Cocaine-induced increases in motivation require 2-arachidonoylglycerol mobilization and CB1 receptor activation in the ventral tegmental area.

Neuropharmacology 2021 Aug 28;193:108625. Epub 2021 May 28.

Dept. of Anatomy and Neurobiology, University of Maryland School of Medicine, Baltimore, MD, USA. Electronic address:

A wide body of evidence supports an integral role for mesolimbic dopamine (DA) in motivated behavior. In brief, drugs that increase DA in mesolimbic terminal regions, like cocaine, enhance motivation, while drugs that decrease DA concentration reduce motivation. Data from our laboratory and others shows that phasic activation of mesolimbic DA requires signaling at cannabinoid type-1 (CB1) receptors in the ventral tegmental area (VTA), and systemic delivery of CB1 receptor antagonists reduces DA cell activity and attenuates motivated behaviors.

Hypocretin/Orexin Receptor Pharmacology and Sleep Phases.

Front Neurol Neurosci 2021 28;45:22-37. Epub 2021 May 28.

Center for Neuroscience, Biosciences Division, SRI International, Menlo Park, California, USA.

The hypocretins/orexins are two excitatory neuropeptides, alternately called HCRT1 or orexin-A and HCRT2 or orexin-B, that are the endogenous ligands for two G-protein-coupled receptors, HCRTR1/OX1R and HCRTR2/OX2R. Shortly after the discovery of this system, degeneration of hypocretin/orexin-producing neurons was implicated in the etiology of the sleep disorder narcolepsy. The involvement of this system in a disorder characterized by the loss of control over arousal state boundaries also suggested its role as a critical component of endogenous sleep-wake regulatory circuitry.

Incentive motivation: 'wanting' roles of central amygdala circuitry.

Behav Brain Res 2021 May 20;411:113376. Epub 2021 May 20.

Department of Psychology, University of Michigan, Ann Arbor, MI, USA.

The central nucleus of amygdala (CeA) mediates positively-valenced reward motivation as well as negatively-valenced fear. Optogenetic or neurochemical stimulation of CeA circuitry can generate intense incentive motivation to pursue and consume a paired natural food, sex, or addictive drug reward, and even create maladaptive 'wanting what hurts' such as attraction to a shock rod. Evidence indicates CeA stimulations selectively amplify incentive motivation ('wanting') but not hedonic impact ('liking') of the same reward. Read More

The diverse effects of brain glucagon-like peptide 1 receptors on ingestive behaviour.

Authors:
Diana L Williams

Br J Pharmacol 2021 May 14. Epub 2021 May 14.

Department of Psychology, Program in Neuroscience, Florida State University, Tallahassee, Florida, USA.

Glucagon-like peptide 1 (GLP-1) is well known as a gut hormone and also acts as a neuropeptide, produced in a discrete population of caudal brainstem neurons that project widely throughout the brain. GLP-1 receptors are expressed in many brain areas of relevance to energy balance, and stimulation of these receptors at many of these sites potently suppresses food intake. This review surveys the current evidence for effects mediated by GLP-1 receptors on feeding behaviour at a wide array of brain sites and discusses behavioural and neurophysiological mechanisms for the effects identified thus far.

The use of ICT devices as part of the solo eating experience.

Appetite 2021 Oct 11;165:105297. Epub 2021 May 11.

Department of Human Centered Design, Delft University of Technology, Landbergstraat 15, 2628 CE Delft, the Netherlands.

An increasing number of people tend to eat alone due to social changes and an altered attitude towards cooking and eating practices. Anecdotal reports indicate that solo diners tend to use information and communication technology devices, for example, the smartphone, as part of the eating experience. While lab studies suggest that the devices contribute to an increased high-calorie food intake and decreased feeling of satiety, these studies disregard the everyday experience and motivation of solo diners.
