Phillip Cuculich, a cardiac electrophysiologist at Washington University in Saint Louis.

华盛顿大圣路易斯分校的心脏电家菲利普·库库里奇说到。

Because up until the 1990s, the tools were limited, electrophysiology, you know, behavior.

因为在20世纪90年代之前，工具很有限，电，你知道的，行为。

Scientists use a variety of tools and techniques to study the nervous system, which include brain imaging, electrophysiology, genetics and behavioural testing.

科家使用多种工具和技术来研究神经系统，包括脑成像、电、和行为测试。

Everything from the direction of electrical flow through the nervous system, all from looking at tissue that was not alive, no electrophysiology, no behavioral experiments, just raw, but incredible, supernatural seemingly.

从神经系统中电流的流向，所有这些都只是通过观察未活组织得出的，没有电实验， 也没有行为实验，但数据却是原始的、令人难以置信的， 仿佛超自然一般。
