"Sharp wave ripples are intense, compressed oscillations that occur in the hippocampus when the hippocampus is working off-line, most often during stage four sleep, which, along with stage three, is the deepest level of sleep."
I'm not an expert on the subject, but how can two stages both be the "deepest"?
- Leon 17y agoBoth stages have delta waves in the same range but induce different effects on the brain. They're both characterized by the same measure for depth (of sleep).
