AI Article Synopsis
- Several studies have explored the effects of binaural beat (BB) stimulation on brain activity, focusing on alpha wave responses, but limited research has been done on how factors like gender and age impact these effects.
- The study involved 23 healthy adults (11 males and 12 females, ages 20-29) who underwent 10-Hz BB stimulation through specific auditory tones in each ear, with alpha wave activity analyzed across different brain regions.
- Results indicated a significant increase in alpha power across most brain areas following BB stimulation, but no significant differences were observed between genders in alpha wave generation.
Article Abstract
Background: Several studies have continuously investigated FFRs using binaural beat (BB) stimulations and their related effects. However, only a few studies have investigated the differences in BB stimulation effects according to basic demographic characteristics, such as gender and age.
Objective: This study aimed to determine the alpha wave activity after a 10-Hz BB stimulation and subsequently identify differences according to gender across all brain areas (frontal, central, parietal, temporal, and occipital areas).
Methods: A total of 23 healthy adults (11 male and 12 female), aged 20-29, participated in the study. For the 10-Hz BB stimulation, pure tone auditory stimuli of 250 and 260 Hz were given to the left and right ear, respectively. Through a power spectrum analysis of the phase-excluding BBs (non-BBs) and phase-including 10-Hz BBs (α-BBs), the alpha power at each brain area was estimated. These values were compared using a mixed-design ANOVA.
Results: With the exception of the temporal area, all other brain areas showed a significant increase in alpha power for α-BBs compared to those of non-BBs. However, the difference according to gender was not significant.
Conclusion: The results indicated the lack of gender effects in alpha wave generation through a 10-Hz BB stimulation.

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.
Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.
Fast periodic visual stimulation (FPVS) coupled with EEG has been used for a decade to measure word-selective neural responses in (a)typical adults and developmental readers. Here, we used this FPVS-EEG approach to evaluate suitable and optimal stimulation frequency rates for prelexical and lexical word-selective responses and relate these rates to typical reading speed and interindividual variability in reading performance. EEG was recorded in 41 healthy adults who viewed words inserted periodically (1 Hz) at four different stimulation frequency rates (4 Hz, 6 Hz, 10 Hz, and 20 Hz).

Background: Rhythmic median nerve stimulation (MNS) at 10 Hz has been shown to cause a substantial reduction in tic frequency in individuals with Tourette syndrome. The mechanism of action is currently unknown but is hypothesized to involve entrainment of oscillations within the sensorimotor cortex.
Objective: We used functional magnetic resonance spectroscopy (fMRS) to explore the dynamic effects of MNS on neurometabolite concentrations.

The effect of optical stimulation at a frequency of 10 Hz (OS) on temporal parameters of sensorimotor activity in healthy subjects (n=32) was studied. The expression of the activation response was determined by the ratio of spectral power values (SPα2, μV) of the high frequency (10-13 Hz) subrange of the α-rhythm of the initial EEG with closed and opened eyes and the frequency of the maximum α-peak (IAPF). A test for simple motor reaction time was performed under normal and OS conditions.

Background: As a non drug and non invasive therapy, both transcranial alternating current stimulation (tACS) and transcranial direct current stimulation (tDCS) may modulate cortical rhythms and serve as potentially effective approaches to cognitive decline in Alzheimer's disease (AD). However, studies using animal models of AD are quite limited.
Methods: This study investigates the aftereffects of tACS and tDCS on brain EEG activity and associated exploratory behavior in normal aged and APP/PS1 transgenic mice (15 months old).
