Dominant brainwave frequencies offer a window into how the brain operates in various states—from deep sleep to intense focus. In neurofeedback, knowing how to interpret these frequencies can make the difference between a generic approach and one that truly meets a client’s needs. This post explains what dominant frequency means, how it's identified on a qEEG, and why it matters when tailoring neurofeedback protocols. With practical examples and evidence-backed training strategies, it shows how clinicians can use this knowledge to promote healthier brain function and measurable progress.
