What is qEEG brain mapping?
A qEEG (quantitative electroencephalogram) is a non-invasive, roughly 20-minute assessment that records your brain's electrical activity through a sensor cap and compares it against a normative database. The result is a color-coded “map” showing which areas of your brain are over- or under-active — objective data that can help explain symptoms and guide a personalized, drug-free treatment plan.
What does a qEEG brain map measure?
Your brain communicates through electrical rhythms called brainwaves. A qEEG measures the strength, balance, and timing of those rhythms across the whole head, in several frequency bands — each associated with a different mental state. Dysregulation in a specific band, in a specific region, often lines up with the symptoms a patient is experiencing.
Delta (1–4 Hz)
Deep-sleep waves. Excess Delta while awake may be associated with brain injury or cognitive fog.
Theta (4–8 Hz)
Drowsy, inward-focused waves. Elevated Theta is frequently observed in attention and focus difficulties.
Alpha (8–12 Hz)
Calm, idle-engine waves. Imbalances may relate to mood, motivation, and how easily you relax.
SMR & Beta (12–30 Hz)
Alert, engaged thinking waves. Excess high Beta often accompanies a brain stuck on high alert — a pattern seen with anxiety.

What happens during a brain mapping session?
The entire visit is simple, painless, and comfortable — most patients are surprised how uneventful it feels. Here is the step-by-step process at Neuron Connect.
A sensor cap is fitted
A soft cap with 19 sensors is placed on your head with a bit of conductive gel. Nothing enters your body — the sensors only listen.
Your brainwaves are recorded
You sit comfortably for about 20 minutes while activity is recorded with your eyes open and eyes closed. It is painless and non-invasive.
Your data is analyzed
The recording is processed with NeuroGuide, a normative database developed by Dr. Robert Thatcher, and compared against typical activity for your age.
You review the map with our team
A clinician walks you through the color-coded results, what they may mean for your symptoms, and whether a personalized neurofeedback plan makes sense.
How is qEEG different from an MRI or CT scan?
MRI and CT scans photograph the brain's structure. A qEEG measures the brain's function— how well regions are working and communicating moment to moment. That is why a person can have a “normal” MRI after a concussion and still struggle with focus, mood, or sleep: the structure looks fine, but the function is dysregulated. The two types of imaging answer different questions and are often complementary.
MRI / CT scan
Shows: Brain structure — anatomy, bleeds, tumors, and physical damage
Doesn't show: How brain regions are actually functioning and communicating
qEEG brain map
Shows: Brain function — the electrical activity and timing of brain regions in real time
Doesn't show: Structural details (which is why the two are often complementary)
This functional evidence is one reason qEEG has become valuable in personal-injury and car-accident cases, where standard imaging may miss the effects of a concussion or TBI.
How do brain map results guide neurofeedback?
The map identifies which regions and frequency bands are outside typical ranges. Those findings become the training targets for neurofeedback therapy: in each session, sensors read your brainwaves in real time and give your brain gentle visual and auditory feedback whenever it shifts toward a healthier pattern. Over a typical protocol of 20–40 sessions, this repetition is designed to help the brain learn to self-regulate — without medication.
Because the plan is built from your own data, training targets differ from patient to patient — a child working on focus and attention trains differently than an adult recovering from a concussion.

Neurofeedback sessions reward healthier patterns; progress is tracked and the plan adjusts.
Common questions about qEEG brain mapping
Is qEEG brain mapping safe?
Yes. A qEEG is completely non-invasive — the sensor cap only records the electrical activity your brain naturally produces. Nothing is transmitted into your head, there is no radiation, and there are no known side effects. The most common complaint is a little gel left in your hair afterward. It is safe for children, adults, and seniors, and is frequently used as a first assessment step precisely because it carries so little risk.
How long does a brain mapping session take?
Plan for about 45–60 minutes at the clinic. The brainwave recording itself takes roughly 20 minutes — a few minutes with your eyes open and a few with your eyes closed — while the rest of the visit covers cap setup, a brief symptom review, and scheduling your results consultation. The analyzed map is usually reviewed with you at a follow-up visit, where a clinician explains the findings in plain language.
How should I prepare for a qEEG?
Arrive with clean, dry hair and skip styling products like gel or hairspray, which can interfere with the sensors. Try to sleep normally the night before and avoid extra caffeine right before the appointment, since both can shift your brainwave patterns. If you take prescription medication, keep taking it as prescribed — just tell our team what you take so it can be considered when your map is interpreted.
What conditions can a brain map help with?
A qEEG does not diagnose conditions by itself, but the patterns it reveals can help explain symptoms associated with ADHD and focus problems, anxiety, depression, PTSD, concussion and traumatic brain injury, and sleep difficulties. The map shows where activity differs from typical patterns for your age, which helps our team design a personalized, drug-free neurofeedback plan targeted at those specific areas rather than guessing from symptoms alone.
Does insurance cover qEEG brain mapping?
Coverage varies by insurer and plan, so our team verifies your specific benefits before you commit to anything. Neuron Connect also accepts several other payment paths: HSA and FSA funds, Arizona ESA scholarship funds for qualifying families, and attorney liens for personal-injury patients — meaning car-accident and injury patients can often begin care with no upfront out-of-pocket cost while their case is pending. See our ways-to-pay page or call (602) 888-1012 for specifics.
