Generation of activity-rest patterns by dual circadian pacemaker systems: a model.

abstract：:Cognitive performance is impaired by fatigue arising from sustained wakefulness and alcohol. Three recent papers directly compared the effects of increasing fatigue and blood alcohol concentration (%BAC) to provide a framework for understanding fatigue-related cognitive impairment. While the expression of fatigue-rela...
