> During the intervention week, participants wore an electroencephalogram (EEG)-enabled headband that delivered acoustic pulses timed to arrive anti-phase with alpha for 30 min (Stimulation). During the Sham week, the headband silently recorded EEG.

Now, I might just be misreading this, but doesn't this sound like an awful way to blind the trial?

During the experimental week, participants evidently had the headband beep (okay, blast pink noise) at them for half an hour. For the sham week, it didn't. It seems like participants would be able to tell whether their headband is active or whether they're in the placebo week.

It seems to me that the better control would have been to still give participants pink noise pulses at approximately the same frequency, but without regard for the measured alpha wave cycles.

I wonder if Functional Near-infrared cerebral spectroscopy[1] could be used instead of an EEG to make this work, it might be a lot easier, and cheaper... you could sew it all into a hat. Apparently the main thing you need is a Pulse Oxygen Sensor.[2]

If workable, amazingly cool. I can turn overall 10:00pm and it's stacked zz until 5am. My partner can be hanging on to past midnight and it's pissing her off these last decades. Melatonin gives her horrid florid dreams and restless legs and nobody wants to get hooked to temazepam.

I've had periodic exploding head syndrome when I lie on my neck wrong. Random phantom noises like a single slap on the wall, gunshots, explosions, breaking noises, and crashes that aren't there but seem like they could be.

Interesting. I wanna see this tested with and without Ambien

I need one of these asap please.
