用振动探针探测了鸡胚上方的电场。这些磁场表明，出口密度约为每平方厘米100微安的稳定电流离开整个条纹，并通过外胚层返回其他地方。这些强出口电流的震中位于亨森节点附近。它们可能被外胚层泵入胚胎内空间，然后从条纹中泄漏出来，因为这是一个连接中断的区域。
The electrical fields above chick embryos were explored with a vibrating probe. These fields indicate that steady currents with exit densities of the order of 100 microamperes per square centimeter leave the whole streak and return elsewhere through the epiblast. The epicenter of these strong exit currents lies near Hensen's node. They are probably pumped into the intraembryonic space by the epiblast and then leak out of the streak because it is a zone of junctional disruption.
