Effect of 24-hour sleep deprivation on cerebral hemodynamics and cognitive performance

Peter Mukli, Andriy Yabluchanskiy, Tamas Csipo

We assessed the impact of 24-hour sleep deprivation on the global properties of frontal lobe functional networks and on cognitive performance. fNIRS measurements were carried out in the resting state and in response to a finger-tapping paradigm.
