关于CNV是复合波的直接证明

DIRECT PROOF OF CNV AS A COMPOSITE WAVE

本工作以青年为被试者,包括三项实验:普通CNV,无运动CNV和半机率CNV。观察到:(1)修通CNV的晚成分和全波大于无运动CNV,其全波相减所得之差波即为CNV中的纯心源性意动成分,它应该认为是以复合波形式存在于CNV中的运动预备电位。(2)半机率CNV的早成分和全波大于普通CNV。(3)半机率CNV的早成分、晚成分和全波皆大于无运动CNV。这些结果证明,CNV中包含着运动预备电位,从而为CNV是复合波的新概念提供了新的直接的证据。

Three items of CNV were performed on fourteen subjects aged 19-22.The items are as follows: Usual CNV (U.CNV) , Nonmotor CNV (Nm.CNV) and Half-probability CNV (Hp. CNV). It is observed that. (1)The late section and full CNV of U.CNV amplitude are larger than Nm.CNV, the difference of the late section is the largest, and the differencewave between U.CNV and Nm. CNV is the component of conation thatisa pure psycho-genous wave and is the Readiness Potential of Kornhuber etal. in CNV; (2)The early section and full CNV of Hp. CNV amplitudeare larger than U. CNV; (3)The early section, late section and full CNVamplitude of Hp, CNV are larger than Nm. CNV. These results sugg-est that the conation is a psychological factor in CNV; the Readiness Po-tential is a component of CNV. This experimental result is a new directevidence of the latest view that CNV is a composite wave.
