The Influence of Antarctic Environment on Sleep in Man : Part 2. Autonomic Functions and States of Sleep (Biology and Medical Science)
Five healthy male subjects, members of the Japanese wintering party, participated in the investigation of seasonal changes in autonomic functions during sleep, besides relationship between autonomic functions and states of sleep at Syowa Station, Antarctica. Sleep polygraphic recordings including th...
