Effects Of Development On Hpa Function Following Pubertal Stress, Brittany D. Elliott
Effects Of Development On Hpa Function Following Pubertal Stress, Brittany D. Elliott
Graduate Theses, Dissertations, and Problem Reports
For women, two of the greatest risk factors for affective disorders are adversity experienced during puberty and later becoming pregnant. We have created a translationally relevant mouse model where we address these complex risk factors. Previously, we discovered that pregnant mice (dams) that experienced chronic variable stress (CVS) during puberty display a blunted hypothalamic-pituitary-adrenal (HPA) response when exposed to an acute stressor. Interestingly, this alteration only first becomes apparent during pregnancy, which is a sensitive period for these effects due to normative neuroendocrine changes. Further investigation of the mechanisms underlying this dysfunction revealed altered gene expression in the paraventricular nucleus …
The Short And Long-Term Effects Of Chronic Ketamine During Adolescence On Object Recognition Memory In Rats, William Hardin
The Short And Long-Term Effects Of Chronic Ketamine During Adolescence On Object Recognition Memory In Rats, William Hardin
Seton Hall University Dissertations and Theses (ETDs)
Prior research has demonstrated that ketamine causes deficits in object recognition and location memory following both acute and chronic administration (Pitsikas & Boultadakis, 2009; Venãncio et al., 2011). Although it is well established that abuse of many different kinds of drugs during the critical developmental period of adolescence can lead to impairments in cognition later in adulthood (Gilpin et al., 2012; Wagner et al., 2010), no research has investigated the effects of chronic ketamine administration during adolescence and its effects on behavior in adulthood. With recent research establishing that chronic ketamine during adolescence produces late-onset alterations in electrophysiology during adulthood …
