abstract：:Adenosine has been implicated in the regulation of rapid eye movement sleep (REMS). In an attempt to understand the mechanism of production of adenosine in relation to REMS it was hypothesized that should it be involved in REMS, the latter's deprivation is likely to affect its synthetic machinery. Hence, male albino r...
