Cocaine serves as a peripheral interoceptive conditioned stimulus for central glutamate and dopamine release. [PDF]
PLoS ONE, 2008 Intravenous injections of cocaine HCl are habit-forming because, among their many actions, they elevate extracellular dopamine levels in the terminal fields of the mesocorticolimbic dopamine system. This action, thought to be very important for cocaine's

Frontiers in Pharmacology, 2022 Mechanistic target of rapamycin (mTOR) C1 and its downstream effectors have been implicated in synaptic plasticity and memory. Our prior work demonstrated that reactivation of cocaine memory engages a signaling pathway consisting of Akt, glycogen ...

Proteome-informed machine learning studies of cocaine addiction [PDF]
arXiv, 2021 Cocaine addiction accounts for a large portion of substance use disorders and threatens millions of lives worldwide. There is an urgent need to come up with efficient anti-cocaine addiction drugs. Unfortunately, no medications have been approved by the Food and Drug Administration (FDA), despite the extensive effort in the past few decades.

Can ropinirole modulate reinforcing subjective effects of cocaine in humans?
Frontiers in Psychiatry, 2011 In this study we evaluated, by means of the Cocaine Rush Visual Analogue Scale (CRVAS), the impact of ropinirole on the expected rush induced by cocaine in a group of heroin addicts abusing cocaine; the self-reported reaction to the rush blockade (if ...

Initial d2 dopamine receptor sensitivity predicts cocaine sensitivity and reward in rats. [PDF]
PLoS ONE, 2013 The activation of dopamine receptors within the mesolimbic dopamine system is known to be involved in the initiation and maintenance of cocaine use. Expression of the D2 dopamine receptor subtype has been implicated as both a predisposing factor and ...

Frontiers in Behavioral Neuroscience, 2012 Considerable evidence suggests that transmission at hypocretin-1 (orexin-1) receptors (Hcrt-R1) plays an important role in the reinstatement of extinguished cocaine-seeking behaviors in rodents.

Violence in Guatemala pushes adults and children to seek work in Mexico [PDF]
arXiv, 2022 This article estimates the impact of violence on emigration crossings from Guatemala to Mexico as final destination during 2009-2017. To identify causal effects, we use as instruments the variation in deforestation in Guatemala, and the seizing of cocaine in Colombia. We argue that criminal organizations deforest land in Guatemala, fueling violence and

mGluR5 Knockout mice exhibit normal conditioned place-preference to cocaine [PDF]
, 2012 Metabotropic glutamate receptor 5 (mGluR5) null mutant (-/-) mice have been reported to totally lack the rein- forcing or locomotor stimulating effects of cocaine. We tested mGluR5 -/- and +/+ mice for their locomotor and conditioned place- preference response to cocaine.

Cocaine Use Prediction with Tensor-based Machine Learning on Multimodal MRI Connectome Data [PDF]
arXiv, 2023 This paper considers the use of machine learning algorithms for predicting cocaine use based on magnetic resonance imaging (MRI) connectomic data. The study utilized functional MRI (fMRI) and diffusion MRI (dMRI) data collected from 275 individuals, which was then parcellated into 246 regions of interest (ROIs) using the Brainnetome atlas.
