The Effect Sleep and Bully on the Structure of the Dorsomedial Prefrontal Cortex

This study assessed the structures of the dorsomedial prefrontal cortex (dmPFC) in relation to sleep and bully, using neuroimaging. Sleep problem is associated with reduced dmPFC thickness in general and reduced dmPFC volume in only bullies. These may suggest the importance of sleep in dmPFC’s emotional functioning, such as bully.
