  Good question! Because neurons differ widely in location and function throughout your body, there are a number of possible outcomes depending on what exactly you mean by “all”. I’ve listed a few of those outcomes below!

  Every neuron in your entire body: you die.

  Every neuron in your body under conscious control: you die.

  Every neuron in your Central Nervous System(brain and spinal cord): you die.

  Every neuron in your brain: you die.

  Every neuron in your brain that’s not in your hindbrain: you still die, but slightly slower and more agonizing.

  Every neuron in your cerebrum: you die, but going from seconds to minutes here is progress!

  Every neuron in your forebrain: you might conceivably survive this, albeit with severe personality changes and massive cognitive declines. Then again, it’s almost certainly going to trigger a massive seizure. In which case you just die.

    Wow. So many different outcomes. :D

    TLDR: You die.

  I guess it could cause a severe seizure or even catastrophic neural failure. The synchronous firing would disrupt the balance of excitatory and inhibitory signals in the brain, potentially damaging neurons and leading to a loss of normal brain function.

  The result might include a loss of consciousness, significant cognitive impairments, or even death, depending on the extent and duration of the event.

  But then again, I have no idea, since I ain’t an expert in that field and in fact am actually just a dog who figured out how to use a computer 🙃

  I’m not a neuroscientist or anything but I’d imagine you’d have a massive seizure and just die.

  Not sure it would be possible but got me thinking. The brain consists of around 100 billion neurons with a charge of around 0.07 volts at rest. That is a theoretical 7 billion volts. I am not a doctor or electrician but that would have to go somewhere, presumably earth. No idea of the consequences somewhere between none and spontaneous combustion would be my guess!!

    It does not need to go to earth. Take a 1.5v alkaline battery, connect one end of the battery to the other end – a large amount of current flows, no earth involved. The electric charge that a neuron can produce is basically like tiny cells of a biochemical battery. The problem is unlike a useful battery, the voltage difference between all the individual cells is not (and realistically cannot be) carefully organized in a series or parallel path from positive to negative, instead all the positive and negative connections are jumbled together into a complex network, meaning there’s no way of getting billions of volts out of it. It’s just not wired that way.

    Theoretically if you carefully constructed a series of hundreds of billions of neurons connected end-to-end-to-end in the right pattern you might end up with billions of volts (although end-to-end it would probably be the size of the solar system, so the billions of volts potential wouldn’t seem so impressive anymore on an astronomical scale) and you probably can’t pack it your neural-battery into a small space without the neuron’s insulator (myelin sheath) from breaking down and shorting out that voltage. Also it wouldn’t really be a brain anymore at that point. The complex maze of connections are what makes the thinking happen. If you make them all single-connected you’ve basically just got a really big, low capacity and relatively inefficient battery compared to better chemistries.

    Flowing all that current at once will certainly create a lot of heat though, you’re right about that. That heat is normally heatsinked by the intracranial fluids and conducted away by the relatively rapid bloodflow through around the brain to be dissipated in the skin and lungs. The brain is basically liquid-cooled and it’s a very efficient and tightly regulated system that rarely has issues. Such a high neutral output would probably overwhelm even the relatively robust cooling that bloodflow provides, though, leading to a condition called brain hyperthermia, which is part of the reason drugs like methamphetamine can be dangerous or fatal, as it can result in cell death, and in this case, probably brain death and overall death.

      This is the best answer and why I was thinking it wouldn’t be possible but couldn’t come up with a good explanation.
      Alsi Cunninghams law in action… post a dumb answer and someone will give the right answer. Thanks.

    I’m not an electrician either, but can all those volts be just added up?

  You get an aneurysm?

  • C4d@lemmy.world ⁨10⁩ ⁨months⁩ ago

    Aneurysms are not related to neurones. They’re bulges in the walls of blood vessels related to structural weakness. They can affect vessels that supply the brain and if they burst it can be catastrophic and rapidly fatal - is this what you were thinking of?

      Thanks for clarifying. I was merely guessing and making a joke.
