“…The observed effects corresponded to an increase in the creative "effort" during the task that involved overcoming self-induced stereotypes, as significant differences between tasks were also observed in connection with the slight increase in theta power that also occurred in the parietal cortex, which could be considered associative memory engagement [49][50][51][52]. The data in the literature have demonstrated an increase in theta activity in the optimal conditions for stabilization of new hippocampus-dependent memories [53].…”

The study aimed to reveal task-related differences in story creation with and without the mental effort of overcoming self-induced stereotypes. Eighteen right-handed subjects (19.3 ± 1.1 years old) created stories. The subjects reported the formation of story plot stereotypes (as we call them: self-induced) during self-regulated creative production, which had to be overcome with the instruction to continue the story. Creative task fulfillment (without formed stereotypes-first stage of creation) was characterized by a decrease in the wave percentages of 9-10 Hz, 10-11 Hz and 11-12 Hz frequencies and EEG desynchronization (decreases in EEG spectral power) in the theta (4-8 Hz), alpha1 (8-10 Hz) and alpha2 (10-13 Hz) frequency bands in comparison with the REST (random episodic silent thought) state. The effortful creation task (with overcoming of self-induced stereotypes-second stage of creation) was characterized by increases in waves with frequencies of 9-10 Hz, 10-11 Hz, 11-12 Hz in temporal, occipital areas and pronounced EEG synchronization in alpha1,2 frequency bands in comparison with the free creation condition. It was also found, that the participants with the higher originality scores in psychological tests demonstrated increased percentage of high frequencies (11-12 Hz in comparison with those who had lower originality scores. Obtained results support the role of alpha and theta frequency bands dynamics in creative cognition.

“…These ndings are consistent with the previous study which suggested the speci city of target frequency bands. 24 Theta/low-beta protocols can effectively improve episodic memory but low-beta/theta NFB protocols can not be seen the same trend 12 . The results of the theta/low-beta PSD and theta PSD did not increase over the course of the second stage linearly, similar to previously-reported ndings that the brain activities increase unstable during training 10,11,25,26,27 .…”

“…We designed the theta/low-beta NFB protocol and introduced auditory stimuli based on previous studies which proposed with visual stimuli 12 . Additionally, we referred other studies suggested that theta waves may be involved in the consolidation of episodic memory 12,23 for our training design. We considered that auditory feedback results in less disturbance than visual stimulation and allows participants to concentrate on appropriately regulating their cognitive control.…”

“…In particular, episodic memory, or the retrieval of encoded information in a short time, was markedly improved after NFB training 10 . However, the effects of NFB training on long-term memory are not wellunderstood as most studies regarding episodic memory include short timeliness 11,12 and do not report the forgetting rate.…”

“…The frontal midline theta waves, like the hippocampal theta waves, play a role in the processing of memory 20,21 . Theta/beta NFB training has been used to treat attention conditions 22 , and previous studies suggest that the theta/low-beta NFB protocol can be used to affect the performance of episodic memory 12 .…”

Understanding and improving memory is vital to enhance human life. Theta rhythm is associated with memory consolidation and coding, but the trainability and effects on long-term memory of theta rhythm are unknown. This study investigates the ability to improve long-term memory using a neurofeedback (NFB) technique reflecting the theta/low-beta power ratio on an electroencephalogram (EEG). Our study consisted of three stages: First, the long-term memory of participants was measured. In the second stage, the participants in the NFB group received three days of theta/low-beta NFB training. In the third stage, the long-term memory was measured again. The NFB group had better long-term memory than the control group and significant differences in brain activity between episodic and semantic memory during the recall tests were revealed. These findings suggest that it is possible to improve the long-term memory abilities through theta/low-beta NFB training, which also improves episodic and semantic memory.
