Carl Lashley
- studied effects of brain lesions in animals
- law of equipotentiality:
- ability for brain areas to compensate the loss of function after an injury to a particular area
- helped explain how animals could relearn previously impaired functions
- probably only pertaining to "higher order" functions, not sensory or motor functions
- law of mass action:
- size/ magnitude of lesion is proportional to the degree of loss in function
- memory loss is thus a function of lesion size, not location
