WHAT IS NEUROFEEDBACK? |
|
At the end of 1960-1970’s, scientists considered the possibility of reconditioning and restimulating the pattern of cerebral waves. Some studies started as trainings, with the increasement of cerebral alpha activity, increasement that was meant to produce a growth in relaxation, while others, starting with UCLA, were focused on uncontrolled epilepsy. This cerebral wave exercise is called eeg-biofeedback or neurofeedback. The cerebral waves appear on different frequencies, some are fast and others quite slow, named after the classical names of EEG bands: delta, theta, alpha and beta, and are measured in cycles/second or Hz. Every one of us has a certain amount of these brainwaves, which are found in different parts of the brain. For example, delta brainwaves will occur when cerebral areas disconnect in order to take up nourishment, and it can also be associated with learning disabilities. When a person feels his mind clouded, drowsy, then there are more delta and slow theta brainwaves, and when people are inattentive (unfocused) to the surrounding things and daydreaming, there is more theta present. When someone is exceptionally tense or anxious, an excessively high frequency of beta brainwaves is often present. People with attention deficit / hyperactivity disorder (ADD / ADHD), with cranial traumatism, stroke, epilepsy, chronic fatigue syndrome and fibromyalgia, have the tendency to possess an excessive amount of slow brainwaves (mainly theta and sometimes alpha waves excess). When the amount of slow brainwaves in the frontal lobe (the executive part of the brain ) is excessively high, it becomes difficult to focus, to control the behavior and/or the emotions. These people usually have trouble concentrating, memorizing, controlling their impulses and emotional states, or have hyperactivity problems. They cannot concentrate very well and have a diminished intellectual efficiency.
