'the Vice-President of the Royal Society for 1874-75, physiologist John Scott Burdon-Sanderson, demonstrated an experiment to specifically provide evidence against the presence of motor centres in the cerebral cortex [proposed by David Ferrier]. He wrote that 'although Dr. Dupuy has failed to prove that the movements he described are of the same nature with those described by Dr. Ferrier, the latter has not proved they are different.' In front of the Royal Society, he displayed experiments that appeared to prove that electrical stimulation of the cortex simply diffused to the lower centres, and that this was the cause of the motor movements Ferrier was able to display.'
