Abstract

From 4 or 5 postnatal days, rat pups were either reared by their mothers (MR) or artificially reared (AR) without their mothers by infusion of 'milk' through a gastric cannula. In AR, but not MR, pups the left eye was more likely to open first than the right eye (P less than 0.001). The left-biassed eye-opening of AR pups may be a manifestation of stress-induced lateralisation of their brains.

摘要

从出生后4或5天起，将新生大鼠幼崽分为两组，一组由母鼠抚养（MR），另一组则通过胃插管注入“乳汁”进行人工抚养（AR），使其在无母鼠环境下成长。在人工抚养组（AR）而非母鼠抚养组（MR）中，幼崽的左眼比右眼更有可能先睁开（P < 0.001）。人工抚养组（AR）幼崽的左眼偏向性睁眼现象可能是应激诱导的大脑偏侧化的一种表现。
