Parallels and Overlap: The Integration of Homeostatic Signals by Mesolimbic Dopamine Neurons [PDF]
Frontiers in Psychiatry, 2018 Motivated behaviors are often initiated in response to perturbations of homeostasis. Indeed, animals and humans have fundamental drives to procure (appetitive behaviors) and eventually ingest (consummatory behaviors) substances based on deficits in body ...

Cannabis and the Mesolimbic System
, 2016 Cannabis sativa (hemp) is a flowering annual plant whose phytochemical by-products, hashish and marihuana, are the most widely produced and most frequently used illicit drugs in Europe. ?9-Tetrahydrocannabinol is the primary psychoactive constituent, responsible, in a dose-related manner, for euphoria, cognitive effects, and psychotic symptoms, as well

Brain Stimulation, 2020 Background: The fimbria/fornix fiber system is an essential part of the hippocampal-VTA loop, and therefore activities that are propagated through this fiber system control the activity of the mesolimbic dopamine system.

Altered Mesolimbic Dopamine System in THC Dependence [PDF]
Current Neuropharmacology, 2011 To explore the functional consequences of cannabinoid withdrawal in the rat mesolimbic dopamine system, we investigated the anatomical morphology of the mesencephalic, presumed dopaminergic, neurons and their main post-synaptic target in the Nucleus Accumbens.

Mesolimbic dopamine ramps reflect environmental timescales [PDF]
eLifeMesolimbic dopamine activity occasionally exhibits ramping dynamics, reigniting debate on theories of dopamine signaling. This debate is ongoing partly because the experimental conditions under which dopamine ramps emerge remain poorly understood.

Anticipating social feedback involves basal forebrain and mesolimbic functional connectivity
NeuroImage, 2023 The mesolimbic system and basal forebrain (BF) are implicated in processing rewards and punishment, but their interplay and functional properties of subregions with respect to future social outcomes remain unclear.

Stress, depression and the mesolimbic dopamine system
Psychopharmacology, 1996 The present review was aimed at re-evaluating results obtained from animal models of depression based on experimental stressors in the light of the most recent data on the effects of stress on mesolimbic dopamine (DA) functioning. The data reviewed reveal that the effects of stressful experiences on behaviour and on mesoaccumbens DA functioning can be ...

Latency to Reward Predicts Social Dominance in Rats: A Causal Role for the Dopaminergic Mesolimbic System [PDF]
Frontiers in Behavioral Neuroscience, 2019 Reward signals encoded in the mesolimbic dopaminergic system guide approach/seeking behaviors to all varieties of life-supporting stimuli (rewards). Differences in dopamine (DA) levels have been found between dominant and submissive animals.

Comparative Neuroanatomy of the Mesolimbic Dopamine System in Monogamous and Promiscuous Vole Species [PDF]
, 2021 High quality bonds between married couples are salient correlates of health. Humans form monogamous pair bonds with their partner, however, most mammalian species do not. The neurobiological basis of this behavioral difference is unclear.

Nucleus Accumbens and Ventral Tegmental Area Functional Connectivity as a Marker of Reward Sensitivity in Infancy. [PDF]
Dev SciABSTRACT Early functional connectivity within the brain's reward circuitry may provide insight into the developmental origins of individual differences in pleasure and motivation. This study examined resting‐state functional connectivity between two key reward‐related regions, the nucleus accumbens (NAc) and ventral tegmental area (VTA), in 94 one ...
