Abstract
Broca's area, which comprises the inferior frontal gyrus and its surrounding regions, is associated with language function, Recet functional imaging studies showed that it is also related to processing nonverbal communication. We study aimed to determine the types of action disorders that occur after damage to Broca's area.
Here, we report four patients with left inferior frontal lesions that included Broca's area. All patients exhibited impaired gestures in response to verval commands, while the performances regarding imitation and actual tool use were better.
These results indicate that Broca's area mediates action production and that a lesion in this area can case ideomotor apraxia. We conclude that Broca's area imay be not only associated with language function but also with nonverbal, such as social cognition.
