Somewhat related anecdote: Roughly 20 years ago, I took part in a scientific experiment which aimed to confirm a theory that in blind individuals, parts of the formally vision-related parts of the brain are involved in reading tactile braille. The experiment itself was pretty interesting, since it was conducted in an fMRI machine. Back then, the f in fMRI was sort of the new thing. I was used to a yearly MRI checkup, so this is why I volunteered. It wasnt particularily relaxing, as every session took roughly 3 hours. They tailor-made a helmet from gypsum so that my head wouldnt move at all. My compensation for all of this was clearly not the money (which was too little to remember), but the relaxed chat with the lead brain researcher and the MRI technicians during and after the experiment. At the time, the magnetic field strength of the fMRI I was getting was the highest I ever received. I was used to MRI around 0.5 tesla. During the experiment, I was getting 3 tesla. And I was feeling a strange sort of shiver going down and up my spine. They were experimental imaging people, so I took the opportunity to chat about the fonrtier of healthyness. MRI has this air of "you dont feel it and it cant hurt you". I still believe around 3 tesla can be perceived slightly by your body. I have received higher magnetic field strength in normal medical settings since, and sometimes I can feel that shiver. Anyway, as we were chatting about tesla, the scientist dropped quite casually. "At 11 a mouse is cooking." So much about boundaries. I never asked him if they know because they tried :-)
