The human brain, its nervous projections, layers, and cortical blood vessels
Though we’re probably subconsciously aware of our brains on a day-to-day basis, most of us generally don’t pay much direct attention to them. Of course, lots can go wrong in the mind, resulting in mental illness, physical illness, and in the worst cases, death.
But aside from everything that can go wrong in the brain, did you know that the mind, despite being only 2% of the average body mass, uses almost 25% of the oxygen we consume, and over 70% of the glucose we ingest? It’s a tiny organ, but it manages almost everything outside of the parasympathetic nervous system, and it requires a relatively high energy input (especially compared to other organs in the body) just to function on a daily basis.
The cells in the brain require, on average, twice as much pure energy as other cells, just to function, and when you’re focusing hard on a big paper, or trying to brainstorm and be creative, your mind is in overdrive! Even if you haven’t moved in two hours, if you’re focusing hard on an essay and coming up with lots of great ideas, your lunch isn’t going to last long, with what your brain is demanding.
Since it’s not a muscle, and you’re not necessarily doing anything physical when you think, it can be hard to believe that the brain needs so much energy.
However, the cerebellum, and especially the frontal and prefrontal cortices (where our personality and “creative minds” exist, for the most part) demand more energy than our stomachs, livers, spleens, and kidneys combined! Depending on how your brain is wired, that fact can make it extremely exhausting to deal with other people, as you’re engaging your prefrontal cortex to a high degree. Thinking hard and being creative can sap your energy, too - that’s why I always had an apple or banana to eat midway through my morning courses!
Standard procedure for work preparation:
1. Open skull.
2. Remove brain.
3. Go to work.
4. Replace brain with coffee.
Math! You are gorgeous.

Good luck ever viewing the world the same way, ever again!

“You read any Greek myths, puppy? The one about the gorgon Medusa, particularly? I used to wonder what could be so terrible that you couldn’t survive even looking at it.
Until I got a little older and I figured out the obvious answer.

You needed more Lovecraft in your life. You may not have known it, but you did.

this is kinda creepy tho
The story behind this painting is very interesting, though. The artist’s mother was very sick, so the house was always filled a suffocating silence. This painting depicts him wanting to scream, but having to be silent, hence the anguished expression. In the whole painting you see figures in the background, one of which is his sister.
