反应时是中枢神经系统机能状态的客观指标之一。测定和分析反应时是进行心理学、生理学、老年医学、运动医学及临床神经、精神疾患研究的手段之一。然而,过去由于缺乏适用的反应时测定装置,限制了它的应用。为了研究人在高山低氧环境中中枢神经系统机能状态的改变,本室研制了半导体反应时测定器,在此基础上,我们又研制了集成电路反应时测定器。该仪器能测单纯光反应时和选择光反应时,既可以用人工 Response is one of the objective indicators of central nervous system functional status. Determination and analysis of the reaction is one of the means of psychology, physiology, geriatrics, sports medicine and clinical neurological and psychiatric disorders. However, its application has been limited in the past due to the lack of a suitable reaction time measurement device. In order to study the change of functional status of central nervous system in alpine hypoxic environment, we developed a semiconductor reaction time tester. On this basis, we also developed an integrated circuit reaction time tester. The instrument can measure a simple light reaction and the choice of light reaction, either artificial
