A few words of thanks would be greatly appreciated.

Broca's area - Definition


Broca's area designates one of the three regions of the brain responsible for language in humans (the second is Wernicke's area, and the third is situated at the parietal level). It owes its name to the French surgeon, Paul Broca, who discovered it in the 1860s. It is because of this cerebral area that humans are able to have articulated language, as it controls the lips, the tongue, the pharynx, the larynx and the palate. When there is an affliction of this area of the brain, it is known as Broca's aphasia: the patient expresses himself poorly but understands all that is communicated to him.
