Chemical compounds that target dopamine (DA) D1 or D3 receptors have shown promise as potential interventions in animal models of cue-induced relapse. However, undesirable side effects or pharmacodynamic profiles have limited the advancement of new compounds in preclinical studies when administered as independent treatments. In this series of experiments, we explored the effects of co-administration of a D1-recepter partial agonist (SKF 77434) and a D3-receptor antagonist (NGB 2904) in heroin-seeking rats within a ‘conflict’ model of abstinence and cue-induced relapse. Rats were first trained to press a lever to self-administer heroin and drug delivery was paired contingently with cues (e.g., …

Maternal caregiving is a dynamic process that requires extensive cognitive, motivational, and affective processing. World-wide, approximately 17% of mothers are diagnosed with postpartum depression yearly (Wang et al., 2021). Untreated, mothers with postpartum depression experience deficits in cognition, motivation, affect, and parenting (Arteche et al., 2011; Dix and Meunier, 2009; Lovejoy et al., 2000). Although postpartum depression is related to compromised parenting, to date, few studies have examined the neurobiological mechanisms by which maternal behavior is compromised in postpartum depression (Field, 2010; Murray et al., 1996). This dissertation aims to examine how depression neurobiologically disrupts parenting abilities. These studies …
