Monitoring Autonomic and Central Nervous System Activity by Permutation Entropy during Short Sojourn in Antarctica
The aim of this study was to monitor acute response patterns of autonomic and central nervous system activity during an encounter with Antarctica by synchronously recording heart rate variability (HRV) and electroencephalography (EEG). On three different time-points during the two-week sea journey,...
