🧠 I’ve Been Going Down a Rabbit Hole About GABA…
I've been learning more about GABA because it's one of the reasons I became so interested in GABA tea in the first place.
And the more I learn, the more I realize that calling GABA the brain's “calming chemical” really doesn't explain what it's doing.
I used to think of GABA almost like one pathway that basically tells the brain, okay, calm down.
That's not really how it works.
GABA is the primary inhibitory neurotransmitter in the adult brain. In simple terms, it acts a lot like a braking system. It can make a neuron less likely to fire.
But this is where it got interesting to me.
There isn't just one GABA road.
GABA-producing neurons are spread throughout the nervous system, and those inhibitory signals are being used in all kinds of different circuits.
So depending on where that brake is being applied, GABA can be involved in regulating things like:
🧠 stress, fear and anxiety-related circuits
😴 sleep and wakefulness
⚡ the balance between excitation and inhibition
💪 movement and muscle control
🎯 attention and sensory processing
🧠 learning and memory
🧪 neuroendocrine and hormonal signaling
❤️ autonomic functions like breathing and cardiovascular regulation
And then I learned something else I didn't realize before: GABA receptors aren't only found on neurons. Researchers have found GABA signaling in parts of the immune system too, and they're studying its role in immune and inflammatory processes.
That sent me down another rabbit hole. 😂
Another thing that surprised me is that inhibition doesn't automatically mean “calm.”
If GABA puts the brakes on a wake-promoting neuron, that can help support sleep.
If it inhibits activity within certain fear and arousal circuits, it can help control how active those circuits become.
But GABA can also inhibit a neuron that was already acting as a brake. In that situation, you can actually end up with more activity downstream. That's called disinhibition.
So now I think about GABA differently.
It's not simply the brain's “relaxation chemical.”
It's more like a regulatory braking system that helps control when, where and how strongly different neural circuits are allowed to fire.
That's what I mean when I talk about the GABA Highway.
And since I've already gone this far down the rabbit hole 😂, I think I'm going to start breaking down some of these individual roads—stress, sleep, the nervous system, hormones and even the emerging research around GABA and inflammatory signaling.
🌿 Education first. The more I understand the pathway, the more I understand why GABA fascinated me in the first place.
