Abstract

Brain-derived neurotrophic factor (BDNF) has been implicated in cognition and the effects of chronic stress. We have previously shown in mice that chronic adolescent treatment with corticosterone (CORT), to simulate stress, resulted in spatial memory deficits and markedly elevated levels of the N-methyl-D-aspartate (NMDA) receptor subunit NR2B in adult male BDNF heterozygous mice (BDNF+/-), but not in wildtype controls (WT) or females. The aim of the present study was to further characterize this 'two hit' model, including whether these effects are long-lasting. CORT treatment was delivered in the drinking water from 6 to 9 weeks of age. As previously demonstrated, male BDNF+/- mice treated ..
