Addicts Lose Plasticity What are the biological mechanisms associated with the transition from occasional drug use to addiction? In rats, like in humans, even after a prolonged period of drug intake, only a limited number of animals develop addiction-like behavior despite the amount of drug taken by all subjects being the same. Kasanetz et al. (p. 1709) compared the expression of N-methyl-d-aspartate (NMDA)–dependent long-term depression (NMDA-LTD) in the nucleus accumbens of addicted and… 

Prefrontal synaptic markers of cocaine addiction-like behavior in rats

Specific synaptic impairments in the prelimbic PFC (pPFC) circuits associated with addiction are identified and support the idea that alterations of synaptic plasticity are core markers of drug dependence.

The synaptic pathology of drug addiction.

This chapter discusses the current understanding of drug-induced neuroplasticity within the mesocorticolimbic brain system that contributes to the development of addiction and the persistence of relapse to drug seeking.

Neural Circuit Plasticity in Addiction

Biological substrates of addiction.

This review is an introduction to addiction, the reward circuitry, and laboratory addiction models and shows how altered function of a wide variety of brain regions is tightly associated with specific manifestations of drug abuse.

Addiction-like Synaptic Impairments in Diet-Induced Obesity

Rapid, transient synaptic plasticity in addiction

New medications for drug addiction hiding in glutamatergic neuroplasticity

It is argued for a concerted effort to clinically evaluate the hypothesis that targeting glial and neuronal proteins regulating excitatory synaptic plasticity may prove beneficial in treating addiction.

Neuroplasticity in addiction: cellular and transcriptional perspectives

A summary of more recent research that has furthered understanding of drug-induced neuroplastic changes both at the level of the synapse, and on a transcriptional level, and how these changes may relate to the human disease of addiction is provided.

Aberrant learning and memory in addiction

Understanding Addiction Using Animal Models

The most common preclinical models of addictive behavior, including non-contingent models in which animals are passively exposed to rewarding substances, as well as widely used contingent models such as drug self-administration and relapse are reviewed.



Neural mechanisms underlying the vulnerability to develop compulsive drug-seeking habits and addiction

Evidence showing that impulsivity, a spontaneously occurring behavioural tendency in outbred rats that is associated with low dopamine D2/3 receptors in the nucleus accumbens, predicts both the propensity to escalate cocaine intake and the switch to compulsive drug seeking and addiction is summarized.

Synaptic plasticity and addiction

Accumulated evidence that drugs of abuse can hijack synaptic plasticity mechanisms in key brain circuits, most importantly in the mesolimbic dopamine system, which is central to reward processing in the brain is presented.

N-Acetylcysteine Reverses Cocaine Induced Metaplasticity

It is shown that cocaine self-administration induces metaplasticity that inhibits further induction of synaptic plasticity, and this impairment can be reversed by NAC, a drug that also prevents relapse.

Evidence for Addiction-like Behavior in the Rat

It is reported that behaviors that resemble three of the essential diagnostic criteria for addiction appear over time in rats trained to self-administer cocaine.

Cocaine-evoked synaptic plasticity: persistence in the VTA triggers adaptations in the NAc

Overriding mGluR1 in vivo led to synaptic plasticity in the NAc, which contributes to cocaine-seeking behavior after protracted withdrawal and could represent a first step in the recruitment of the neuronal network that underlies drug addiction.

Neuroplasticity in the mesolimbic dopamine system and cocaine addiction

Results are reviewed on the effect of cocaine exposure on selected signalling cascades, growth factors and physiological processes previously implicated in neuroplasticity underlying normal learning and memory, and how these factors may interact to initiate and sustain cocaine psychomotor sensitization and cocaine seeking.

Neural mechanisms of addiction: the role of reward-related learning and memory.

Progress in identifying candidate mechanisms of addiction is reviewed, including molecular and cellular mechanisms that underlie long-term associative memories in several forebrain circuits (involving the ventral and dorsal striatum and prefrontal cortex) that receive input from midbrain dopamine neurons.

REVIEW: Behavioural assessment of drug reinforcement and addictive features in rodents: an overview

This review provides an extensive overview and a critical evaluation of the methods currently used for studying drug‐induced reinforcement as well as specific features of addictive behaviour, and various procedures have been proposed as possible rodent analogues of addiction’s major elements.
