Ferrier succeeded in a spectacular way to prove that the low intensity of Faraday stimulation of the cortex provides a fairly precise and specific map for motorial functions. The same areas caused the loss of functionality after being damaged by the stimulation. Ferrier was also able to prove that the repetitive motions in the neck, face and limbs, strongly reminding of epileptic attacks that neurologists noticed in humans and animals, were caused by high intensity stimulation of motorial cortical areas. This likely as a result of the distribution of the focus of the stimulation, an interpretation strongly in line with the Jacksonan idea.
These and other studies following the same line, resulted in international fame for Ferrier and ensured his fixed status as one of the greatest experimental neurologists. He was elected as a Fellow of the Royal Society in June 1876 at age 33.
