What is the structure of the brain that enables us to speak?
Broca’s Area and the motor association cortex are where speech and language production is formulated. The highest parts of the left parietal lobe are the regions where speech sound sequencing originate. Wernicke’s Area and the auditory association cortex are the seats for language comprehension. The corpus callosum enables communication between the cortical hemispheres. It is more developed and denser in women, which is why they relearn speech and language better than men do after brain compromise. Women will often have language representation in the right hemisphere in addition to the language areas in the left hemisphere. 99.9% of right-handed patients have language seated in the left hemisphere, whereas only 10% of lefties have a right-brain dominant language area. The cerebellum controls motor coordination ONLY. Other movement is represented in the primary motor cortex in the posterior portion of the frontal lobe, just anterior to the Sylvian Fissure.
