Neurofeedback is a training technique that helps individuals learn how to self-regulate brain activity with the help of neurological feedback provided by sensory devices. There are many types of neurofeedback, including: EEG neurofeedback (associated with brain waves), HEG neurofeedback (associated with blood flow), and real-time fMRI neurofeedback (associated with neural activation). Each of these neurofeedback …
Autism is a neurodevelopmental disorder noticeable in childhood characterized by impaired communication skills and difficulty forming relationships or bonds with others. Those with autism may lack empathy, dislike physical contact, and may be especially sensitive to loud noises, bright lights, or certain smells. Currently there is no cure for autism, and many individuals diagnosed with …
MRI (Magnetic Resonance Imaging) is a brain scanning technique that incorporates both magnetic fields and radio waves. It is currently considered the most advanced form of neuroimaging technology and can be used to detect traumatic brain injuries, strokes, and/or tumors. The MRI was invented in the early 1970s by Paul C. Laurterbur, but has since …
People with lifelong anxiety disorders often have genetic polymorphisms that cause abnormal activation of various neural circuitry and changes in neurotransmission, provoking excessive fear. While fear in appropriate situations such as getting attacked by a lion is beneficial in that it helps us survive by giving us superhuman abilities (e.g. endurance, strength, thinking), many people …
Neurofeedback is a technique that involves training an individual to consciously alter the electrical activity (brain waves) within their brain. The technique can be used as an intervention to improve symptoms of a variety of psychological conditions, including depression. Individuals with depression tend to have abnormal brain wave activity compared to those without any preexisting …
HEG (Hemoencephalography) is a specific neurofeedback technique that trains users to consciously regulate cortical blood flow. The practice is based off of the idea that with enough “neurological feedback” (provided by an HEG device) a person becomes able to consciously control an unconscious process (blood flow). Normally it would be impossible to detect whether blood …
Neurofeedback is a practice devised to optimize the electrical activity within a person’s brain a.k.a. adjust their brain waves. It is based on the premise that abnormal electrical activity in certain regions of the brain may contribute to various psychological conditions and may compromise mental performance. The goal of neurofeedback is to correct electrical abnormalities …
