What is the angular and supramarginal gyrus?

The angular gyrus is a portion of the parietal lobe of the brain. It is one of the two parts of the inferior parietal lobule, the other part being the supramarginal gyrus. It plays a part in language and number processing, memory and reasoning 1.

What does the angular gyrus mean in psychology?

a ridge along the lower surface of the parietal lobe of the brain, formed by a junction of the superior and middle temporal gyri. This region has been proposed as the key area of reading and writing function.

Are there two angular gyrus?

The two angular gyri are connected via the isthmus of the corpus callosum (a large white matter tract that connects the two cerebral hemispheres at the midline) and dorsal splenium (the most posterior region of the body of the corpus callosum).

What is the role of angular gyrus?

The angular gyrus is a region of the brain in the parietal lobe, that lies near the superior edge of the temporal lobe, and immediately posterior to the supramarginal gyrus; it is involved in a number of processes related to language, number processing and spatial cognition, memory retrieval, attention, and theory of …

What causes damage to the angular gyrus?
