I was wondering if they were specific ways to modify sleep in human or other animals, and more precisely that modify the different phases that compose it. By phase I mean Slow Wave Sleep (SWS) and Rapid Eye Movement (REM).
Is there any technique wich enable us to supress or increase the amount of sleep in the REM phase and/or the amount of sleep in SWS ?
I think for exemple that some antidepressant reduce the amount of REM sleep. Is there any other pharmacological tools that modify the amount of REM sleep and is there some equivalent for the SWS ?
Also, is there some non-pharmacological tools ? I am thinking for exemple at Transcranial magnetic stimulation or intracranial stimulation.
