Laboratory of Neurobiofeedback and Biofeedback

The Neurobiofeedback Lab, in collaboration with EEG Info, the largest research and educational institution in electroencephalography and neurofeedback, is equipped with the latest 39-channel electroencephalographs, evoked potential recording system (ERP), neurofeedback (conventional and modern ILF method) and biofeedback. In this laboratory, the electrical activity (signal) of the brain is recorded by surface electrodes by an EEG device. The most important principle in this method is to install the electrode in the standard defined place. After decomposition (spectroscopy), the initial signal recorded at different frequencies can be seen. The amplitude of these frequencies in comparison between healthy and sick people according to the location of the electrode shows differences that are more or less in the sick person than the healthy person. It should be noted that this difference in frequency range can be corrected by the neurofeedback system.


Neurofeedback is a system that tries to teach a person a kind of self-regulation by recording the brain's electrical waves and giving feedback. Feedback is typically provided to the individual through sound, image, and touch. It is through this feedback that a person realizes whether he or she has made a proper change in his or her brain activity. The common neurofeedback method is able to individually and individually modulate the amplitude spectra of alpha, beta, theta and delta frequencies with neural feedback. This process can be done in terms of time in 20 to 40 45-minute sessions. But the latest neurofeedback (ILF) system, infrared low-frequency neurofeedback, has the ability to regulate the amplitude of brain waves by modifying a single frequency (below 1 Hz) that carries all alpha, beta, theta, and delta frequencies over a period of 20 years. Practice for 15 to 20 minutes. This system is the only system that, in addition to visual and auditory feedback, also provides tactile feedback to the individual. A biofeedback system is a system that works with a function similar to a neurofeedback system, but by recording heart rate, blood oxygen and body temperature and giving feedback, tries to teach a person self-regulation so that a person can increase his body efficiency by achieving physical relaxation.

Currently, joint international research projects between the Research Institute of Medical Sciences and Technologies and other faculties of Shahid Beheshti University in collaboration with EEG Info in areas such as artificial intelligence, increasing attention and reducing reaction time to visual and auditory stimuli, reducing stress Tinnitus and Parkinson's disease are being treated. In the mentioned projects, an attempt is made to find the abnormalities of the electroencephalogram in different diseases according to the location and information of the recording signals (frequency and amplitude) in comparison with healthy people, and the correct understanding of the electroencephalographic disorders of patients and the correct treatment of neurofeedback. to be presented.
