When people transition from an alert state to a sleeping state, their brain waves begin to slow down, but bursts of rapid, rhythmic brain waves are also produced. what are these small bursts of activity called when they occur in stage 2 (nrem-2) sleep?

It was the electroencephalograph (EEG) development that enabled researchers to study rest in manners that were not already conceivable.

Explanation:

You've most likely heard that you progress through a progression of stages as you rest, however what precisely does that mean? Rest is rest, isn't that so?

As a general rule, there is still a great deal going on inside your head while you're in sleep, and it is the action in your cerebrum that denotes these diverse rest stages.
