Theta Neurofeedback of the Parahippocampal Gyrus for Memory Enhancement: A Preliminary Study

Resective surgery for mesial temporal lobe epilepsy (MTLE) carries the potential risk of memory decline. Neurofeedback (NF) which regulates brain activity and function, may be a promising solution for improving memory function. We constructed a memory-NF system using theta band power of electrocorticograms from the parahippocampal gyrus (PHG) and evaluated it with a preliminary study. As a result, we observed changes in theta-range oscillatory activity in PHG during NF training, and gained important insights for further developing the memory-NF system for memory enhancement.
