[3] The angular gyrus is the part of the brain associated with complex language functions (i.e. reading, writing and interpretation of what is written).

[10] V. S. Ramachandran, and Edward Hubbard published a paper in 2003 in which they hypothesized the angular gyrus to play a role in understanding metaphors.

This has not been studied in detail but we have seen disturbances in the Bouba/Kiki effect (Ramachandran & Hubbard, 2001a) as well as with proverbs in patients with angular gyrus lesions.

[11]The fact that the angular gyrus is proportionately much larger in hominids than other primates, and its strategic location at the crossroads of areas specialized for processing touch, hearing and vision, leads Ramachandran to believe that it is critical both to conceptual metaphors and to cross-modal abstractions more generally.

Research by Krish Sathian (Emory University) using functional magnetic resonance imaging (fMRI) suggests that the angular gyrus does not play a role in creating conceptual metaphors.

[14][15] Functional imaging has shown that while other parts of the parietal lobe bilaterally are involved in approximate calculations due to its link with spatiovisual abilities, the left angular gyrus together with left Inferior frontal gyrus are involved in exact calculation due to verbal arithmetic fact retrieval.

[18][19] It may allocate attention by employing a bottom-up strategy which draws on the area's ability to attend to retrieved memories.

[25] Stimulation of the left angular gyrus in one experiment caused a woman to perceive a shadowy person lurking behind her.
