Variations in arousal levels can impact respiratory patterns. The mechanisms by which breathing behaviors can influence arousal state is not fully understood. In this study, we investigated the role of astrocytes in the preBötzinger complex (preBötC) in modulating arousal states via breathing in adult conscious rats. Using viral vector tools, we selectively interfered with astrocytic signaling in the

Food Selection in a Buffet Scenario by Persons in Recovery from Substance Use Disorder: Testing a Parallel Mediation Model including Impulsivity, Food Craving, and Breadth of Drug Use Physiol. Behav. (IF 2.9) Pub Date : 2024-01-05 Laurence J. Nolan
Elevated food cravings and higher food consumption and body weight have been reported in studies of people in recovery from substance use disorder (SUD). In a previous study, SUD recovery status predicted the energy from selected food images in a virtual buffet meal, most strongly in those with high reward responsiveness. The present study was conducted to determine which psychological variables might

Patterns of ingestion of rats during chronic oral administration of lithium chloride Physiol. Behav. (IF 2.9) Pub Date : 2023-12-30 Denesa R. Lockwood, Jennifer A. Cassell, James C. Smith, Thomas A. Houpt
Chronic lithium administration to rodents is used to explore the potential neural mechanisms of mood stabilization, as well as to model the side effects of chronic lithium on multiple organ systems. Oral administration of lithium in the maintenance diet or drinking water is convenient, but lithium can acutely affect intake and it can mediate acquisition of conditioned taste aversions (CTA). We compared
