Broca's area (shown in red)
|Part of||Frontal lobe|
|Vein||Superior sagittal sinus|
|Anatomical terms of neuroanatomy|
Language processing has been linked to Broca's area after Pierre Paul Broca. Broca did autopsies on patients who had difficuty speaking when they were alive. He found damage to a particular area of the brain. They had lost the ability to speak after injury to the posterior inferior frontal gyrus of the brain.
Functional magnetic resonance imaging (fMRI) studies have identified activation patterns in Broca's area associated with various language tasks. However, slow destruction of the Broca's area by brain tumors can leave speech relatively intact. This suggests that, given time, its functions can shift to nearby areas in the brain.
