Cortical area · one in each half of the brain
Caudal anterior cingulate cortex
Also called Dorsal anterior cingulate cortex (dACC), Anterior midcingulate cortex
Your inner "oops" detector: spotting mistakes, conflicts and the sting of pain.
The caudal anterior cingulate sits in the middle of the cingulate belt, above the corpus callosum. It watches for mistakes and clashing choices, and helps decide whether a goal is worth the effort. It also helps create the unpleasant feeling part of pain. When it senses trouble, it rallies other brain areas to focus harder.
Where it is
On the inner surface of each half of the brain, above the front and middle of the corpus callosum, deep beneath the top of your head toward the front.
What it does
Catching errors
It reacts within a split second after you make a mistake, helping you slow down and do better next time.
Handling conflict
It notices when two responses compete, like reading the word "red" printed in blue ink, and calls for more focus.
Weighing effort
It helps decide whether a reward is worth the work, and keeps you going when a task gets hard.
The sting of pain
It helps create how unpleasant pain feels, separate from where it hurts.
Think of it as a smoke alarm combined with a coach: it beeps when something is going wrong and then pushes you to try harder or change strategy.
Works with
- InsulaTogether they form the salience network, which flags what matters most right now.
- Dorsolateral prefrontal cortexAfter it spots a problem, this area steps up control to fix it.
- Superior frontal gyrusIt works with motor planning areas here to adjust or stop actions.
- Locus coeruleusIt can signal this brainstem nucleus to release noradrenaline, sharpening alertness when the stakes rise.
- Midline and intralaminar nuclei of the thalamusThese thalamic nuclei carry pain and arousal signals up to it.
When it goes wrong
Pain that bothers less
After a small surgical lesion here for severe chronic pain, many people say they can still feel the pain but it no longer bothers them as much.
Loss of drive
Damage to this area on both sides can cause akinetic mutism: the person is awake but rarely moves or speaks on their own, as if their drive has been switched off.
OCD
In OCD, this area is part of an overactive brain circuit that may feed the urge to check and repeat, and it is one target of surgery for severe cases.

Surprising facts
- Brain-wave recordings pick up an "error signal", thought to come from around here, within about a tenth of a second after a mistake.
Where the name comes from
"Caudal" comes from the Latin "cauda", meaning tail, so it means toward the back. It is the back part of the front half of the cingulate belt.
