The right hemisphere of the brain dominates self recognition
The right hemisphere of the brain dominates self recognition, emotional familiarity and ego boundaries. After injury, the left hemisphere tends to have a creative narrator leading to excessive, false explanations. The resistance of delusions to change despite clear evidence that they are wrong likely reflects frontal dysfunction of the brain, which impairs the ability to monitor self and to recognize and correct inaccurate memories and familiarity assessments. Thus, right hemisphere lesions may cause delusions by disrupting the relation between and the monitoring of psychic, emotional and physical self to people, places, and even body parts. This explains why content specific delusions involve people places or things of personal significance and distort ones relation to oneself, the author explains.
