Many cases of humans that are by all appearances normal but missing massive volume of brain parenchyma like the middle figure here.pic.twitter.com/u8zt9G2tDg

Do this mean you saw someone who had it, or that you just saw the presentation of this case?

that’s amazing, still. is most of what we need to live on the outer layer of the cortex or something?

You find the critical/essential areas deeper in the brain. They also are the most "ancient" (evolutionarily) and most conserved (you find similar areas in many other species). Speaking very generally, the thinking is- If the change happens over time our brain adapts. ...

... So, if brain tissue is pushed or compressed slowly over time (hydrocephalus or a tumor, for example) then our brain is plastic enough to compensate, at least to a degree. And there are some extreme examples of this.

what’s weird to me is that we need the brainstem, we need the limbic system, but (almost?) all the tissue here is on the outer layers... amazing if it really can just progress slowly like this and you can end up with a functional human with just a big gap... really astonishing

We have a very crude notion of what is normal and normal functioning. The functioning part is in the outermost layer called cortex. But even now we have seen cells can communicate without being chemically/physically connected, with electromagnetic waves. =D brain is amazing!

I'm pretty sure this is one reason music is so calming for me -- it's not just the air, but the deep magnetic stimulation :D
