Abstract
The Brainwave Entrainment (BWE) hypothesis suggests that it is possible to induce neuromodulation through non-invasive auditory or visual stimulation, enhancing cortical activity at the stimulation frequency. Many studies have investigated the BWE effect of binaural beats (BB), applying stimulation within EEG frequency bands to modulate cognitive functions or elicit specific mental states. However, evidence on the effectiveness of BB in altering brain activity remains inconsistent. The present study introduces a protocol to evaluate both short- and long-term effects of BB stimulation. The primary aim is to determine whether brain activity during and after BB exposure differs from resting conditions, and to explore changes within the frequency band targeted by stimulation.
The study involved 11 university students (7 males and 4 females, mean age 24.8 ± 1.6 years) over a two-week period including three acquisition checkpoints, each lasting 20 minutes
