The Role of Mu Opioid Receptors in High Fat Diet-Induced Reward and Potentiation of the Rewarding Effect of Oxycodone by Asif Iqbal, Abdul Hamid, Syed Muzzammil Ahmad, Kabirullah Lutfy

“…The place conditioning paradigm was used as an animal model of reward to determine if short-time (STC, 2 h) or long-time (LTC, 16 h) conditioning with HFD induces reward or alters the rewarding action of oxycodone. …”

Shift of circadian feeding pattern by high-fat diets is coincident with reward deficits in obese mice. by Lidia Morales, Nuria Del Olmo, Ismael Valladolid-Acebes, Alberto Fole, Victoria Cano, Beatriz Merino, Paula Stucchi, Daniela Ruggieri, Laura López, Luis Fernando Alguacil, Mariano Ruiz-Gayo

“…We demonstrate that i) ad libitum HF diet attenuates cocaine and food reward in the CPP protocol, and ii) forced synchronization of feeding prevents this reward deficit. …”

Calorie information and dieting status modulate reward and control activation during the evaluation of food images. by Andrea L Courtney, Emma K PeConga, Dylan D Wagner, Kristina M Rapuano

“…Finally, whole brain multivariate pattern analysis (MVPA) revealed patterns of activation in a region of the reward system-the orbitofrontal cortex (OFC)-that were more similar for food images presented with and without calorie information in dieting than non-dieting participants, suggesting that dieters may spontaneously consider calorie information when viewing food. …”
