Neurofeedback – Wikipedia, the free encyclopedia
Neurofeedback (NFB), is also called neurotherapy, neurobiofeedback or EEG biofeedback.
It uses realtime displays of electroencephalography to illustrate brain activity, often with a goal of controlling central nervous system activity.
Sensors are placed on the scalp to measure activity, with measurements displayed using video displays or sound.
Proponents claim that neurofeedback is an effective intervention for a number of problems where brain control is difficult (e.g. ADHD and epilepsy), and research is being performed to investigate the effectiveness of the technique for treating autism, headaches, insomnia, anxiety, substance abuse.]
In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20-40 minutes, as recorded from electrodes placed on the scalp.
