NEUROFEEDBACK THERAPY: WHAT IS BRAIN MAPPING?
NEUROFEEDBACK: BIOFEEDBACK FOR YOUR BRAIN
As with biofeedback, neurofeedback is used to improve your health and performance, with a particular focus on mental and emotional aspects of your well-being. Through the use of tools that provide real-time displays of your brain's patterns and responses, qEEG-based neurofeedback is used to train your brain and teach it to self-regulate its functions.
KNOW THE DIFFERENT BRAINWAVES
Neurons in the brain communicate with each other by electrical exchange. This electrical activity is displayed in the form of brainwaves which can be observed using electroencephalogram (EEG).
Delta waves are the slowest brainwave. These are the most relaxing brainwaves. A delta wave appears when you’re asleep. It measures from 0-4 Hz and has the highest amplitude.
Theta waves have greater amplitude. The frequency range is 5-7 Hz. Theta state is seen during light sleep or deep meditation. In this state you may experience vivid visualizations, profound creativity, flow of ideas and exceptional insight.
Alpha waves are produced naturally when you close your eyes and relax. Alpha brain waves are in the frequency range of 8 to 13 Hz. During this state your brain is said to be awake and relaxed.
Beta waves are known as high frequency low amplitude that are commonly observed while we are awake. The frequency of beta waves is 14-40 Hz. These involve conscious tasks such as critical thinking, writing, reading, and socialization seen in day-to-day lives.
Gamma waves are the fastest of brain waves with high frequency. These are observed when processing information from different brain areas simultaneously. Gamma brainwaves pass information rapidly and quietly.
Research indicates brainwave patterns are linked with emotional and neurological conditions. Brain mapping shows brainwaves associated with over-arousal in certain areas result in fidgeting, impulsivity, hyperactivity and agitation. Under-arousal in certain brain areas are linked with poor concentration, insomnia, and day-dreaming. Hence, brain mapping for neurofeedback therapy gives us a picture of a brain’s current strengths and weaknesses.
