3、ythm.母亲和孩子之间的关联是很深厚的,新的研究提出了一种身体上的联系,这种联系比任何人所认为的都还要更深厚一些。母亲和孩子之间心理和身体上的亲密关系从怀孕的时候就开始了,那时母亲对发育中的胎儿来说意味着一切:提供温暖和营养,母亲固定频率的心跳对胎儿来说是一种抚慰。Thephysicalconnectionbetweenmotherandfetusisprovidedbytheplacenta,anorgan,builtofcellsfromboththemotherandfetus,whichservesasa

8、stingtheymayberelatedtothehealthofthebrain.对细胞来说从一个个体进入到另外一个完全不同的个体中并结合在一起是很常见的,这一点太了不起了。我们习惯认为自己是独一无二的个体,这些外来的细胞好像与这个观点不符,而且表明了大部分人都携带着其他人的遗留痕迹。这一点或许很值得注意,一项新研究的结果则更让人大吃一惊,研究结果表明来
