What Is a qEEG? A Guide to Brain Mapping


When it comes to understanding brain function, a quantitative electroencephalogram, or qEEG, is one of the most powerful tools available. Often called a “brain map,” a qEEG provides a detailed picture of how your brain is working and helps guide personalized neurofeedback training.

What Exactly Is a qEEG?

A qEEG measures the electrical activity in your brain using sensors placed on your scalp. While a traditional EEG simply records brainwaves, a qEEG takes it further by analyzing the data and comparing it to a database of healthy, age-matched brains. This process shows where your brain activity is typical and where it may be outside the expected range.

What the Brain Map Shows

A qEEG provides a colorful, visual report that highlights brainwave patterns linked to how you think, feel, and perform. For example, it can reveal areas of the brain that are:

  • Overactive, leading to issues like anxiety or racing thoughts

  • Underactive, connected to challenges like poor focus or low mood

  • Imbalanced, contributing to sleep problems, impulsivity, or emotional regulation difficulties

Why a qEEG Is Important

The brain map acts like a roadmap for your brain health. Instead of guessing, practitioners can see exactly which areas need support. This makes neurofeedback more precise and personalized. It also helps track progress over time, showing how the brain changes with training.

What the Process Is Like

A qEEG is safe, painless, and non-invasive. Sensors are gently placed on your head while you sit still for about 20 minutes with your eyes open and then closed. Nothing enters your body. The sensors only measure your brain’s natural electrical signals. Once the recording is complete, the data is processed and turned into a detailed report.

The Bottom Line

A qEEG gives you a unique window into your brain’s activity. By identifying patterns linked to focus, mood, sleep, and overall performance, it helps create a personalized plan for neurofeedback training and other brain-based strategies. If you’re curious about why you feel the way you do, a brain map can provide answers and guide the path to better brain health.
