40 Hz Gamma Binaural Beats
40 Hz is the most scientifically studied gamma frequency. It is the signature frequency of working memory, moments of insight, and -- in groundbreaking research -- may help clear amyloid plaques associated with Alzheimer's disease. This frequency represents the frontier of neuroscience and brainwave entrainment.

The Science Behind 40 Hz
40 Hz gamma is the most extensively studied entrainment frequency. Jirakittayakorn & Wongsawat (2017, Cognitive Neurodynamics) found that 40 Hz gamma binaural beats enhanced working memory performance and increased gamma-band EEG power over frontal and parietal regions. In a landmark study, Martorell et al. (2019, Cell) demonstrated that 40 Hz gamma stimulation reduced amyloid plaque burden and improved cognitive function in Alzheimer's mouse models, spurring ongoing human clinical trials at MIT and other institutions. While the Alzheimer's research is still early-stage, the memory and cognitive benefits are well-supported.
