Ghrelin, Cannabinoids, and Motivation: Increased Food Motivation on Progressive Ratio Paradigm Through MAGL/FAAH Inhibition in a Rat Model
Both ghrelin and endogenous cannabinoids act in the ventral tegmental area (VTA) to increase feeding behaviours, through their interaction is not understood. It is hypothesized that ghrelin influences this system by stimulating the release of endocannabinoids from dopamine cells through its …

Baseline cortical activation to food pictures associated with change in weight, hunger, cognitive restraint, and disinhibition following bariatric surgery
… functional magnetic resonance imaging (fMRI) food motivation paradigms may reveal particular patterns of brain activation, which could indicate successful outcomes in weight and other behavioral outcomes following bariatric surgery. The aim of the present study was to determine if activation …

Neurobehavioral Mechanisms Contributing To Alterations In Food Intake Driven By Caudal Hindbrain Acting Signals
… treatment. Given that energy balance and food intake are regulated in the central nervous system, the development of treatment relies on basic science investigations of the neuroendocrine controls of feeding and the neural hubs that modulate this control, including the nucleus tractus …

The impact of a protein-rich breakfast on food cravings and reward in overweight/obese 'breakfast skipping' adolescent girls
… to beneficial changes in perceived appetite, food cravings, and plasma homovanillic acid (HVA), which is an index of central dopamine production, in overweight/obese 'breakfast skipping' (BS) teen girls. A randomized crossover design was incorporated in which 20 BS girls (age 19[plus or …

Neuromedin U Acts via the Paraventricular Nucleus of the Hypothalamus and the Dorsal Raphe Nucleus to Regulate Motivation for High-Fat Food
Motivation for high-fat food is thought to contribute to excess caloric intake in obese individuals. A novel regulator of motivation for food may be neuromedin U (NMU), a highly-conserved neuropeptide that influences food intake. Although these effects of NMU have primarily been attributed to …

Gluten-free diet adherence in adult coeliac disease: Exploring multiple perspectives
… thematic clusters: The high cost of gluten-free food was perceived to be the most important factor. Healthcare professionals perceived the availability of gluten-free sandwiches to be significantly less important than people with 3 coeliac disease and household members. Other factors included: …

Identification and Delineation of Neuronal Pathways Underlying Hypophagia
… neurons had no impact on <em>ad libitum</em> food intake and survival, which overturned the dogma that adult deletion of these neurons led to lethal phenotype. Interestingly, I did observe that these neurons are required for fasting-induced refeeding. This finding supports the "thrive gene" …

Understanding the Genetic Basis of Obesity: Lessons from Man’s Best Friend
… factors were mediated through an increase in food motivation, providing valuable insight into underlying mechanisms of action in canine obesity. Subsequently, a genome wide association study (GWAS) for obesity in Labrador retrievers was conducted. Multiple obesity-associated loci were …

From genomics to function: Canine genetics highlight novel mechanisms of obesity and related traits
… a genome wide association study (GWAS) for food motivation was performed in a large cohort of mixed ancestry dogs. Although no genome wide significant associations were identified, the nominally significant loci were narrow and six were prioritised. Relevant candidate genes were identified …

Effects of Ventromedial Hypothalamic Lesions on Food-Reinforced Fixed Ratio Responding
… hyperphagia. This striking effect on ad libitum food intake is sometimes accompanied by an increase and sometimes by a decrease in other measures of propensity to eat such as food-rewarded lever pressing. The current experiments attempt to discover the conditions under which these opposite …

Strategies to Identify Therapeutic Opportunities in the Treatment of Addictive Disorders
… demonstrates an association between high fat food binge intake and cue reactivity, both of which are modulated by insula activity. Further, the clinically-approved serotonin (5-HT) 5-HT2A receptor (5-HT2AR) antagonist/inverse agonist pimavanserin and 5-HT2CR agonist lorcaserin used alone or in …
