The differentiation of speech production into only two large sections of the brain (i.e. Broca's and Wernicke's areas), that was accepted long before the advent of medical imaging techniques, is now considered outdated. Broca's Area was first suggested to play a role in speech function by the French neurologist and anthropologist Paul Broca in 1861. The basis for this discovery was the analysis of speech problems resulting from injuries to this region of the brain, located in the inferior frontal gyrus.
