为了找到答案,他和他的同事在不同硬度的基质上培育胚胎心脏细胞。
To find out, he and his colleagues grew embryonic heart cells on matrixes of differing stiffness.
Now, in the heart action potential is moving from one heart muscle cell to another over the surface of the heart.
心脏中的动作电位,沿相邻心肌细胞在心脏表面传递
When we measure EKG's, what we're measuring is the activity of all these cells within our heart performing action potentials.
当我们做心电图的时候,我们所测量的是心脏内能发出,动作电位的细胞的活动状态
In the heart it turns out that the cells of the heart are electrically coupled together, so if an action potential moves down this cell it directly moves into the next cell.
在心脏中,事实证明,心脏细胞是电偶联的,所以如果动作电位在一个细胞中传递,那么直接就能传递给下个细胞
