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 ...

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.
In order to read, information concerning the written text is sent from visual areas 17, 18, and 19 to the angular gyrus (area 39) and from there to Wernicke's area, for silent reading or, together with Broca's area, for reading out loud. This model is now obsolete. [1]
Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right. The border between the occipital lobe and the parietal and temporal lobes is characterized by different gyri: the superior occipital gyrus (also known as gyrus occipitalis superior), middle occipital gyrus (or gyrus occipitalis medius), inferior occipital gyrus (or gyrus occipitalis inferior), and ...
The angular gyrus is involved in higher processing of colors. [11] The fibers relay shape information from the fusiform gyrus to the angular gyrus in order to produce the association of colors and shapes in grapheme-color synesthesia. [11] Cross-activation between the angular and fusiform gyri has been observed in the average brain, implying ...
Diagram labeling planum temporale in green. The planum temporale is the cortical area just posterior to the auditory cortex ( Heschl's gyrus ) within the Sylvian fissure . [ 1 ] It is a triangular region which forms the heart of Wernicke's area , one of the most important functional areas for language. [ 2 ]
