Amygdalotomy
Amygdalotomy
Amygdalotomy (pronunciation: /əˌmɪɡdəˈlɒtəmi/) is a surgical procedure that involves the disconnection of the amygdala from the rest of the brain. The term is derived from the Greek words 'amygdale' meaning 'almond' and 'tome' meaning 'cutting'.
Etymology
The term 'Amygdalotomy' is derived from two Greek words. 'Amygdale', which means 'almond', is used to describe the shape of the amygdala, and 'tome', which means 'cutting', refers to the surgical procedure of cutting or disconnecting.
Procedure
Amygdalotomy is a type of psychosurgery that was primarily used in the mid-20th century to treat severe cases of mental disorders such as schizophrenia and obsessive-compulsive disorder (OCD). The procedure involves the surgical disconnection of the amygdala from the rest of the brain. This is achieved by making a small hole in the skull and inserting a thin wire to destroy the amygdala tissue.
Effects
The amygdala is involved in processing emotions, particularly fear and aggression. Therefore, an amygdalotomy can result in changes in emotional behavior. However, the procedure has been largely abandoned due to its irreversible nature and the development of more effective and less invasive treatments for mental disorders.
