Role of left lateral prefrontal cortex in positive emotion regulation: Insights from dyslexia.

ABSTRACT: Emotion regulation emerges during childhood and engages prefrontal brain systems. While most developmental studies focus on the neural underpinnings of negative emotion regulation, less is known about the neuroanatomical correlates of positive emotion regulation. In adults, prefrontal areas in the left hemisphere are critical for positive emotion regulation, but whether this association is present in children is unknown. We investigated whether smaller gray matter volume in left prefrontal regions related to worse positive emotion regulation in children with and without dyslexia. Because dyslexia is a neurodevelopmental disorder of reading in which there may be greater variability in left prefrontal structures, it offers a unique window into the neural basis of positive emotion regulation.
