Neurocognitive Performance During Space Flight. Validation of a Test Battery

"Cortical activity will be determined under changing gravity level by electroencephalography (EEG/LORETA). Brain hemodynamics change will be evaluated by NIRS. Heart rate and respiratory evaluation will be indicators of cardio-vascular and central nervous arousal and stress. Cognitive performance will be evaluated by computerized tests.~For these methods only commercially available CE marked devices will be used."
