Functional Areas of the Brain

Area	Lobe	Function
Auditory Association Area	Temporal	Makes sense of sounds; processes complex auditory information
Auditory Cortex	Temporal	Detects sound quality
Motor Association Cortex	Frontal	Coordinates movements including limb and lip motion
Prefrontal Cortex	Frontal	Controls high-order thinking and emotion
Primary Motor Cortex	Parietal	Initiation of all voluntary actions
Primary Somatosensory Cortex	Parietal	Receives tactile information from body; controls voluntary reactions to this information
Sensory Association Cortex	Parietal/Insula	Processes multiple body senses (touch, smell, taste)
Speech Center (Broca's Area)	Frontal	Speech production and articulation; controls movement of mouth
Visual Association Area	Occipital	Recognition of what eye and visual cortex see
Visual Cortex	Occipital	Receives sight messages from eyes
Wernicke's Area	Temporal	Language comprehension; processes auditory signals received from Auditory Association Area and Auditory Cortex

The center for speech is in the left hemisphere of the cerebral cortex. Two areas known as Wernicke's area and Broca's area are involved in storing information related to speech. Wernicke's area stores information needed for arranging the words of a learned vocabulary into meaningful speech. Broca's area stores information needed for speech production. Broca's area is responsible for programming the motor cortex to move the tongue, lips and speech muscles to articulate words.
