In his PhD thesis, Micheal Finn notes that the article describes Caton's work on cerebral localization: 'Early verification of Ferrier's ideas [regarding cerebral localization] came from Richard Caton, who had been a medical student in Edinburgh at the same time as Ferrier, and operated in another provincial northern institution, the Royal Infirmary at Liverpool. After reading Ferrier's work he was inspired to carry out his own investigations to support the results of cerebral stmulation, by reversing the experiemental technique. Operating with primitive apparatus, Caton managed to detect electrical currents in the brains of rabbits and monkeys when certain actions or senses were in operation, in exactly those areas of the cortex that Ferrier's conclusions supposed. He presented his electrophysiological recordings to the annual meeting of the British Medical Association in 1875, and had communicated them to the Royal Society for possible publication.'
