Very cool. My daughter has a brain shunt due to complications of spina bifida and so we’re thinking of cerebrospinal fluid on a regular basis. As a layman I guess there’s a particular cerebrospinal fluid pressure you want, and that being too high or too low causes issues? Apparently the shunt just drains into her belly so I also found that interesting. Too high and she’ll have terrible headaches and an “alien” head (sorry, don’t mean offense by that but it’s what I’m trying to avoid for my child) and I don’t know what would happen with too little, maybe someone could tell me. Probably not good I’m assuming.

I frequent some FB groups for parents of children with SB and am shocked at how large some people let their kids heads get without consulting with or complaining to a doctor.

Re falling asleep during MRI - I was a subject in a study where for about an hour you had to lie in a machine and repeatedly indicate which of two pictures depicted a larger object. They said subjects falling asleep was a big problem! I find sleeping very difficult and even I was feeling extremely drowsy after 45 mins of lying down and establishing "elephants are bigger than mice. Houses are bigger than shoes. Trees are bigger than flowers. Cars are bigger than dogs etc etc etc"

Cool video, but it would be much cooler if there was some idea of the timescale (i.e. how often do these waves occur?). I doubt that it's shown real-time; perhaps 10x or 100x?

And, I've been searching for the actual study/paper, but with no success. 'Twould be good for the BU press blurb to link to it...

Found it, I think: https://www.science.org/doi/abs/10.1126/science.aax5440

But, it isn't open-access...

I get an MRI once a year and I frequently fall asleep because nothing puts me to sleep like mechanical white noise. It's kind of a problem because I try to move or jerk awake, which ruins the MRI. My MRIs take forever. I feel terrible for the attendants.
