The Influence of Transcranial Micro-electric Current Physiological Training on Cerebral Function Under Altitude Hypoxia

摘要: Objective To investigate the effects of transcranial micro-electric current physiological training (TMCPT) on cerebral function (CF) in order to provide technology and methods for maintaining CF under altitude hypoxia. Methods Forty healthy volunteers served as subjects, who took flight were trained by TMCPT condition hypoxia (3,700 m above sea level). Current intensity was limited within safe range. Subjects twice per day (one morning other afternoon), each 5 min. Neurobehavioral ability index separately observed rush entry phase (first 10 days after entry) various resident phases (resided 1, 2, 3 months). Self-evaluating questionnaire Pittsburgh Sleep Quality Index used evaluate sleep quality different phases. Results ① In phase: digital scan, memory simple visual reaction time, complex pursuit aiming consecutive performance significantly increased at (t = 1.982–4.412, P < 0.05) compared with those 1 day. ② Resident neurobehavioral month, only scan time months 3.744–5.812, month. ③ evaluation: indexes had a significant reduction 1.833–3.552, 0.05). Conclusions can improve The β-frequency brain-wave feedback be promote CF, α-frequency utilized quality.
