Endocannabinoid system nucleus accumbens

Pharmacological Enhancement Of The Endocannabinoid System In The Abstract Background and purpose: Evidence indicates that the endocannabinoid, 2-arachidonoylglycerol (2-AG), increases food intake when injected into the nucleus accumbens shell (NAcS), thereby potentially activating hypothalamic nuclei involved in food intake regulation. We aimed to Endocannabinoid System Components: Overview and Tissue The distribution and function of the components of the endocannabinoid system (ECS) in the central nervous system (CNS) and immune processes have garnished significant research focus with major milestones.

Cannabinoids inhibit excitatory inputs to neurons in the shell of The nucleus accumbens (NAc) represents a critical site for the rewarding properties of diverse classes of drugs of abuse. Glutamatergic afferents to the NAc are involved in the actions of psychostimulants and opioids, while the potentiation of dopaminergic neurotransmission in the NAc is a common feature of abused drugs, including cannabinoids. The endocannabinoid system regulates synaptic transmission in The endocannabinoid (eCB) system is involved in pathways that regulate drug addiction and eCB‐mediated synaptic plasticity has been linked with addictive behaviours. Here, we investigated the molecular mechanisms underlying the changes in eCB‐dependent synaptic plasticity in the nucleus accumbens core (NAcc) following short‐term withdrawal from repeated morphine treatment.

It is thought to play an important role in reward, pleasure, laughter, addiction, aggression Addiction | GH Medical Following the same line, morphine withdrawal increased DAGLα expression in rat nucleus accumbens and increased depolarization-induced suppression of inhibition, suggesting that 2-AG mediates this process (Wang et al., 2016). Furthermore, a study testing the effects of cocaine in orexin neurons found very similar results (Tung et al., 2016).

Endocannabinoids in Amygdala and Nucleus Accumbens Mediate Social The brain endocannabinoid system plays a crucial role in emotional processes. We have previously identified an important role for endocannabinoids in social play behavior, a highly rewarding form of social interaction in adolescent rats. Here, we tested the hypothesis that endocannabinoid modulation of social play behavior occurs in brain regions implicated in emotion and motivation.
