The benefits of Neurofeedback® training include enhanced alertness, memory, sleep and mood, to name a few. Neurofeedback is a type of biofeedback whereby a person is trained or taught to self-regulate the electrical activity of his/her brain by means of immediate or real-time feedback (visual, auditory or tactile). The electrical activity of the brain or EEG we record during a neurofeedback session is obtained non-invasively by placing sensors on the scalp and earlobes. Since the 1960s, research has shown that the brain's electrical patterns are modifiable, be it by operant conditioning or because of the nervous system's capacity to orient and find patterns.
In frequency training, activity in different EEG frequency bands is decreased or increased according to a person's needs, usually established by a QEEG analysis or clinically, by an expert provider. In non-linear dynamic training models, the activity of the brain is trained to reduce its emergent variability across frequencies ranging from 1 to 42 Hz. More importantly, neurofeedback capitalizes on the fact that the human brain is highly plastic and can change across the lifespan.
Understanding the underlying principles of neurofeedback is an exciting, ongoing and active topic of research. Training with neurofeedback has been shown to modify cortical excitability and intracortical function. Neurofeedback studies have revealed paradigm-specific effects on attention and memory processes, as well as performance in a variety of real-life situations, improving sleep, relaxation, anxiety and depression, to name just some of the effects.
In our office, we work with both traditional frequency-based neurofeedback (clincially or QEEG guided) as well as with a non-linear dynamic model.
