Mammalian adolescence can be a difficult transition from childhood to adulthood, where increases in impulsivity and novelty- and risk-seeking are combined with heightened affect and elevated sensitivity to stress. Indeed, during adolescence, first drug use patterns emerge and in the continental United States, increasing misuse of amphetamines has been observed in adolescent youth. Myriad neural mechanisms underlie this shift in adolescence, including the dynamic remodeling of the mesocorticolimbic (MCL) pathway. Repeated drug administration affects neuroimmune substrates within the MCL circuit including toll-like receptor 4 (TLR4)Advances in addiction neuroscience indicate that drugs of abuse activate neural TLR4 and implicate glial TLR4 …

Term neonates with hypoxic-ischemic (HI) injury are at risk for devastating neurological sequelae. The objective of this study is to determine if altering the early environment for maternal care-taking impacts the immediate and long-term sequelae of HI offspring. The Rice-Vannucci model was used to induce HI in postnatal day (PND) 7 Long-Evans pups. Litters were assigned to a closed nest (CN) or normal standard housing (SH) condition. Neurobehavioral development, cognitive ability, and stress response were assessed to establish any benefits of the CN condition. Finally, postmortem brain tissue was analyzed for morphometric markers of injury.
