    We all sort of/kind of knew this but we never realized this? That’s kinda crazy. Glad it has been formally established.

    The parts for dummies like me:

    Forebrain and midbrain: the thing you think of when someone says brain

    Hindbrain: the brainstem/bottom part going to spine

    Neat, has nothing to do with your two hemispheres if you haven’t read the article.

    Amazing what one can learn in the details. TIL that face musculature is controlled by the hindbrain. I always thought they were run like all the other actively controlled muscles.

      One brain gnawing on a bone and jerking off, the other reciting poetry and wondering if the stocks laid in for winter are sufficient

    It’s not too dissimilar to Windows OS. If you’ve gone into the System application of the Control Panel, you can flip the Windows host to optimize for services or applications. And I think they mean the hindbrain, as in the brain stem and medulla oblongata, is one type of neuron, whereas the lobes — occipital, temporal, frontal, etc. — are another type. The former is likely genetically-optimized for fight or flight, reflexes, and such, whereas the latter is for added analysis, deeper reasoning, etc.

    Did I read that right? Maybe I muddied some brain structures between these types of neurons? Eh, I’m no neurologist.

    In a college course, we discussed the idea of System 1 and System 2. The System 1 (autonomic, unconscious) handles primitive work — fight or flight, organ management, and feelings, but it’s reliable, whereas System 2 requires more conscious effort and it’s linked with consciousness and it can intercede in a decision, if applied. So, now, there is genetic evidence to support this System 1&2 idea. Fascinating.

    NOTE: I said Windows had a similar setting; however, unlike us meat suits, we shouldn’t and can’t swap between these.

      Hindbrain and the lobes aren’t neuron. Neither are they a type of neuron.
      They have neurons. Of different types.

    Wow, that was a really fascinating article. I suppose this will also factor in to understanding the differing ability for higher thought between us and other animals.

      It’s not unique to humans at all. They originally found the two types of brain cells by looking at mouse embryos. Then,

      "Finally, the researchers looked back over 550 million years of evolutionary time. They found the same two-origin brain pattern in chickens; zebrafish; and, remarkably, in acorn worms, tiny creatures living on the ocean floor that share a distant common ancestor with humans. Jellyfish, which diverged from humans about 600 to 700 million years ago, have two nervous systems at different ends of their body.

      “Our research suggests that evolution took two existing neural systems and pushed them together spatially,” Loh said. “Having the brain as one organ would probably be more efficient, but we rely on this primordial way to make the brain as two separate pieces.”

      We’ve long known the forebrain, midbrain and hindbrain control different things, we just didn’t know the hindbrain neuron cells evolved so fundamentally differently. Being able to grow the right kind in a lab will enable research that wasn’t possible before.
