeded in demonstrating, in a spectacular manner, that the low intensity faradic stimulation of the cortex in both animal species indicated a rather precise and specific map for motor functions.
David Ferrier was able to demonstrate that the high-intensity stimulation of motor cortical areas caused repetitive movements in the neck, face and members which were highly evocative of epileptic fits seen by neurologists in human beings and animals, which probably were due to a spread of the focus of stimulation, an interpretation very much in line with Jacksonanian thought.
David Ferrier was the first physiologist to make an audacious transposition of cortical maps obtained in monkeys to the human brain.
Jackson and David Ferrier were present at the first operation performed by Godlee on 25 November 1884.
In 1892, David Ferrier was one of the founding members of the National Society for the Employment of Epileptics, along with Sir William Gowers and John Hughlings Jackson.
David Ferrier died of pneumonia on 19 March 1928 in London.
David Ferrier left a widow, Constance, and a son and daughter.
Together with his friends Hughlings Jackson and Crichton-Browne, David Ferrier was one of the founders of the journal Brain in 1878, which was dedicated to the interaction between experimental and clinical neurology and is still published today.
In that year David Ferrier delivered the Goulstonian Lecture to the Royal College of Physicians on "The localisation of cerebral diseases".
