Feasibility Study of Neurofeedback Training for Older Adults With Mild Cognitive Impairment

SMR neurofeedback training consisted to increase the synaptic strengths and sensitivity within this network. Electroencephalography signals for SMR/theta ratio training was recorded at channel Cz according to the International 10-20 system. Theta rhythm was also recorded and, in this case, SMR was stimulated while theta waves were suppressed. A 32 channels system (EEGDigitrack Biofeedback plus module, Inc Elmiko Medical) was used for SMR/theta neurofeedback training.
