Whereas painful stimuli cause potentiation or sensitization, meaning the pain gets worse as it goes on
We're going to uncover what sleep is and explore the stages of sleep and the corresponding electrical activity in the brain. We will then dive into the intricacies of the neurobiology of sleep, what sleep does, what sleep deprivation leads to, and finally, what you can do to improve your sleep.
