abstract：:Caffeine is a widely self-administered psychostimulant with purported neuroprotective and procognitive effects in rodent models of aging. The cholinergic basal forebrain is important for arousal and attention and is implicated in age-related cognitive decline. Accordingly, we determined the effects of caffeine on chol...
