Primary brain regions concerned with language are arrayed along and near the sylvian fissure.
Wernicke’s area at the posterior end of the superior temporal gyrus is concerned with comprehension of auditory and visual information.
Wernicke’s area projects through arcuate fasciculus to Broca’s area in the frontal lobe in front of the inferior end of the motor cortex.
The information from Wernicke’s area sent to Broca’s area is processed into a pattern of vocalization and projects the pattern via speech articulation area in the insula to the motor cortex which initiates movements of the lips, tongue, larynx to produce speech.
