Resumen

Chronic administration of caffeine (75 mg/kg/day) to rats for 12 days increased [³H]R-PIA binding in the cerebral cortex and cerebellum and [³H]NECA binding to high affinity receptor sites in the striatum. The results indicate that both adenosine A₁ and A₂ receptor subtypes possess mechanisms of adaptation to chronic caffeine treatment. In addition, adenosine A₁ receptor binding shows heterogenous neuroanatomical pattern indicating that the A, response to caffeine treatment presents regional variation in the rat brain.
