The findings shed light on how stress leads to mood disorders, and how changes in sleep contribute to this.
Apoptosis plays a critical role in brain development as it influences the thickness of layers in the cerebral cortex, variety, and layer cell density. Alterations in how cells perform division and apoptosis lead to the development of abnormal cortical structures as seen in a variety of neurodevelopmental disorders, including autism.
