基于大脑机制的亲子教养（翻译二十五）

Since the bottom-up stream is the one that is tied to our limbic system, it is the circuit that is vital to our immediate survival, the system that performs the neuroceptive, unconscious “first-take” screening of the information coming from our external and internal senses.

因为自下向上的流与我们的边缘系统相连的，所以它是对我们的生存至关重要的回路，这个系统能对来自我们外部和内在感觉的信息进行“先取”筛选。

This is the system that we use to appraise everything in life first for its immediate survival value and for rapidly assessing whether we are safe or in danger.

这个系统用来评估生存价值，以及快速评估我们是安全的还是危险的。

The amygdala is part of the lower stream, whereas the hippocampus functions, in part, as a bridge between the two streams.

杏仁核是下游的一部分，而海马体则是两条溪流之间的桥梁。

The amygdala receives from and feeds back to every sensory region of the brain, whereas the hippocampus receives information that has already been highly processed in a multi-sensory fashion by other regions of the brain and then shares this well-processed information with higher brain regions (LeDoux, 2002).

杏仁核接收并反馈到大脑的每一个感觉区域，而海马体接收的信息已经被大脑的其他区域以多感官的方式进行了高度的处理，然后与大脑更高的区域共享这些经过处理的信息。
