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 and cognition. It is Brodmann area 39 of the human brain.

Use in language

Geschwind proposes that written word is translated to internal monologue via the angular gyrus.

V. S. Ramachandran, director of the Center for Brain and Cognition at the University of California, San Diego, directed a study that showed that the angular gyrus is at least partially responsible for understanding metaphors. Right-handed Patients who had damage to their left angular gyrus and whose speaking and comprehending English was seemingly unaffected, could not grasp the dual nature of metaphor. Dr. Vilayanur Ramachandran on an episode of PBSs NOVA Television program. ... The University of California, San Diego (popularly known as UCSD, or sometimes UC San Diego) is a public, coeducational university located in La Jolla, California. ... Look up metaphor in Wiktionary, the free dictionary. ... A person who is right-handed is more dextrous with their right hand than with their left hand: they will write with their right hand, and probably also use this hand for tasks such as personal care, cooking, and so on. ...

Given a common metaphorical phrase, each patient could give only a literal meaning. If pressed, they could invent a wild interpretation but it was well off the mark.

In another exercise, the patients all failed to be able to describe a bulbous object as "booba" and a jagged object as "kiki," whereas more than 90% of unaffected subjects succeeded in the test. This showed an inability to connect visual stimuli to language.

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.

Out-of-body experiences

Recent experiments have demonstrated the possibility that stimulation of the angular gyrus is the cause of out-of-body experiences. [1] Stimulation of the angular gyrus in one experiment caused a woman to perceive a phantom existence behind her. Another such experiment gave the test subject the feeling of being on the ceiling. This is attributed to a discrepancy in the actual position of the body, and the mind's perceived location of the body. This phenomenon is similar to phantom limb syndrome.hannah is cool Phantom limb is a phantom sensation in amputated or missing limbs. ...
