Language Alterations due to Right Hemisphere Lesions

Leticia Lessa Mansur

Abstract

<p>The role of right hemisphere (RH) in language and communication has been a subject of debate over the last decades. Studies derived from RH lesions and functional neuroimaging in the past years have, nevertheless, shed some light on the multiple roles of the RH in linguistic processing and several aspects of communication in a broader sense. It is now recognized that the RH plays an important role in decoding “non-literal” language, such as emotional prosody, metaphors and figurative language interpretation.
