Abstract

The relations of the grasp-reflex strengths from right (R) and left (L) hands to human growth hormone (hGH) levels were studied in human neonates within the first day after birth. In right-handed (RH) males without familial sinistrality (-FS), grasp reflex from right and left hands directly correlated with hGH. In RH, -FS females, grasp reflex from right and left hands inversely correlated with hGH. In -FS, LH males, grasp reflex from right and left inversely correlated with hGH (no significant correlations in LH, -FS females). The R-L grasp reflex decreased linearly with hGH, only in RH, -FS males. These results indicated that hGH may affect cerebral development according to genetically predetermined neural patterns in utero.

摘要

在出生后第一天内，对人类新生儿右手（R）和左手（L）抓握反射强度与人类生长激素（hGH）水平之间的关系进行了研究。在没有家族性左利手（-FS）的右利手（RH）男性中，右手和左手的抓握反射与hGH直接相关。在RH、-FS女性中，右手和左手的抓握反射与hGH呈负相关。在-FS、左利手（LH）男性中，右手和左手的抓握反射与hGH呈负相关（在LH、-FS女性中无显著相关性）。仅在RH、-FS男性中，R-L抓握反射随hGH呈线性下降。这些结果表明，hGH可能根据子宫内基因预先确定的神经模式影响大脑发育。
