40 Hz light and sound flickering therapy, are games weakening gamma entrainment
I'm using the AlzLife app on a new iPad Pro. The app flickers light and/or sound at 40 hz and can be used with or without games.
It's a struggle for me to sit for an hour and look at a flickering light so I typically play the games on the app. Ke et al found that an external distraction, listening to a podcast, weakened gamma entrainment to a 40 hz flickering sound in healthy controls https://pubmed.ncbi.nlm.nih.gov/40938966/ suggesting attention to the stimulation plays a role in efficacy. This has me wondering if playing the games on the app could blunt gamma entrainment and I'd be better served by staring at a flickering screen instead.
I'd love to hear peoples' thoughts on this. Is anyone monitoring 40 hz stimulation entrainment using an EEG wearable like MUSE?
