" Most of our data was in a sub-stage of non REM called M2 sleep and that's kind of an intermediate sleep, and we saw a lot of these cerebrospinal fluid waves in this kind of intermediate stage of sleep. We also looked at lighter sleep, the kind of sleep you have very early in the night for a much smaller enough time, and we didn't see much of these waves. It's possible there's a little bit that we couldn't tell but definitely, once people went into this intermediate M2 stage then we saw a lot of the waves. "
