Neurocognitive Performance During Space Flight. Validation of a Test Battery
Not Applicable
- Conditions
- Healthy Volunteers
- Interventions
- Other: determination of cortical activity
- Registration Number
- NCT02805400
- Lead Sponsor
- University Hospital, Caen
- Brief Summary
The main objective of this experiment is to evaluate the alterations in brain cortical activity induced by micro- and hypergravity conditions.
A secondary objective is to correlate changes in brain cortical activity and brain oxygenation level with neurocognitive performance.
Another secondary objective is to differentiate between the influences of hemodynamic and electro cortical changes and the influence of stress on cognitive performance alterations

Group Intervention Description Neurocognitive performance determination of cortical activity 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.
