During brain mapping, EEG scanners are used to measure electrical signals in different brain areas. These signals are statistically analyzed to see brainwave patterns. The EEG data is then recorded and processed by a computer software program. This data is compared against a reference database of other people’s EEG. A Quantitative EEG (qEEG) brain map helps us detect the brain area where there is too little or too much activity. It helps to identify amplitude, location and dysregulation. All these are required to understand adequate level of mental functioning. If electrical activity is outside the normal parameters, then it gives us indication towards possible problems. Brain mapping is a precursor to neurofeedback brain training as it helps in devising an appropriate training plan.        

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.

   

WHAT TO EXPECT FROM NEUROFEEDBACK SESSIONS?

A neurofeedback brain training session typically lasts for approximately 45 minutes. The time for training is 30 minutes and around 15 minutes is required to take your feedback and prepare the equipment for the session. Normally a minimum of 20 sessions is recommended to experience lasting benefits, although you will start noticing changes within the first few sessions itself. However, the number of sessions required depends upon the intensity and duration of the problem. Being consistent is extremely important  to experience the benefits. Every individual is different, and so is their brain. Therefore, neurofeedback therapy for memory improvement, ADHD, anxiety and depression is tailor-made to suit your specific needs.
