Using an optical method for measuring membrane potential, we monitored spontaneous action potential activity in the embryonic chick heart at the very early developmental stages, and found that spontaneous electrical activity was present at the developmental stage of 8 somites before the initiation of the heartbeat.
我们使用光学方法测量膜电位，监测了胚胎期雏鸡心脏在非常早期发育阶段的自发动作电位活动，发现自发电活动在心跳开始前的8体节发育阶段就已存在。
