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 ([Formula: see text] = 0.10, p = 0.076). Similarly, memory score improvements at a greater significance ([Formula: see text] = 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[Formula: see text] value (0.9838) within the 40 Hz group between sessions as well as mood score when compared across the entire frequency group cohort.
在此，我们通过一项探索性试点研究提供证据，表明对于一个由9名参与者组成的队列，通过使用伽马40赫兹夹带频率，可以改善情绪、记忆和认知。参与者被分为三个双耳夹带频率组：40赫兹、25赫兹和100赫兹。在为期4周的时间里，参与者总共参加了八次夹带频率课程，每次课程进行两次。此外，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分钟双耳节拍刺激前后进行。情绪评估分数分别从第1、4和8次课程中收集。对于伽马40赫兹夹带频率组，我们观察到认知分数平均有所提高，在实验结束时，从平均75%提高到85%，具有较弱的统计学意义（[公式：见原文] = 0.10，p = 0.076）。同样，记忆分数的提高具有更大的显著性（[公式：见原文] = 0.05，p = 0.0027），从平均87%提高到95%。关于情绪分数，在所有组中都观察到负相关，这意味着由于分数较低与情绪升高相关，情绪总体上有所增加。最后，相关性分析显示，与整个频率组队列相比，40赫兹组内各课程之间以及情绪分数之间的R[公式：见原文]值更强（0.9838）。
