*OUCH* Lior:
Empirically, the brainwave-frequency required to have any chance
of emulating REM is *gamma* [13+].
Theta [4-8] is the frequency of Type II/III sleep. These are not essential
types, as defined by which ones the brain tries to catch up on. [They
are useful when doing calculations both accurately and quickly....]
The criticals are Type IV and REM.
