The following review summarizes and examines Mark Solms's article Dreaming
and REM Sleep are controlled by different brain mechanisms, which argues wh
y the understanding of REM sleep as the physiological equivalent of dreamin
g needs to be re-analyzed. An analysis of Solms's article demonstrates that
he makes a convincing argument against the paradigmatic activation-synthes
is model proposed by Hobson and McCarley, and provides provocative evidence
to support his claim that REM and dreaming are dissociable states. In addi
tion, to situate Solms's findings in concurrent research, other studies are
mentioned that are further elucidated by his argument.
