Thanks for looking.
Firstly, I am nowhere near biologist, just a student, so my apologies if this isn't a "good" question.
Background:
So I was searching about intelligence, brains and computers, and noted 2 videos, one where a person tries growing human neurons to be connected to a computer, and a mouse brain connected to a supposed robot car.
It made me curious, if there's any major difference between neurons between species.
Question
Is there a difference between a human's brain cells compared to other species?
For the sake of the question, it will be limited to a mouse or a dolphin's, but if you can bring more info from another kingdom, it would be really welcomed.
I'll be really grateful if you coupled it with some illustrations!
Note:
This question is NOT about brain-size, but rather, a single unit of whatever that makes a brain, brain.
