uh, here is an extremely interesting history of the prosymographic system , munt glues and maternal,se are neurophysiologists who threw, uh, electrodes on the cat's head and noticed that she had different brain activity in different phases of sleep and began to study on the basis that this is how brain activity was discovered when we say that slow wave and fast wave sleep, yes, that is, it started from uh, neurophysiologists who studied exactly the activity of these very waves, and then already arranged that it would be nice to see how the muscles are relaxed in order to understand some phase of sleep, how the eyeballs move, to understand again. what phase of sleep is the person in? from this actually cruising with an analogy, as a science, as a branch of medicine, it has been studied very little. yes, all new new discoveries appear, they will appear due to the fact that their visualization ability is improving with us. that is, we have a functional mri. yes, we can look at the activity of certain areas of the brain in an awake state. during sleep , neurobiology is studied, genetics
