"Activity patterns of neural structures directing the orienting, executive and alerting attentional subsystems and process of entering into NREM sleep in the sleepiness and fatigue states - fMRI study."

About

The purpose of this study was to analyze the activity of neural networks involved in the orienting attention and executive control processes from the perspective of diurnal variability. The study results showed the occurrence of time-of-day–related variations in neural activity of brain regions linked to the orienting attentional system, simultaneously providing arguments for temporal stability of the executive system and default mode network.
