The Two-Hour Marathon: What's The Equivalent For Women?, Sandra K. Hunter, Michael J. Joyner, Andrew M. Jones

Exercise Science Faculty Research and Publications

The principal characteristic of the runner who may break the two-hour barrier in the marathon will be their sex: the person will be male. The fastest men outperform the fastest women because of sex differences in physiology including a higher VȮ2 max. This viewpoint addresses the questions of what is the two-hour equivalent for women, and who will break this barrier? The current sex difference in the world record for the marathon is ~10% which is slightly less than the mean sex difference in performance usually documented between elite men and women distance runners. Based on comparisons of the top …

Drug Predictive Cues Activate Aversion-Sensitive Striatal Neurons That Encode Drug Seeking, Daniel S. Wheeler, Mykel A. Robble, Emily M. Hebron, Matthew J. Dupont, Amanda L. Ebben, Robert A. Wheeler

Biomedical Sciences Faculty Research and Publications

Drug-associated cues have profound effects on an addict’s emotional state and drug-seeking behavior. Although this influence must involve the motivational neural system that initiates and encodes the drug-seeking act, surprisingly little is known about the nature of such physiological events and their motivational consequences. Three experiments investigated the effect of a cocaine-predictive stimulus on dopamine signaling, neuronal activity, and reinstatement of cocaine seeking. In all experiments, rats were divided into two groups (paired and unpaired), and trained to self-administer cocaine in the presence of a tone that signaled the immediate availability of the drug. For rats in the paired group, …
