Abstract
Objective:
To examine further the role of the amygdala in the recognition of facial expression in adolescents.
Method:
Twelve healthy adolescents were studied using functional magnetic resonance imaging technology during a task of facial affect recognition and a visual control task.
Results:
All subjects demonstrated a significant increase in signal intensity in the amygdala for the facial expression recognition task.
Conclusions:
The data are consistent with previous work in healthy adult subjects implicating the amygdala as essential for the recognition of fearful facial expression.
