Aren’t smaller, better-connected brains more likely to be from an intelligent person? I’m not sure there’s a relationship between intelligence and brain size in general.
Also, huge head does not imply large brain inside the head.
missing big pieces usually makes it work less well.
folds and creases seem good?
Not too much fluid!
Not too little either!
front part seems pretty important for thinking.
middle too.
“stuff” in the brain is almost always bad for thinking. Like rocks and things. Neurons, blood and the right blend of fluids are great.
phrenology is pretty wrong. Like, super wrong.
Beyond that, we know a bunch of stuff about brains and neurons and how they all piece together, but just based on lookin’, we’re pretty bad at judging a person based on their head and brain.
Based on my neurology classes, I feel like we have some idea what some parts of the brain do. Obviously full on experiments would be unethical, but we can like, observe which neural pathways formed in people with the same life style (so Taxi Drivers have larger and more developed sections focused on navigation). We can observe what happens to people who take the same kinds of damage, and occasionally we get lucky and we can see what happens to people with grievous injuries or rare maladies. Also, we can do experiments on creatures like snails which far less complex brains.
The brain is certainly an interesting a weird black box, but we do have outs to learn some things
Oh, I forgot to mention that we can also do some weird experiments with rats. Teach a bunch of rats how to do a maze, or complete some task, and then surgically remove different bits of each of their brains.
Unless you really mess them up, they usually remember how to do the maze.
Yeah, brain plasticity is really fascinating. One of the guys I work with, its the only way to teach him anything. He had a heroin overdose like 15 years ago. He has basically no short term memory, but I’ve been able to get him to retain things via repetition. Mostly repetitive physical tasks, but social media, with advertisers constantly pinging him, has also been a very powerful reminder. He’s big into the EDM scene and he remembers events, both past and future, because social media keeps buzzing him and reminding him. I wish there was a way to harness that power for good.

Our brain shape science basically boils down to:

It’s why missing a chunk won’t make the neurologist definitely say it’s impaired someone’s intelligence.

It’s an extreme case, but definitely indicative of how visual examination is just not great for assessing brain function.

But obviously, I’ve never seen his brain before.
