Angular gyrus
Gyrus angularis
Definition
Angular gyrus is a significant cerebral gyrus located on the side of the cerebral hemisphere. It has a U-shaped form. The gyrus surrounds the posterior part of the superior temporal sulcus and is positioned next to the supramarginal gyrus.
Damage to the angular gyrus on the dominant side can cause Gerstmann-Straussler syndrome. This syndrome is characterized by finger agnosia (inability to identify the fingers), right-left disorientation, acalculia (difficulty with processing numbers and calculation), and agraphia (difficulty with reading).
