Insula
Insula
Insula (/ɪnˈsuːlə/; plural: insulae) is a term used in anatomy to refer to a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes).
Etymology
The term "insula" comes from the Latin word that means "island". It was named as such due to its isolated location deep within the brain.
Function
The insula has been found to play a role in a variety of functions, including perception, motor control, self-awareness, cognitive functioning, and interpersonal experience. It is also involved in the processing of emotions and the regulation of the body's homeostasis.
