A REPORT OF GROUND EXPERIMENTS FOR BRAIN FUNCTION IN SPACE
-
摘要: The brain function is of crucial importance in space adaptation and astronaut performance. According to the theory of nonequiliblium fluctuations a new technology, ET (Elec-troencephalofluctuography [EEFG] Technology), has been developed in our laboratory for space application. Information of different attracters, especially the dominant supra-slow (S) oscillations of the brain can be abstracted from the fluctuating brain waves. Specific Sspectral lines related to neurophysiological and neuro-chemical activities have been identified and charcteristic spatial patterns have been figured out. ETanalysis has been carried out in a series of ground experiments: (1) 20 degrees head lowered suspension experiments in rabbits; (2) 2Gz hypergravity experiments in rabbits; (3) effects of antimotionsickness drugs on rabbits during suspension; (4) clincal observations on patients with brain circulation diseases. Valuable information has been collected in all these experiments, which can hardly be obtained by means of other existing techniques. The potentiality of ETapplication in space research was discussed.
