Brodmann area 22

Brodmann area 22 is a region of the brain that is part of the Brodmann areas, a classification system used in neuroscience to divide the cerebral cortex into 52 distinct regions. This area is also known as the superior temporal area 22, as it is usually located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals.

Function

Brodmann area 22 is involved in several important functions of the brain. It is one of the key areas involved in auditory processing, with a particular role in the processing of speech and language. This area is also thought to play a role in social cognition, and may be involved in the perception of emotions in speech.

Clinical significance

Damage to Brodmann area 22 can result in a variety of neurological and psychiatric conditions. For example, it can lead to language disorders such as aphasia, specifically Wernicke's aphasia, which is characterized by difficulties in language comprehension. This area has also been implicated in schizophrenia, with some studies suggesting that abnormalities in Brodmann area 22 may be associated with the auditory hallucinations often experienced by individuals with this condition.
