 I'm super excited about this. I will try not to waffle on too much. This really tripped up the people who were trying to characterize the nervous impulse back in the 19th century. Because every time they would cut a frog to try to measure its nerve signal, they would get this current that was interfering. And they were just like, oh, don't know what this is, going to ignore it. It's only like 150 years later, we start to understand what the deal is. So the deal is this.
