简要总结
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.
详细描述
Gestures are essential in non-verbal communication, complementing speech by expressing emotions, intentions, and cognitive states. This study examines 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, we analyzed neural coupling between the encoder (PWA) and decoder (healthy participant) during tasks involving social, affective, and informative gestures with both positive and negative emotional valence. Methods: Seven dyads of participants participated in this study. The research was approved by the Ethical Committee of the IRCCS San CamilloHospital
