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

Peter Mukli, Andriy Yabluchanskiy, Tamas Csipo

Sleep deprivation (SD) is associated with decreased cognitive performance, but the underlying mechanisms are poorly understood. To assess the impact of SD on cerebral hemodynamics in the frontal lobe, functional near-infrared spectroscopy (fNIRS) me…

Mental workload during n-back task captured by TransCranial Doppler (TCD) sonography and functional Near-Infrared Spectroscopy (fNIRS) monitoring

Peter Mukli, Andriy Yabluchanskiy, Tamas Csipo

The authors used this dataset to assess the neurovascular coupling responses evoked by a cognitive paradigm with the aid of TransCranial Doppler (TCD) sonography and functional Near-InfraRed Spectroscopy (fNIRS). Fourteen healthy young individuals w…

Body Sway When Standing and Listening to Music Modified to Reinforce Virtual Reality Environment Motion

Jefferson Streepey, Shaquitta Dent

The increased likelihood of falls as a consequence of aging or disease is generally associated with rising levels of body sway during stance.  The use of virtual reality (VR) for studying the role in vision in regulating body sway is well establishe…

In-hospital physical activity measured with a new Bosch accelerometer sensor system

Severin Schricker, Nico Schmid, Moritz Schanz, et al.

Extended hospital stays and readmissions are associated with high costs and burden of disease. Effective ways to predict patient outcomes, select those at risk of adverse outcomes, and to prevent these accordingly, are lacking. Physical activity mea…
