This paper provides Neurofeedback training by which the brain learns to function more efficiently. This work aims to provide real-time information to the Central Nervous System as a feedback in the form of visual cues.20 subjects (age between 20 and 30) were trained to improve their concentration and cognitive skill. In this paper, high frequency beta (β) and low frequency theta (θ) components have been extracted from the EEG signals, picked up using single channel electrodes of 10-20 international lead system. The acquired signals are then processed and their power spectral components are integrated. β/θ ratio is calculated and when the desired value is reached, the brain is rewarded in terms of visual cues and music interruption. Problems involving brain deregulations are addressed and concentration of the subject enhances. This procedure is painless, non-invasive, provides permanent results and can be repeated whenever necessary. The training can be done using LabVIEW software. The subject learns to improve areas of mental, physical and emotional functioning.
