The angular gyrus is the part of the brain associated with complex language functions (i.e. reading, writing and interpretation of what is written). Lesion to this part of the brain shows symptoms of the Gerstmann syndrome : effects include finger agnosia, alexia (inability to read), acalculia (inability to use arithmetic operations), agraphia ...
In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.

The second, the angular gyrus , arches over the posterior end of the superior temporal sulcus, behind which it is continuous with the middle temporal gyrus. In males, the inferior parietal lobule is significantly more voluminous in the left hemisphere compared to the right.
Area 39 – Angular gyrus, considered by some to be part of Wernicke's area; Area 40 – Supramarginal gyrus considered by some to be part of Wernicke's area; Areas 41 and 42 – Auditory cortex; Area 43 – Primary gustatory cortex; Areas 44 and 45 – Broca's area, includes the opercular part and triangular part of the inferior frontal gyrus
The anterior cingulate is connected to the posterior cingulate at least in rabbits. Posterior cingulate gyrus is connected with retrosplenial cortex and this connection is part of the dorsal splenium of the corpus callosum. The anterior and posterior cingulate gyrus and retrosplenial cortex send projections to subiculum and presubiculum. [16]
It is bounded caudally by the angular area 39 (H), rostrally and dorsally by the caudal postcentral area 2, and ventrally by the subcentral area 43 and the superior temporal area 22 (Brodmann-1909). Cytoarchitectonically defined subregions of rostral BA40/the supramarginal gyrus are PF, PFcm, PFm, PFop, and PFt. Area PF is the homologue to ...
BA39 encompasses the angular gyrus, lying near to the junction of temporal, occipital and parietal lobes. This area is also known as angular area 39 (H). It corresponds to the angular gyrus surrounding the caudal tip of the superior temporal sulcus. It is bounded dorsally approximately by the intraparietal sulcus.
