Neurofeedback for OCD: Training Circuits That Get Stuck
Dr. Andrew Hill demonstrated live neurofeedback training while exploring how specific brain circuits contribute to obsessive-compulsive patterns—and how we can train them. This wasn't just about clinical OCD, but the broader spectrum of "sticky" thinking patterns that trap attention and energy.
The FZ-PZ Protocol: Targeting the Error-Detection Circuit
Hill started with a theta down-training protocol at FZ minus PZ—frontal to posterior parietal sites. This electrode placement targets the anterior cingulate cortex, which acts as the brain's error-detection system.
"The anterior cingulate is hyperactive in OCD," Hill explained while setting up his electrodes. "It's constantly scanning for errors, for things that don't feel right. When this circuit gets stuck in overdrive, you get the classic OCD loop: detect error, perform ritual, temporary relief, then right back to error detection."
The protocol inhibits theta (4-7 Hz) and high beta (20+ Hz) while providing no rewards—pure down-training. This approach calms the hypervigilant error-detection system without overstimulating it.
Question: Why use FZ-PZ instead of other placements for OCD?
This montage captures both anterior and posterior cingulate activity. The anterior cingulate detects errors and creates the "something's wrong" feeling. The posterior cingulate handles self-referential processing—the "this affects me" response. OCD involves both circuits firing together in a feedback loop.
SMR Follow-Up: Building Inhibitory Control
The second protocol targeted SMR (12-15 Hz) at CZ—the sensorimotor strip. This wasn't coincidental.
"SMR strengthens thalamocortical inhibition," Hill noted. "It's the same circuit that generates sleep spindles. When you can produce robust SMR while awake, you're literally training your brain to inhibit unwanted activity."

The key insight here: OCD isn't just about overactive error detection—it's about poor inhibitory control. The brain can't stop checking, can't stop the ritual, can't disengage from the loop.
Technical Setup Insights
Hill demonstrated real-time troubleshooting that many home users face:
- Amplifier connection issues: "You restart the amp, usually restart the software. Pretty common."
- Signal quality over placement precision: "EEG is easy when set up properly, impossible when it's not. Clean signal matters more than perfect placement."
- Electrode paste application: Proper electrolyte contact makes or breaks the session.
Question: How critical is exact electrode placement?
You have about 1 cm tolerance in every direction. Signal quality—thin, clean EEG traces without muscle artifact—matters far more than millimeter precision. This makes home training accessible.
The OCD Spectrum: Beyond Clinical Diagnosis
Hill expanded the discussion beyond DSM-defined OCD to include "sticky" thinking patterns many experience:
- Repetitive thought loops
- Checking behaviors (email, locks, phone)
- Mental rumination cycles
- Perfectionism that interferes with completion
"There's a spectrum," he explained. "We're not just talking about clinical OCD, but any pattern where attention gets trapped and can't disengage."
Delayed Effects of Frontal Training
Question: Why don't I feel changes immediately after frontal protocols?
Frontal neurofeedback produces delayed effects—12 to 48 hours later. Unlike sensorimotor protocols that show immediate changes, frontal circuits integrate new patterns slowly across broader network connections. The anterior cingulate coordinates with multiple brain regions, so consolidation takes time.
This is crucial for OCD training. Don't expect immediate relief. The circuit changes build over days and weeks.
Practical Takeaways
- Start with SMR training to build basic inhibitory control before targeting frontal error-detection circuits
- Combine protocols: Down-training overactive circuits while up-training regulatory ones
- Expect delayed effects from frontal protocols—patience is essential
- Signal quality trumps precision—focus on clean electrode contact over perfect placement
- Home training is viable with proper equipment and basic technical troubleshooting skills
The session highlighted how neurofeedback approaches OCD not as a fixed disorder, but as trainable circuit patterns. The brain that learned to get stuck can learn to flow freely again.
