BrainTap headset (light + sound + binaural beats) and more broadly the “brainwave entrainment” field.

✅ Studies showing potential benefits
Here are several that lend support to the idea of light/sound/binaural-beat entrainment influencing brain function.
1. Systematic Review: Light & Sound Stimulation
A review titled “Stimulation by Light and Sound: Therapeutic showing that light + sound stimulation could induce favourable mental states, improved learning/athletic performance, and some physical/mental health benefits. 
• The authors conclude that the technique “can be applied … in a safe and noninvasive way” but also note that the research base is quite limited. 
• Good to know: this gives broader context that the general method is being explored scientifically.
2. Study on Binaural Beats & Memory in Adolescents
A study titled “Effect of Brainwave Entrainment Using Binaural Beat Stimulation on Short-Term Memory” found positive effects on working memory in adolescents after listening to a 40 Hz binaural beat for five minutes compared to control. 
• This suggests that auditory entrainment alone (binaural beats) may improve certain cognitive functions (e.g., short-term memory).
• Caveat: small sample size, short duration, limited scope.
3. Study on Modulatory Effect of Light + Binaural Beats
A study “Modulatory Effect of Association of Brain Stimulation by Light and Binaural Beats in Specific Brain Waves” examined the combined effect of LED lights + binaural beats on different populations (elderly, children with autism/intellectual impairment, etc.). 
• They found modulatory effects on alpha and SMR brain waves.
• This is more in line with what a device like BrainTap claims (light + sound + brainwave entrainment).
• Still, this is more “brain-wave changes” rather than proven long-term functional outcomes.
4. Recent Paper on Optical Light Stimulation & Entrainment
A 2025 paper, “Alertness assessment by optical stimulation-induced brainwave entrainment…” showed that rhythmic light stimulation (optical) can entrain brainwaves and that machine learning classifiers could detect alertness changes. 
• Demonstrates technical capacity for entrainment via light stimulation in humans.
• Doesn’t necessarily show long-term functional benefit, but shows the mechanism is plausible.
5. Research on 40 Hz (Gamma) Stimulation for Alzheimer’s/Neurodegeneration
A well-publicised line of research from MIT and others shows that 40 Hz light+sound stimulation (gamma-band) in mice reduced Alzheimer’s-related hallmarks (amyloid/tau, neuron death) and improved cognition.
