Here’s a thought: What IS a thought? I know it involves my brain, and my brain is made of neurons. And my brain’s neurons are listening to other neurons all over my body. But how do those neurons actually work? Maybe you’ve heard that it involves electricity, but does that mean you’ve got little zaps and lightning bolts running through your veins like Pikachu? Don’t worry, I’m here to set you straight on what a neuron is, what an action potential is, and how fast your nervous system really communicates.

As someone else said, the most impressive thing I learned in this video is that cockroaches can regrow their legs. Except that apparently adult cockroaches like this one do not. So the production crew seems to have told some lies. (Also, I learned that RU-vid apparently allows animal torture, which I thought was against the TOS.)

5:48 in case you're curious,here's what people thought before that: Three different theories of nerve function were debated as the seventeenth century drew to a close. First, many scientists still adhered to the notion of spirits running through the hollow nerves to contract the muscles or convey impressions to the brain. This was an ancient idea, but Rene Descartes, among others, embraced it. A second theory held that the nerves secrete droplets of fluid onto the muscles to activate them. Thomas Willis, for example, thought that when nerve fluids mixed with blood and fermented, they could cause minute "explosions," which would result in muscular contractions. The third theory was the idea that the nerves transmit information by vibration. This idea found its champion in Sir Isaac Newton, who attributed color perception to different waves of light causing corresponding vibration patterns in the nerves from the eye to the brain.

No, it's not that easy. A lot of things change around a Neuron that is fired frequently. For example, the amount of tunnel and pump proteins around the axon, the amount of synapses, or the amount of molecules released into the synapse per unit of current all may increase depending on the nerve cell at hand. Of course, quicker signal transfer through myelin increase helps, too, but it's not a one explanation fits all.

Those ion pumps are fueled by ATP which is generated using food calories, so no, this isn't a practical reusable energy source - you wouldn't burn a steak to power a car, would you?

Really, I appreciate you thinking my brain has any potential enough to power a lightbulb, but I think I need to stock up on the little provisions of energy I have. Thanks for the concern though!

Except it won't because the roach is fully mature and won't moult again. Also the ice water didn't sedate the roach. It agonised and paralysed the roach, but it didn't put it to sleep. It might have drowned the roach, though. Insects have book lungs and cannot hold their breaths like humans can (not that we can hold our breath while paralysed or asleep either.) I know crickets can die in mere seconds in water so shallow they can literally wade in it. So maybe the roach didn't feel the loss of its leg? Maybe it was already dead from drowning...

I hope you see this, Dr. Joe. This gives more information for a different purpose, and I wanted to share this with you. We love watching this science kind of stuff. This one has a different significance to me, though. It's interesting to watch all the way through and I recommend you do. It's done in a very easy to understand way (he's very good that way). But around 17:30 he talks about the myelin which is stuff that surrounds nerves. Apparently, it helps the information travel down a nerve faster. The reason it gave me an "Aha!" moment is that in MS, the immune system attacks the myelin and destroys it. Having this explained the way it is helps me realize that one of the things happening is that the "turbo boost" the myelin gives nerves is being destroyed in MS suffers, ... and thus, making the nerves communicate slower than they normally would. This is why I love these shows. They can be helpful in more ways than just some fun knowledge.
