Is Neurofeedback different then Biofeedback?

  • Neurofeedback, also called EEG-Biofeedback, is biofeedback for the brain. 

  • Biofeedback monitors and measures certain bodily processes like heart rate, muscle tension, blood pressure, skin temperature, and amongst others. 

  • Neurofeedback works by providing feedback to the brain so it can heal itself through neuroplasticity. This is done through computer games, sounds, or even watching a show. Neurofeedback is done through positive feedback also called operant conditioning. 

What are brainwaves?

At the foundation of all our thoughts, behaviors, and emotions is the communication between neurons within our brains. Information taken from our external environment and then is processed by our central nervous system (CNS).  


Our brainwaves are produced by synchronized electrical impulses from trillions of neurons communicating with each other. When these neurons are firing impulses, they create a brain wave which can then be recorded on an EEG. Brainwave speed is measured in Hertz (cycles per second). Brainwaves can be then categorized based on their level of activity or frequency. 


What are the main types of brainwaves?

Delta Brainwaves: Delta brainwaves are slow and they are produced in deepest mediation and dreamless sleep. Regeneration and healing are stimulated during this state, this is why sleep is essential to the healing process. If this brain wave is suppressed, it leads to an inability to rejuvenate the body and revitalize the brain, and poor sleep. Delta is prominently seen in brain injuries, learning problems, inability to think, and ADHD. 

Theta Brainwaves :Theta brainwaves occur most often in sleep. Theta is our doorway to learning and memory. When we are awake, excess theta levels can result in feels scattered or day-dreamy, which is commonly found in ADHD. 

Alpha Brainwave: Alpha brainwaves are dominant during quiet thought and is responsible for being present at that time. It is the resting state for the brain and aid in the calmness, alertness, mind/body integration, and alertness. 

Beta Brainwaves: Beta Brainwaves signifies our normal waking state of consciousness when our attention is directed towards cognitive tasks and the external environment. Beta wave is dominate when we are alert, attentive, problem solving, or decision making. Beta brainwaves are even further broken down into Low beta, beta, and High Beta. Having continual high Beta leads to anxiety and difficulty relaxing.  

Gamma brainwaves: Gamma brainwaves have the highest frequencies of any brainwave. They are associated with peak concentration and high levels of cognitive functioning. Low levels of gamma activity have been linked with learning and memory difficulties.
