Bluebird Neurofeedback
When clients arrive for their first qEEG brain map appointment at Bluebird Neurofeedback in Portland, the most common question is some version of “so what is this thing going to tell you about me?” This is a fair question. A quantitative EEG (qEEG) is the foundation of every neurofeedback program we run, and it shapes the protocol your brain will train with for the next several months. Let’s break it down.
What the recording captures
A qEEG records the electrical activity of your brain through 19 small sensors arranged on the scalp in a soft cap. We collect about 30 minutes of resting-state data while you sit quietly with your eyes open, then with your eyes closed. The sensors are picking up the tiny voltage fluctuations that happen as networks of neurons fire together.
Those fluctuations are then sorted by frequency band. Delta (the slowest), theta, alpha, beta, and gamma waves each have characteristic roles in regulating the brain. A healthy brain produces all of them, but in different amounts in different regions, depending on what it is doing. Sleeping brains look different from focused-attention brains. Anxious brains look different from depressed brains. The qEEG is what lets us see and quantitatively measure what your brain is doing.
The color maps you may have seen
Most clinics will hand you a colorful topographic map like the one below. It is a head-shaped diagram with red, yellow, and blue zones showing where activity is high or low compared to age-matched peers from a normative database. These auto-generated maps are useful as a quick overview that is easy to understand. They are not, however, the deepest layer of information in the recording.
Two clients can have nearly identical topographic maps and very different underlying patterns. The map shows you the rough geography. It does not show you what the brain is actually doing in each region.
Why we read the raw waveforms
At Bluebird, we read each client’s raw EEG waveforms directly. These are the actual time-series traces from each electrode, tracking different regions of the brain. We read these alongside the topographic maps generated by the qEEG data from your brain.
This matters because raw waveforms carry information that the auto-summary smooths away:
- Phenotype patterns. Researchers such as Jay Gunkelman and Robert Johnstone described EEG “phenotypes.” These are recognizable electrophysiological patterns in how brain activity is organized. These show up in the shape and rhythm of the raw trace, not in the color map. A frontal slow phenotype and a thalamocortical phenotype can look similar on a topographic summary but call for very different training protocols.
- Artifacts vs real signal. Eye movements, muscle tension, jaw clench, and a noisy sensor can all create what looks like elevated activity on a color map. Without reading the raw trace, you cannot tell whether the “high beta” in a frontal region is anxiety or a clenched jaw.
- Coherence and timing. How regions of the brain communicate with each other is visible in the relative timing of their waveforms. A topographic summary tells you what is loud where. The raw trace tells you whether two regions are talking to each other, talking past each other, or out of sync.
When the protocol is built from the raw waveform read, training is matched to your brain’s actual pattern rather than to the closest match in a database.
What we are looking for, in plain language
When we review your qEEG, the determinations we are making include:
- Where is your brain over-aroused? This is where there is too much fast-frequency activity, which is often associated with anxiety, racing thoughts, and sleep difficulty.
- Where is it under-aroused? This is too much slow-frequency activity in regions that should be alert, often associated with attention and focus difficulties.
- Where are the timing mismatches between regions? This is often from coherence issues, associated with cognitive and emotional regulation difficulties.
- What phenotype pattern best fits the raw trace? This shapes the entire training plan.
The answers to those questions become your training protocol. This is where we determine which frequencies to up-train, which to down-train, which regions to target, and in what order. This is distinct to you, your brain, and your goals.
Why this matters for your training results
A generic color-map summary does give the important data necessary to craft an effective protocol. At Bluebird, we integrate the raw EEG, qEEG maps, artifact review, phenotype-informed interpretation, as well as the client’s history and goals. That gives us a more individualized basis for deciding which frequencies to reward or inhibit, which regions to train, and how to sequence the work. Neurofeedback is a learning-based process, and outcomes vary, but a careful, detailed assessment helps make the training plan much more targeted from the start.
If you have been wondering whether neurofeedback might fit your situation, the qEEG is where the conversation actually starts. Until your brain is mapped, anything we tell you about training is guesswork.
