Associations among white matter microstructural changes and the development of emotional reactivity and regulation in infancy.

Molecular psychiatry Apr 23, 2025
Deficits in emotional reactivity and regulation assessed in infancy, including high levels of negative emotionality (NE), low positive emotionality (PE) and low soothability, can predict future affective and behavioral disorders. White matter (WM) tr...
