You've probably had blood work done, or a physical exam, or maybe even an MRI. But have you ever had a map made of your brain's electrical activity? A qEEG brain map does exactly that, and what it reveals can change how you understand your health entirely.
What Is a qEEG?
qEEG stands for quantitative electroencephalography. It is a form of brainwave recording that goes several steps beyond a standard EEG. While a traditional EEG simply records raw brainwave signals (typically to check for seizure activity), a qEEG applies sophisticated mathematical analysis to that data, comparing your brain's patterns at 19 different sites against a large normative database of healthy brains.
The result is a detailed, color-coded visual map showing which areas of your brain are overactivating, underactivating, or dysregulated in specific brainwave frequencies. This is the closest thing that currently exists to a "GPS of your brain."
What the Brain Map Measures
Your brain produces electrical activity across five main frequency bands, each associated with different mental states and functions:
- Delta (0.5–4 Hz), Deep sleep, healing, tissue repair
- Theta (4–8 Hz), Daydreaming, creativity, drowsiness, excess linked to ADHD and brain fog
- Alpha (8–13 Hz), Calm, relaxed focus, the brain's "idle" state
- Beta (13–30 Hz), Active thinking, focus, engagement, excess linked to anxiety
- Gamma (30+ Hz), Peak cognitive processing, information binding
The qEEG maps all five bands across all 19 sites, revealing patterns that explain your specific symptoms with a precision that no questionnaire or symptom checklist can match.
What the Brain Map Can Reveal
Different conditions leave distinctive signatures on the brain map. While no two brains are identical, certain patterns consistently appear:
- ADHD: Excess theta in the frontal lobes; low beta in attention centers
- Anxiety: Excess high-beta activity; hyperactivation in stress-processing regions
- Depression: Left frontal underactivation; excess alpha in regions governing mood and motivation
- Trauma / PTSD: Hyperactivation in threat-detection areas; disrupted connectivity
- Post-concussion: Slow-wave activity in areas of impact; asymmetrical patterns
- Long COVID: Excess slow-wave activity in attention and cognitive areas
What the Appointment Looks Like
A qEEG brain mapping session at Deep Brain Training typically takes 60–90 minutes. You'll sit comfortably while Dr. JoJo places a soft sensor cap on your head. The cap contains 19 small sensors that rest gently against your scalp, there are no needles, no pain, and no radiation. You'll be asked to rest with eyes open and then eyes closed while the system records several minutes of brainwave activity at each site.
Dr. JoJo then analyzes the data and prepares your brain map report, a detailed document that includes color-coded maps, an interpretation of your specific patterns, and a proposed neurofeedback protocol designed around your findings.
Why the Brain Map Matters Before Starting Neurofeedback
Without a brain map, neurofeedback is educated guesswork. With a brain map, it becomes precision medicine. The map tells us exactly which sites to train, which brainwave frequencies to up-train or down-train, and in what sequence to proceed. This precision is the difference between a generic treatment and a protocol built specifically for your brain.
Most clients are surprised by what their brain map reveals, and find it deeply validating to see a visual explanation for symptoms they've lived with for years.
