Mental fatigue and impaired response processes: event-related brain potentials in a Go/NoGo task.

22 Dec 2008 The effects of mental fatigue on the availability of cognitive resources and associated response-related processes were examined using event-related brain potentials. Subjects performed a Go/NoGo task for 60 min. Reaction time, number of errors, and ... Read more...

Mental fatigue: costs and benefits.

7 Jul 2008 A framework for mental fatigue is proposed, that involves an integrated evaluation of both expected rewards and energetical costs associated with continued performance. Adequate evaluation of predicted rewards and potential risks of actions is ... Read more...

Mental fatigue alters the pattern and increases the volume of cerebral activation required for a motor task in multiple sclerosis patients with fatigue.

30 Mar 2008 Fatigue is one of the most disabling symptoms in multiple sclerosis (MS) and there is increasing evidence it has a central origin. Our aim was to assess the impact of mental fatigue on motor task-related cerebral activation. Ten relapsing-remitting ... Read more...
