Angular Gyrus
The angular gyrus is an area of the inferior parietal lobe of the brain which is located near the back of the head. The angular gyrus is responsible for many things including comprehension of language as well as auditory stimuli and memory retrieval. It is involved with number processing and damage to the angular gyrus can cause a person to have difficulty with math. It is also involved in visual-spatial capabilities including the perception of left and right.
