This study explores the neural mechanisms of gesture comprehension and production in people with aphasia (PWA) and healthy controls, focusing on brain synchronization during gesture observation and reproduction. Using EEG hyperscanning, neural coupling between the encoder (PWA) and decoder (healthy participant) was analyzed during tasks involving social, affective, and informative gestures with both positive and negative emotional valence.
