The Control of the Cardiovascular and Central Nervous System.
Abstract
Cardiovascular studies indicated the importance of beat-to-beat regulation of heart rate via the aortic nerve, the importance of the pericardium in minimizing stresses, and following positive acceleration in unprotected subjects acute cardiopulmonary congestion may occur in the post-acceleration period. Thus, subtile changes in adaptive mechanisms are important defensive mechanisms against the stresses employed. Other studies indicate that with a high +G force there is inhibition of ethanol sleep time response but with a low +G force augmentation of sleep time is produced. These may lead to important clues as to the nature of chemical changes and the effects of drugs taking place during acceleration. Studies on the effects of immobilization on muscle function indicate there is increased lysosomal activity which may account for the abnormal contractile function and may lead to important implications in prevention of muscle atrophy during immobilization.
