当心脏跳动时，一个电子信号就会从心脏的顶部传到一个心腔（位于上部），然后是位于下部的心腔，当它收缩时，也是按照这样的顺序。
When the heart beats, an electrical signal passes from the top of the heart, near the atria (upper chambers), down through the ventricles (lower chambers), and the chambers contract in that order.
记住：当行情只是跌破每日的底部下面一美分或者上涨超过每日顶部上面一美分不是趋势改变的信号。
Remember that breaking one cent under a daily bottom or going one cent over a daily top does not change the trend.
另外，这些研究认为，通过“偏置”或者加强信号，“额-顶部网络”可在视区内引起信息处理能力的改善。
Those studies have additionally suggested that the frontal-parietal network may induce this improved processing in the visual areas by means of some "biasing" or enhancing signal.
