Effects of combined use of alcohol and delta-9-tetrahydrocannibinol on working memory in Long Evans rats.

The increase in social acceptance and legalization of cannabis over the last several years is likely to increase the prevalence of its co-use with alcohol. In spite of this, the potential for effects unique to co-use of these drugs, especially in moderate doses, has been studied relatively infrequently. We addressed this in the current study using a laboratory rat model of voluntary drug intake.

Wheel running leads to sex-specific effects on Western diet-associated glucose homeostasis and brain insulin signaling without altering food-related impulsive choice.

Objectives: There is a clear association between obesity and impulsivity. While exercise can suppress weight gain and decrease impulsive choice (IC), the relationship between impulsivity, the consumption of palatable, energy dense diets, and exercise is unclear. We examined IC before and after Western diet (WD) exposure in rats of both sexes and whether exercise would rescue any diet-mediated increases in IC.
