Thought mental functions were in corpus alba. MENU D. Generalists Flourens used the experimental method to try to refute the claims of the phrenologists. He was the first to employ the term equipotentiality Hughlings Jackson was resistant to localization. He approached the problem from the idea of level of construction rather than specific localization. His ideas were too complex for the time.
Many functions are the result of activity of the whole brain.
Categoric behavior - highest level, dependent upon mass of the brain rather than specific localization. Found size of damage more predictive of effect than specific location. Mass action Specific function is shared by all neurons in association cortex. Equipotentiality - All neurons within a sensory area share equally in determining function. Investigated expressive language area in patient named Tan.
