the right supramarginal gyrus causes humans to project emotions on others, inhibiting the ability to be empathetic. In addition, this disruption also causes people to be more egocentric, mainly because they are not able to perceive the emotions of those around them. Both the left and right supramarginal gyri of healthy, right-handed individuals are shown to be active when making phonological word choices. Individuals who had lesions to the left hemisphere had more difficulty than those with lesions to the right hemisphere, reinforcing the dominance of the left hemisphere in language.

Although the supramarginal gyrus is not considered a major portion of the language circuit, it still works with the angular gyrus to attempt to link words with meanings. It is also bound caudally by the

The right-hemisphere supramarginal gyrus appears to play a central role in controlling empathy towards other people. When this structure is not working properly or when individuals have to make very quick judgements, empathy becomes severely limited. Research has shown that disrupting the neurons in
