Effects of Neurofeedback in Cognitive Deficit in Patients With TBI

LoRETA Z-score NF will be conducted using a 19-lead cap (Electrocap, Inc), which will be placed on the head according to the standard approach of the international 10-20 system with linked ear and ground reference. After the caps will be less than 5 kΩ. During each session, the participants will sit in front of a computer screen on which predesigned games or animations related to the LoRETA Z-score training are played and instructions regarding the inhibitory and reward aspects of the training are taught.

The goal of theta/beta NF is to increase the beta power(13-20 Hz) and simultaneously inhibit the theta power (4-8 Hz) relative to a baseline assessed at the beginning of a training session. The electrodes will be placed on Fz and Cz with a linked ear model(A1). The study will use both visual and auditory feedback. Each participant will sit in front of a computer screen on which predesigned games or animations related to the training criteria are played and instructions regarding the inhibitory and reward aspects of the training are taught. The threshold will be set according to 5-min baseline EEG measurements before each session. The thresholds are the mean amplitude of the beta and the theta in 5-min baseline EEG.
