Abstract
Retrieval of positive Autobiographical Memory (AM) has been reported to increase positive emotions in healthy population. Evidence suggests that positive AM retrieval tasks are correlated with synchronisation of frontal Theta rhythms (4-8Hz). The present study has developed the Electroencephalography (EEG) based Neurofeedback (NF) protocols to promote voluntary elevation or up-regulation of positive AM retrieval related Theta rhythms over F3, Fz, F4 electrode sites (10-20 System). The protocols were evaluated with a human participant in 10-day NF training. It observed that the average amplitude of observed Theta rhythms in each NF regulation block gradually increased over days of training and most was prominent at Fz electrode site. Furthermore, a larger peak at 6Hz was present in the spectrum of the observed Theta with later trial day suggesting up-regulation of Frontal Midline Theta (FmT) rhythms.
