对14名青年进行了普通的CNV实验和无运动CNV实验。发现了一种与心理负荷解脱伴随出现的脑电波——解脱波EML。EML波不同于普通CNV后形成的Ⅴ波,不含诱发电位外源性成分和运动成分,代表心理负荷的解脱,纯属一种只与心理活动相关的脑电波。目前尚无理由将EML波视为LPC(LatePositive ComPlex)的一员。提出CNV心理因素的性质,可能是在完成同种任务时由期待、意动、动机、朝向和觉醒等多种心理因素综合构成的心理负荷加重。本工作采取了离线式排除伪迹程序,在数据处理上做出了总平均图(Grand Average Records)。
【英文摘要】
The Usual CNV and Non-motor CNV were investigated on fourteenyoung men. A wave (EML) which followed the extrication of mentalload was discovered. The EML which is different from wave V formedafter Usual CNV, does not contain any exogenous components of EP ormotor components and is just a pure mental brain wave elicited bypsychological factors. At the present stage, it is too early to considerEML as a component of LPC. The Psychological factors in CNV havebeen inferred because of the increase of mental load ...
