记忆状态下脑波超慢涨落图分析

The Analysis of Supra-Slow Fluctuation of Brain Waves in Memory State

用本实验室新建立的脑波涨落图技术(ET)研究记忆状态下的大脑超慢(S)活动,获得一系列新的结果。良好的记忆效率,需要良好的全脑活动背景和左右脑关系。大脑左半球表现明显的功能优势,包括谐振优势,S_2优势和S_3/S_4系优势;F_7区和P_3区为左脑优势脑区。右脑和额脑则具有储备作用。记忆状态中发现了一系列优势超慢频率,包括S_2、S_3与S_(136)等。对这些频率系统可能的神经生理和神经化学机制进行了分析。提出人脑记忆功能的系统理论。所得结果可用于航天员脑功能选拔、空间脑功能试验、和各类正常的和异常的脑功能研究。

The “encephalofluctuograph technology(ET)” newly established in our la-boratory was applied to the study of brain supra-slow activity in a memo-ry state and a series of new results have been obtained.Good memory per-formance requires optimal background of the whole brain activity and theleft-right brain interaction.The left hemisphere of the brain demonstratedobvious functional predominance,including dominant harmony, S_2 and S_3/S_4system dominance,and dominant F_7,P_3 activity in the left brain.Meanwhile,the right brain and frontal brain worked as backup resources.A series ofdominant supra-slow frequencies have been discovered in a memory state,such as S_2,S_3,S_(136),etc.The possible neurophysiological and neurochecmicalmechanisms of these frequencies were analysed.A system theory of memoryfunction of the human brain was suggested.The obtained results wereapplicable in brain function selection of astronauts,brain function experi-ments in space,as well as different kinds of studies on normal and abnor-mal brain functions.
