Neurofeedback Games to Improve Cognitive Abilities

Neurofeeback training can be used to enhance cognitive abilities related to multi-tasking such as working memory, attention, etc. We propose and implement a neurofeedback system which includes a number of neurofeedback training algorithms and a Shooting game. To make neurofeedback training more effective, an Individual Alpha Peak (IAP) frequency and individual alpha bandwidth are calculated and applied in the algorithms. We do preliminary study on the effectiveness of the proposed neurofeedback system with three subjects taking 6 sessions each. The neurofeedback protocols based on the power of individual upper alpha or beta-1/theta ratio training are used. Our hypothesis is that after the neurofeedback training by playing the Shooting game, the individual alpha peak frequency increases. The results show that all subjects had a higher individual alpha peak frequency after the training that indicated an enhancement of the subjects´ cognitive abilities related to multi-tasking.
