Neuroscientist Rachel Langford explains how HEG (Hemoencephalography) neurofeedback trains the brain by improving oxygenation in the prefrontal cortex. Using a simple “hot and cold” feedback system—much like guiding a child to a hidden object—HEG provides real-time signals that help the brain learn exactly what to do. During HEG training, a sensor band placed on the forehead measures changes in blood flow and oxygen levels in the prefrontal cortex. As oxygen increases, the trainee receives immediate visual feedback—such as a flying brain animation gaining height and points. When oxygen drops, the animation slows or descends, indicating the brain is moving away from the target. Through repeated, real-time feedback, HEG guides the brain to consistently raise oxygenation levels. Over time, trainees typically see measurable improvements in focus, sustained attention, and reduced distraction, making HEG a powerful tool for cognitive enhancement.

Neuroscientist Rachel Langford explains how neurofeedback training actually works using QEEG brain mapping. Once your unique brain profile is established, training begins with non-invasive sensors that measure your brain activity—EEG electrodes or oxygen sensors—without sending anything into your brain. During sessions, your brain receives real-time feedback in a friendly, visual way. For example, the video you watch on the screen gets brighter and louder as your brain hits its targets and darker and quieter when it moves away from them. This “hot and cold” feedback helps your brain learn to strengthen healthy patterns. Rachel breaks down how this process works for different protocols and training goals, showing how QEEG-guided neurofeedback can help optimize your brain function safely and effectively.

The video explains the concept of neurofeedback (NF), described by the clinic’s neuroscientist Rachel Langford as a form of physiological brain training. Langford explains that neurofeedback is essentially a way to teach the brain to function more efficiently. Just like physical exercise strengthens muscles, neurofeedback “takes the brain to the gym,” helping it learn to self-regulate and perform better. This training targets conditions or situations where the brain struggles to operate effectively, ultimately giving the individual a lifelong physiological skill that supports improved mental and emotional functioning.

Join neuroscientist Rachel Langford as she breaks down the fascinating world of neurofeedback training. In this video, Rachel explains how the process begins with a detailed brain map (EEG), analyzing over 20 areas of the brain. She walks through assessments of cognitive processing, emotional regulation, language, sensory processing, sleep patterns, and communication between brain networks. Once your unique brain profile is understood, the training begins—a journey of 40–50 sessions designed to establish healthy neural patterns. Throughout the process, progress is carefully monitored to track changes and improvements in brain function over time. Whether you're curious about neuroscience or considering neurofeedback for yourself, this video offers an insightful look into how your brain can be trained for optimal performance.
