In: Current Psychiatry Reports PMID: PMC8576863 DOI: 10.1007/s11920-021-01287-z Abstract: Purpose of review: Binge eating is a transdiagnostic symptom that disproportionately affects females. Sexually dimorphic gonadal hormones (e.g., estradiol, testosterone) substantially impact eating behavior and may contribute to sex differences in binge eating. We examine recent evidence for the role of gonadal hormones in binge eating risk […]

In: Physiology and Behavior PMID: PMC8041470 DOI: 10.1016/j.physbeh.2020.113234 Abstract: The lateral hypothalamic area (LHA) is a heterogeneous brain structure extensively studied for its potent role in regulating energy balance. The anatomical and molecular diversity of the LHA permits the orchestration of responses to energy sensing cues from the brain and periphery. Two of the primary […]

READ MOREIn: Physiology PMID: 31799907 DOI: 10.1152/physiol.00013.2019 Abstract: Ovarian hormones are associated with risk for binge eating in women. Recent animal and human studies suggest that food-related reward processing may be one set of neurobiological factors that contribute to these relationships, but additional studies are needed to confirm and extend findings.

In: Nature Communications PMID: 31664021 DOI: 10.1038/s41467-019-12895-y Abstract: Behavioral impulsivity is common in various psychiatric and metabolic disorders. Here we identify a hypothalamus to telencephalon neural pathway for regulating impulsivity involving communication from melanin-concentrating hormone (MCH)-expressing lateral hypothalamic neurons to the ventral hippocampus subregion (vHP). Results show that both site-specific upregulation (pharmacological or chemogenetic) and […]

In: Physiology & Behavior PMID: 30858100 DOI: 10.1016/j.physbeh.2019.03.005 Abstract: Binge eating is characterized by the consumption of a large amount of palatable food in a short period of time and is a core feature of many eating disorders. Patients with eating disorders are also known to display impairments in inhibitory control, cognition and decision-making, which […]

READ MOREIn: International Journal of Developmental Neuroscience PMID: 28684308 DOI: 10.1016/j.ijdevneu.2017.06.012 Abstract: Ingestive behavior is controlled by multiple distinct peripheral and central physiological mechanisms that ultimately determine whether a particular food should be accepted or avoided. As rodents consume a fluid they display stereotyped rhythmic tongue movements, and by analyzing the temporal distribution of pauses of […]

In: Behavioural Brain Research PMID: 26802728 DOI: 10.1016/j.bbr.2016.01.040 Abstract: The rapid increase in obesity may be partly mediated by an increase in the exposure to cues for food. Food-paired cues play a role in food procurement and intake under conditions of satiety. The mechanism by which this occurs requires characterization, but may involve ghrelin. This […]

In: Physiology & Behavior PMID: 26048303 DOI: 10.1016/j.physbeh.2015.05.037 Abstract: Exposure to environmental cues associated with food can evoke eating behavior in the absence of hunger. This capacity for reward cues to promote feeding behaviors under sated conditions can be examined in the laboratory using cue-potentiated feeding (CPF). The orexigenic neuropeptide Melanin Concentrating Hormone (MCH) is expressed […]

In: Trends in Neurosciences PMID: 23333343 DOI: 10.1016/j.tins.2013.01.002 Abstract: Animals use current, past, and projected future states of the organism and the world in a finely tuned system to control ingestion. They must not only deal effectively with current nutrient deficiencies, but also manage energy resources to meet future needs, all within the constraints of […]
