when referring to one person’s. It’s common in some circles, I do it all the time.
“Ow, my brains hurt”.
Peace,

Is it okay to say "brains"
No, tomorrow you must say "BBBBBBBRRRRRRRAAAAAIIIIIIINNNNNNNSSSSSSSSSS!!!"
Makes me wonder, would Braniac be afraid of zombies?
One of the “Gumbys” on one of the Monty Python records complains “My Brain Hurts!”
It sounds pretty goofy, which is, I’m sure, why they had the character say it.
So, sure, you can say it if you want. If you don’t mind sounding like a Gumby.
there we go, with the freakin’ zombies again. I guess they could be one of the circles I mentioned. 
No, I want to say “My brains hurt”. But if I can sound like a Gumby, I’ll change.
My brain hurts
My brain hurts
My brain hurts
My brain hurts
My brain hurts
There, I got it.
I suppose it depends how many brains you have, and only you know that.
Would you also say “Penises ensue”?
I have two testicles. That’s a closer comparison to brains, is it not?
“Testicles ensue”.
See!
Oooooh! Unless you’re a quantum zombie!
Then you have to say, “BRAAAAAAAAAAANES!”
Sure, it’s okay. You won’t get in trouble or anything.
I don’t think so–unless they need a little fiber.
By Jove, I’ve got it!
Michael Meyers is a quantum zombie!
You always know how fast he’s going: He never runs and he never slows down, so he’s always going at a constant walk. Therefore, you can never know where he is. His major weapon is the Heisenberg Uncertainty Principle… his major weapons are the Heisenberg Uncertainty Principle and a big knife… and the element of surprise… I’ll come in again.
It’s okay as long as you have more than one. Take me, for instance. I have the brain of a rocket scientist. I keep it in a jar in the bathroom.
They built a new brain research institute over near Kendall Square and someday I’d love to go in there in full Gumby kit and say “are you the brain specialist?”
Technically, we have brains, cerebrum, cerebellum and medulla oblongata. Those would be high brain, mid brain and low brain.
Mmmm… I’d tend to disagree: one organ, three constituent parts. But I have seen ‘hindbrain’ and ‘brainstem’ enough to take your point.
My understanding of English usage is that we have one brain (=organ of the body) which is composed of “brains” (=the organic substance comprising it). Occasionally in reference to instinctive or reflexive reactions, various ‘Anglo-Saxon’ terms corresponding to the Latinate technical terms for brain constituents will be used, such as ‘brainstem’ or ‘forebrain’.
Or you could have just linked to this.
My understanding of English usage is that when zombies say, “BBBBBBBRRRRRRRAAAAAIIIIIIINNNNNNNSSSSSSSSSS!!!,” they want more than one brain. When you refer to one person’s brain, it’s singular, individual components thereof notwithstanding.
I blew his brains out.
His brains were leaking out.
His brains were all over the place!
It’s pretty common to use the plural even when talking about one person’s brain.
Yep. But the significance here is the substance, which idiomatically is the plural. Compare guts. “I have an ache in my gut” (=abdominal organ, unspecified) vs. “The knife thrust ripped out his guts” (=intestines, abdominal contents).
