Usually, the level of asymmetry between the left and right brain caused by the difference between left and right brain functions is seen in an EEG analysis, as we see in the literature. A prerequisite for optimizing brain function is appropriate symmetry between the left brain and the right brain. In this paper, we developed a neurofeedback system to improve emotional disorders, such as anxiety and depression, and to optimize the brain function. Our experiment confirmed an enhancement in the symmetry of left/right brain activities and EEGs in each training section. A comparison of the results for the first and third weeks of the experiment showed a considerable increase in alpha and beta waves, and we found that the symmetry between the left and right brain activities was improved. The system might be applied in various fields, including education programs improving concentration for children and medical treatments to improve depression and insomnia for adults.
