Abstract/OtherAbstract:
Alcohol consumption during pregnancy can result in a myriad of health problems in the affected offspring ranging from growth deficiencies to central nervous system impairments that result in cognitive deficits. Adult hippocampal neurogenesis is thought to play a role in cognition (i.e. learning and memory) and can be modulated by extrinsic factors such as alcohol consumption and physical exercise. We examined the impact of voluntary physical exercise on adult hippocampal neurogenesis in a rat model of fetal alcohol spectrum disorders (FASD). Intragastric intubation was used to deliver ethanol to rats in a highly controlled fashion through all three trimester equivalents (i.e. throughout gestation and during the first 10 days of postnatal life). Ethanol-exposed animals and their pair-fed and ad libitum controls were left undisturbed until they reached a young adult stage at which point they had free access to a running wheel for 12 days. Prenatal and early postnatal ethanol exposure altered cell proliferation in young adult female rats and increased early neuronal maturation without affecting cell survival in the dentate gyrus (DG) of the hippocampus. Voluntary wheel running increased cell proliferation, neuronal maturation and cell survival as well as levels of brain-derived neurotrophic factor in the DG of both ethanol-exposed female rats and their pair-fed and ad libitum controls. These results indicate that the capacity of the brain to respond to exercise is not impaired in this model of FASD, highlighting the potential therapeutic value of physical exercise for this developmental disorder.
