Neurofeedback training of frontoparietal alpha rhythm enhances episodic memory
Neurofeedback Training (NFT) of brain rhythm is an operant conditioning paradigm through a video or audio interface
and has been widely used in clinic. Episodic memory is a prerequisite for successful life functioning. This study aims to
explore trainability of alpha NFT with a sham-controlled experimental design and effect of alpha NFT on episodic memory.
Participants were randomly assigned into a control group receiving feedback of 4-Hz amplitude randomly selected from 7-20
Hz or an alpha group receiving feedback of 8-12 Hz amplitude. The NFT contained 12 sessions and each session consisted of
6 min blocks. Picture recognition task with identifying exact shape and size of objects was used to assess episodic memory.
Topographic distribution of trained alpha rhythm was categorized through the whole-head EEG recording. The Alpha group
exhibited a linear increase in amplitude and duration of alpha rhythm throughout the NFT exclusively. The Alpha group
exhibited significantly higher amplitude and longer total duration of alpha rhythm compared with those of the control group.
Accuracy of the picture recognition task in the Alpha group was significantly improved after NFT compared with that of the
control group. In particular, participants with increased alpha rhythm which primarily distributed in bilateral frontoparietal
region exhibited significantly linear trend between alpha duration and accuracy of the picture recognition task. The evoked
alpha rhythm in the occipital region seemed to be no effect on accuracy of the picture recognition task. The present study
provides additional evidence on the trainability of alpha rhythm through NFT and also identifies functional localization of
alpha rhythm in the frontoparietal region on enhancement of episodic memory. Our results suggest a non-pharmacological
intervention on memory enhancement throughout a NFT of alpha rhythm.
Biography
Fu-Zen Shaw has his interest in establishment of animal models of epilepsy and fibromyalgia and also provides valuable non-pharmacological interventions
for ameliorating seizures through closed-loop deep brain stimulation or for enhancing wellbeing of healthy people and patients with insomnia or mild cognitive
impairment through self-training of brain rhythms. Recently, he has developed a neurofeedback platform to train alpha rhythm with a sham-controlled group
to validate controllability, specificity and independence of the neurofeedback training. He also provides convinced evidence about trained alpha rhythm on
enhancement of both working memory and semantic episodic memory.
