Higher Mental Functions of the Brain: Language

Language is a communication method that uses vocal sounds, gestures, and written words to transfer information.

The dominant hemisphere, which is usually the left hemisphere, is responsible for understanding language and speech generation, while the right hemisphere adds tone and emotional context to spoken words.

Wernicke's area, located within the temporal lobe, interprets the meaning of spoken and written language.

It receives input from the visual association area for written language or gestures and the auditory association area for spoken language.

Damage to Wernicke's area can lead to receptive aphasia, which causes difficulty in understanding spoken or written words.

Broca's area, located in the frontal lobe, produces speech.

It develops a motor pattern, which is conveyed to the primary motor area to activate the appropriate muscles necessary to produce the desired words during speech.

Injury to Broca's area leads to expressive aphasia, which hinders the ability to speak and form words.
