57 Neuroscience Puns That Are Nerve-Wrackingly Funny

Neuroscience puns are the only category of wordplay where I genuinely can’t tell if I’m being clever or if my prefrontal cortex is just flattering itself. I’ve been collecting these for way too long. Some of them are brilliant, some of them are crimes against language, and a few exist in a quantum state where they’re somehow both.

1. The Classic Opener

I lobe you very much.

That’s it. That’s the text you send. Screenshot it, post it, tattoo it on your temporal lobe. I don’t care. It’s perfect and I won’t hear otherwise.

2. Firing on All Cylinders

Why did the neuroscientist hire a new assistant? She wasn’t sure about this new neuron, but he was firing on all cylinders.

3.

Let’s synapse a picture, it’ll last longer.

(This one works better out loud. Most of the good ones do, tbh.)

4. The Axon Incident

My axon keeps acting on my impulses, and honestly? That tracks. I’ve never once made a calm decision at a drive-through.

5.

When it comes to intelligence, grey matter really matters.

6. The Dopamine Hit

I told my friend about my latest research breakthrough and she said “that’s some dope-a-mine idea!” and I’ve never felt more seen by another human being. This is the pun I’d put on my tombstone. No notes. Absolute peak wordplay. The dopamine I got from hearing it was, fittingly, enormous.

7-9. Rapid Fire Neurotransmitter Round

• Grab a GABA, it’ll calm you down.
• Sarah’s tonin’ up her mood with serotonin.
• Glutamate helps neurons glue-to-mate. (I’m sorry. I’m so sorry.)

10.

Does your neural net work?

This one plays differently now than it did in like 2019. Every tech bro in a Patagonia vest has ruined the word “neural” for me.

11. The Hippocampus Question

Where does a forgetful hippopotamus go to study? The hippocampus. Obviously. My seven-year-old nephew told me this one and I’m not above stealing from children.

12.

It’s mind over grey matter.

13. One I’m Genuinely Proud Of

“Am I gonna love ya, amygdala, or am I just gonna feel fear?”

Read that out loud. Slowly. It works phonetically in a way that took me an embarrassing amount of time to construct. The amygdala processes both love and fear responses, so the science even checks out. I peaked here and everything after this is downhill.

14.

Sarah-bellum, can you help me with my balance? The cerebellum joke nobody asked for but everyone needed.

15. The Action Potential

This young neuron has a lot of action potential.

Double meaning. Clean delivery. Works as an Instagram caption if you’re graduating from a neuro program. You’re welcome.

16.

Why did the neuroscientist break up with the biologist? There was no chemistry, only electricity.

Okay that’s barely a neuroscience pun. I’m stretching. I know I’m stretching.

17. The Grey Area

Student after a confusing lecture: “It’s a grey matter, but I think I understand.”

18.

Neuroscientists are always a-head of the game.

19. The Myelin Sheath Ballad

What did the uninsulated axon sing? “Myelin, my Lynn, why don’t you insulate me?” This is the kind of pun that only works if you imagine it being performed at a sad karaoke bar by someone three drinks in. Which, to be fair, is where most neuroscience puns belong.

20.

The brainstem is the stem of all brain activity. That’s not even clever, it’s just… true. Sometimes the pun writes itself and you just have to respect it.

21-22. The Scanning Suite

“E-E-Gee, that’s a lot of brain waves!” said the technician, staring at the EEG.

Meanwhile in the next room: “I’d love to PET-scan my brain.” Affectionately. Like a golden retriever.

23.

You’re really getting on my nerves.

(Technically this is just… a sentence. But it counts. It COUNTS.)

24. The Cortex Core

The cortex is the core-techs of the brain. I workshopped this for zero seconds and it shows.

25.

I just had a great brain wave!

Quick tangent, does anyone else find it weird that we use “brain wave” to mean a sudden good idea, when actual brain waves are just constant electrical noise? Like, your brain is always waving. It never stops. That’s not special. That’s just Tuesday. Anyway.

26. The Cleft Note

I’m cleft with a feeling of understanding after studying the synaptic gap.

This one’s for the people who actually remember what a synaptic cleft is. If you got it, you got it. If you didn’t, go reread chapter 3.

27.

That lecture was real brain food.

28. The Plasticity Pitch

The brain’s plasticity makes it a plastic city of change, constantly rebuilding, remodeling, knocking down walls. Your brain is basically an HGTV show that never got cancelled.

29.

What a sense-ation!

every sensory neuron, all the time, about everything

30. The Dendrite Dilemma

A neuron walks into a bar looking for a good spot to receive signals. Bartender says, “Is this dendrite the den-right place for information?” The neuron leaves. Can’t blame it.

31.

I got a head start on my neuroscience homework. Caption-ready. Go use it. I don’t need credit.

32. Acetylcholine, My Beloved

I need a set of choline to get my muscles moving.

This pun requires you to know that acetylcholine is the neurotransmitter responsible for muscle contraction at the neuromuscular junction, and honestly if you know that, you deserve this pun more than most people deserve anything.

33-35. The Disorder Cluster

I’m not gonna pretend these are good. They’re functional. Like the brainstem.

• My brain is in dis-order. (Get it? Disorder? Dis-order? I’ll see myself out.)
• All this studying is causing a brain drain.
• I hope my brain doesn’t catch a dis-ease, you know, a lack of ease.

36.

That’s a very cerebral thought.

37. The One That Haunts Me

“It’s glia to me that these cells are important.”

Glia. Clear. GLIA. CLEAR. It’s supposed to sound like “clear to me” and I will die on this hill even though literally nobody has ever laughed at this one. Glial cells are the unsung heroes of the nervous system, they outnumber neurons, they maintain homeostasis, they form myelin, and this is the best pun I could come up with for them. They deserve better.

38.

Don’t stim-u-late me too late. I’m trying to sleep.

39. Long-Term Potentiation Vibes

I told my partner that our relationship is like long-term potentiation, the more we fire together, the stronger our connection gets. They said that was the nerdiest thing I’ve ever said. They’re not wrong. Hebb’s rule applies to love, I don’t make the rules. Neurons that fire together wire together, and so do people who share neuroscience puns at 11pm.

40.

The neuron fired, but it didn’t get fired. Lucky.

41.

Neuroscience is truly mind-blowing.

(Low-hanging fruit. I grabbed it. No regrets.)

42. The MRI Moment

Em-are-eye, I see what you did there.

I’ve been told this only works in an American accent. I’ve done no research to confirm or deny this.

43.

I’m trying to pave new neural pathways, which is just a fancy way of saying I started learning guitar at 34.

44. The Impulse Buy

“I’m pulsed to make a decision,” said the neuron, buying another thing it didn’t need off Amazon at 2am. We’ve all been there. The sodium channels open and suddenly you own a bread maker.

45-46.

Signal the neurons to fire! Or, as the brain commander put it: “Sign-all the neurons!”

We need a brain trust to solve this problem. Emphasis on the trust. My neurons have been unreliable lately.

47.

This neural pathway is the only path way to success.

Bad? Yes. Moving on.

48. The Wernicke Wobble

I asked my friend with a linguistics background to help me write a pun about Wernicke’s area and she said, “I could, but you wouldn’t understand it.” Which is… actually a perfect Wernicke’s aphasia joke? Wernicke’s area handles language comprehension, so damage there means you can produce speech but it’s meaningless. She’s funnier than me and I hate it.

49.

My brain cells are in the habit of inhibiting. Inhibit-habit. In-habit of inhibiting.

I’ve stared at this too long and now none of these words look real.

50. The Neurotransmitter Update

This new-row-transmitter is sending all the right signals. You know the one. Fresh out of grad school. Eager. Suspiciously optimistic about their research timeline.

51.

Can you re-call that memory? Because I’ve been calling and calling and it’s going straight to voicemail.

52. Broca’s Brag

Broca’s area is where you broke a sentence together.

Ngl that’s a stretch. Broca’s area handles speech production and that pun handles nothing well. But it’s staying in because I need representation for the speech production regions and this is all I’ve got.

53.

That’s a head-y topic.

54. The Favorite Child

What did the photographer say to the brain cells? “Let’s synapse a picture, it’ll last longer.” Wait, I already used this one. Did I? I think I did. This is what happens when you write 60 puns in one sitting, your hippocampus starts filing noise complaints. I’m keeping this duplicate as a monument to my own cognitive decline.

55.

My psycho-logy professor is a real mind reader. I mean, technically that IS the job description.

56-58. The Home Stretch Cluster

• Neuroscience, it’s new-row-science, always discovering something new.
• I need to put on my thinking cap. (Not a pun. Just solid advice.)
• My brain can compute complex problems, which is wild because it can’t remember where I put my keys ten seconds ago.

59. The Schwann Song

What did the peripheral nerve cell sing at its retirement party? Its Schwann song.

Schwann cells produce myelin in the peripheral nervous system. If you knew that already, congratulations, you’re the target audience for this entire blog and I appreciate you more than dopamine appreciates a reward pathway.

60.

Don’t be so nerve-y about your nerves. A neurologist said that to me once. I think she was joking. I hope she was joking.

61. The Resting Potential

Someone asked me what I’m doing this weekend and I said “maintaining my resting potential” and they thought I meant relaxing but I meant -70 millivolts.

Instagram caption material right there. Only about four people will get it and those are the only four people whose opinions matter.

62.

The white matter really matters for speed. Like the autobahn of your brain, except the speed limit is determined by how thicc your myelin sheath is.

63. A Stroke of Something

It took a stroke of genius to understand this topic. Phrasing. I know. In neuroscience, “stroke” means something very different and I should’ve thought harder about this one before committing it to text.

64.

I’m left with a lot on my mind. Specifically the left hemisphere. It’s doing most of the talking.

Okay I think my brain is genuinely running out of puns, which means my Broca’s area has finally unionized and is demanding better working conditions. Fair enough.

65. The Closer

What’s a neuroscientist’s favorite way to end a conversation?

“I’d love to keep talking, but I’ve lost my nerve.”

That’s all I’ve got. My neurons have officially stopped firing. If you made it this far, your sustained attention network deserves a raise, or at least a GABA supplement.
