When you think of a brain, you probably imagine that pink, wrinkly organ in your skull, but we don’t have to stop there! Neither the brain’s functions, nor its cells, are confined to the organ we normally think of as the brain.

You know what, I love Scishow. So many science channels have become clickbaity and more for entertainment. You guys truly teach us something more, and I absolutely appreciate it ❣️ You guys are amazing!

Yes.
Edit: I say this because I had a brain tumor as a kid that messed up my vision by crushing the optic nerve. I've been frustrated by the lack of interdisciplinary research between optomology and neurology. Cool video tho

"The eyes aren't protected by the skull."
Brow: "Am I a joke to you?"

The retina is considered an extension of the brain. I wouldn't call the retina "brain" but it is part of the central nervous system, alongside the brain and spinal cord. And there is a lot of research into using the retina as a diagnostic tool for neurological disease

Based on that, I feel like a “soft” definition would be that the brain has to have some manner of internal “calculation” to it. That is, if the nerve cells in this area are “read only”, they’re not part of the brain.

I would say it matters more where it originated that trying to rigidly define it.
Most likely eyes were light sensing spots on a more prototypical version of the brain of many land dwelling animals so yes, they're part of the brain in those cases.

I'm really enjoying our host Anthony Brown's delivery. And thanks to the rest of the team putting this topic together.

My whole body is a part of my brain!..🧠

Since becoming a gemmologist, I have understood the potential our eyes (and, therefore, our brains) have. It's incredible!
Edit: thank you for all the likes! I meant by understanding things like the types of lustre/luster.

Having sight issues and neurological issues and just interested in brains, this was really informative and easy enough for me to understand when I'm tired. Thanks, SciShow!

As someone with a mental illness, I am always pleased to see more about the interplay of the brain and other important neurological features and the rest of the body. Thanks again for a great video.

I was just explaining this earlier today. Loved this.

A brain is the only organ that named itself.

I'd use the definition where the mammalian brain is contained within a mammal skull. As far as I'm aware, all mammals share the same basic "framework" for a body. Brains may be implemented entirely differently in non-mammals, but in mammals it's pretty clear which part does the major processing. As far as I understand, there are neurons in the spinal column too which are related to reactions (if you burn your hand, you pull it away from the heat source faster than your brain can respond), but I wouldn't consider them as part of the brain.
7 |
This is fascinating. I wonder if nerve endings could be considered extensions of the brain seeing how some stimuli such as being burnt will produce a reaction to move your hand faster than your brain can process what had just happened.

Grant us eyes... Grant us eyes...!
It's always good to have eyes on the inside.....
5 |
Aren't eyes developmentally formed from brain tissue though? Or part of the eye at least. So that part should be considered part of the brain, I think.

This is a great well explained video and really interesting

Hope to see a SciShow Tangent episode on brains!
