Research Colloquium
Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

Habits enable animals to efficiently navigate their surroundings while tending to more cognitively demanding environmental factors. One mechanism underlying habit is known as stimulus-response (S-R) learning, which takes place in the dorsolateral striatum (DLS). However, there is limited knowledge regarding the complex striatal microcircuits involved in S-R learning and cognitive flexibility. Recently, attention has turned toward the GABAergic Parvalbumin-expressing (PV) interneurons that can modulate striatal outputs. Here, we utilized chemogenetic techniques and touchscreen cognitive assessments to analyze the influence of PV neurons on S-R learning in mice. When PV neurons were inhibited, during the acquisition of a S-R and cognitive …
