Here we provide evidence with an exploratory pilot study that through the use of a Gamma 40 Hz entrainment frequency, mood, memory and cognition can be improved with respect to a 9-participant cohort. Participants constituted towards three binaural entrainment frequency groups: the 40 Hz, 25 Hz and 100 Hz. Participants attended a total of eight entrainment frequency sessions twice over the duration of a 4-week period. Additionally, participants were assessed based on their cognitive abilities, mood as well as memory, where the cognitive and memory assessments occurred before and after a 5-min binaural beat stimulation. The mood assessment scores were collected from sessions 1, 4 and 8, respectively. With respect to the Gamma 40 Hz entrainment frequency population, we observed a mean improvement in cognitive scores, elevating from 75% average to 85% average upon conclusion of the experimentation at weak statistical significance ( $$\alpha$$ = 0.10, p = 0.076). Similarly, memory score improvements at a greater significance ( $$\alpha$$ = 0.05, p = 0.0027) were noted, elevating from an average of 87% to 95%. In pertinence to the mood scores, a negative correlation across all populations were noted, inferring an overall increase in mood due to lower scores correlating with elevated mood. Finally, correlation analysis revealed a stronger R $$^2$$ value (0.9838) within the 40 Hz group between sessions as well as mood score when compared across the entire frequency group cohort.

伽马夹带频率影响情绪、记忆和认知：一项探索性试点研究


在这里，我们提供了一项探索性试点研究的证据，表明通过使用 Gamma 40 Hz 夹带频率，9 名参与者的情绪、记忆和认知可以得到改善。参与者分为三个双耳夹带频率组：40 Hz、25 Hz 和 100 Hz。参与者在 4 周的时间内总共参加了两次 8 次夹带频率课程。此外，还根据参与者的认知能力、情绪和记忆进行评估，其中认知和记忆评估在 5 分钟双耳节拍刺激之前和之后进行。情绪评估分数分别从第 1、4 和 8 节中收集。对于 Gamma 40 Hz 夹带频率群体，我们观察到认知得分平均有所改善，在实验结束时，认知得分从平均 75% 提高到平均 85%，统计显着性较弱 ( $$\alpha$$ = 0.10, p = 0.076）。同样，记忆力得分也有更显着的改善（$$\alpha$$ = 0.05，p = 0.0027），从平均 87% 提高到 95%。与情绪分数相关，所有人群都发现负相关，推断由于分数较低与情绪升高相关，因此情绪总体上升。最后，相关性分析显示，与整个频率组队列相比，会话之间 40 Hz 组内的 R $$^2$$ 值 (0.9838) 以及情绪得分更强。
