Neural and psychological mechanisms underlying compulsive drug seeking habits and drug memories – indications for novel treatments of addiction

European Journal of Neuroscience, Journal Year: 2014, Volume and Issue: 40(1), P. 2163 - 2182

Abstract This review discusses the evidence for hypothesis that development of drug addiction can be understood in terms interactions between Pavlovian and instrumental learning memory mechanisms brain underlie seeking taking drugs. It is argued these behaviours initially are goal‐directed, but increasingly become elicited as stimulus–response habits by drug‐associated conditioned stimuli established conditioning. further compulsive use emerges result a loss prefrontal cortical inhibitory control over habits. Data reviewed indicate transitions from to abuse depend upon shifts ventral dorsal striatal behaviour, mediated part serial connectivity striatum midbrain dopamine systems. Only some individuals lose their use, importance behavioural impulsivity vulnerability trait predicting stimulant animals humans, together with consideration an emerging neuroendophenotype discussed. Finally, potential developing treatments considered light neuropsychological advances reviewed, including possibility targeting reconsolidation extinction reduce influences on means promoting abstinence preventing relapse.

Inhibition of ERK pathway or protein synthesis during reexposure to drugs of abuse erases previously learned place preference

Repeated association of drugs abuse with context leads to long-lasting behavioral responses that reflect reward-controlled learning and participate in the establishment addiction. Reactivation consolidated memories is known produce a reconsolidation process during which undergo labile state. We investigated whether reexposure had similar effects. Cocaine administration activates extracellular signal-regulated kinase (ERK) striatum, ERK activation required for acquisition cocaine-induced conditioned place preference (CPP). When mice previously cocaine-place were reexposed cocaine drug-paired compartment after systemic SL327, an inhibitor activation, CPP response was abolished 24 h later. This procedure also phosphorylation glutamate receptor-1 observed ventral dorsal later, test. Erasure by SL327 combination did not result from enhanced extinction. Similarly, morphine presence long-lastingly learned morphine-CPP. The effects on cocaine- or morphine-CPP reproduced protein synthesis inhibition. In contrast, inhibition alter acquired locomotor sensitization cocaine. Our findings show established can be disrupted when reactivation associates both drug administration. involves ERK, treatment preventing erases response. These results suggest potential therapeutic strategies explore

Cue-Induced Cocaine Seeking and Relapse Are Reduced by Disruption of Drug Memory Reconsolidation

Journal of Neuroscience, Journal Year: 2006, Volume and Issue: 26(22), P. 5881 - 5887

Published: May 31, 2006

Long-lasting vulnerability to drug cue-induced relapse a drug-taking habit is major challenge the treatment of addiction. Here we show that blockade memory reconsolidation, through infusion Zif268 antisense oligodeoxynucleotides into basolateral amygdala shortly before reexposure cocaine-associated stimulus but not simply training context, severely impaired subsequently cue-maintained cocaine seeking under second-order schedule reinforcement and abolished reinstatement seeking. This reduction in after disrupted reconsolidation was only seen several hundred pairings with self-administered cocaine, older, as well recent, memories were also disrupted. Reconsolidation may thus provide potential therapeutic strategy for prevention
