Funny, I thought that this video was pretty useless for me.

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 KZbin 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.

An even more interesting question is what is cause of the very first neuron creating the electric signals. Sure, of course the chain-reaction for sensations begins from physical interactions of the outside world like pressure or temperature. But I'm asking about the chain-reactions that come the other way down the pipeline so to speak; thoughts and decisions. My best guess is quantum uncertainty starts the chain reaction in the cells, and we only perceive those as being of our own volition. I mean, think about it. What else could cause the threshold of that first neuron to be surpassed in a given scenario of a thought or decision to perform an action? If not physics outside of our control, what else could be causing this first neuron to fire in a given thought or action? This thought experiment suggests to me that we either: 1- have no free-will; physics outside our control cause chain reactions of neurons firing out a thought or action. Similarly to how a sensation works and is perceived 2- or that if free will does exist that that suggests that we have some kind of control over the first neuron in the chain-reaction even without a cause that can be described by physics or randomness in quantum fields In other words, I believe it's rational to assert that we either have no free will or something that cannot be defined by physics or quantum mechanics (yet, or ever) has control over the physical world and is unique to each consciousness; a "soul" of sorts.

Not quite. It's the same topic (animal electricity). Not only that, he tells you all you need to know to answer the question yourself. Animal electricity is the same as electricity used for appliances (it's all just electricity), demonstrated when he used the wires to stimulate the cockroach leg, and when touching the leg created its own electrical signal like those of the electronic devices in the room. Given that it's all the same electricity, you can power a device with "animal electricity". An action potential is 110 mv (40 mV + 70 mV), so you only need about 1090 neurons to be firing simultaneously to power a 120 V lightbulb (120 V / 0.11 V). Not a tall order for the 86000000000 neurons in your brain. As for hooking it up... well, that's the hard part

[@manaylodha]

@@VoxTenebrae don’t go with just voltage remember that amps is almost as important, one neuron only produces about 10^-12 amps so I don’t think they are enough, you do the maths do hehe

[@cahidijoyoraharjo7833]

Thank God I read this comment before wasting 20 minutes of my life.

[@VoxTenebrae]

@@manaylodha That's a good point, I hadn't considered amps. The lowest amp usage for a lightbulb I could find with a quick search is 0.36 amps for a 40 W lightbulb. So you'd need 360 billion neurons (0.36 A / 10^-12 A/neuron). In that case the answer would be no. A single human brain couldn't power a lightbulb, but if you had at least 5...

[@stupidbaby2858]

Recognizing and being impressed that the nervous system conducts and operates with electricity should be the starting point to develop intelligence in more people . Not just scientific intelligence (there's plenty of that) but social, personal intelligence, which is not only virtually non-existent, but crosses past zero into the negative measurements, i.e., stupidity. An idea is a thought, but a thought only exists as an action, that is to say, it exists as a flow or pattern of electricity, and yet people treat ideas as property, as if thoughts are things one owns and must defend. Once anyone voices an idea, not only does that very act of communication is giving it away to others, but the reception of that thought is immediately met with the entire nexus plexus of another's mind and therefore is modified through interpretation. And yet people hold onto their ideas as if ideas are fixed, permanent, and have validity by resisting temporal change.

Myelin is actually what determines our skill in any given thing. The more you use that neuron chain, the more myelin it grows. This myelin speeds up the neuron chain, like you mentioned, and the more myelin we have, the better we are at that skill. Give the Talent Code a read, it talks a lot about that sort of stuff.

[@son5051]

Is it true for all kinds of memories?

[@infiniti2011]

@@son5051 Yep, most skills can be improved with more myelin. Albert Einstein's brain was actually shown to have a higher concentration of myelin all around, than most people, which is probably why he was so smart.

[@thesavantart8480]

[@infiniti2011]

​@@thesavantart8480 Yeah, that's absolutely true. But that was more for everyday practical knowledge. For physics, mathematics, and data, absolutely not. People on the spectrum may have terrible memory in some places, yet unlimited recall in others. Einstein was believed to have Aspergers and ADHD, so that might be the cause of those issues.

[@lelrond]

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.

[@sarahcameron320]

Jo and the it's ok to be smart team, thank you as always for such great content! As a physical therapist working with a lot of patients in pain, I would just like to point out/correct a statement that you made about pain...we don't have "pain nerves" or "pain sensors" etc. The correct terminology is nociceptors and nociception. It may seem like a small semantical thing, but pain is a construct of the brain and nociception is only one part of the picture of the pain experience, and that makes using the correct terminology so important!

I developed epileptic convulsions as a child and from now on I take pills daily. Even though I am an ancient old man I’ve led a long seizure free life. No more epilepsy. I have one problem though. I don’t quite understand what causes convulsions. Is it the axons or the synapses that are malfunctioning? How does that medication keep the impulses under control? What prevents the impulses it from flying around to other neurons?

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...

@DrJoeHanson I think it was unnecessary to mutilate an living organism just to demonstrate galvanism. Also, I did not find it "cool" seeing a severed body part twitching at the beat of a song. As a scientist and educator, I invite teachers and researchers to consider the ethical implications of their actions and to demonstrate the young generations the respect and compassion that every living organism deserves. Joe, putting an animal through unnecessary pain, and doing so without any hesitation or regret as you did in this video, is not a good example of what ethical scientific research should be.

In a similar way that multiple neurons can understand how single neurons work, AI is able to simulate how single transistors work. Often, when people say that AI will never be more intelligent than humans, they fail to recognize how many smaller things that on their own lack intelligence can add up to create something vastly more intelligent. Also, there's the fact that two people have more intelligence combined than one person, so it stands to reason that hundreds of humans working on AI could easily develop an AI with intelligence greater than one human.
