Aims:
A NRA to evaluate the aspects of ICE environments absent in current literature.  Specifically, the impact of long duration stays on cognition. This task informs Sensorimotor gap SM26.

 

Aim 1: Perform structural and functional neuroimaging prior to, immediately after, and 6 months after the winter-over. This includes the administration of cognitive tests inside and outside of the scanner.

 

Aim 2: Assess cognitive performance on a wide range of cognitive domains with the Cognition test battery during the period of confinement and isolation on a monthly basis.


Aim 3: Investigate changes in sleep duration, sleep-wake rhythms and light exposure with continuously worn wrist actigraphy during the period of confinement and isolation.

 

Aim 4: Investigate physiologic changes in heart rate, heart rate variability, and sleep structure with monthly 24-h ECG measurements during the period of confinement and isolation.

 

Aim 5: Investigate changes in psychomotor vigilance performance, mood, depressive symptoms, and subjective assessments of workload, stress, sleep quality, tiredness, sickness, and conflicts among crewmembers during the period of confinement and isolation on a weekly basis.

 

Aim 6: Unobtrusively and continuously monitor crew cohesion and team structure with proximity sensors built into the wrist-worn actigraphs during the period of confinement and isolation.

 This task is on the BMed Critical Path
