title: Circadian variation in BDNF mRNA expression in the rat hippocampus.
abstract: BDNF mRNA levels in the hippocampus were studied during the circadian cycle by in situ hybridization. These levels display a circadian pattern, which may be due to regulation by corticosterone. This may have consequences for hippocampal functioning at different time points of the circadian cycle.
