It’s also consistent with earlier findings for each food and cocaine cues (Yager and Robinson, 203). We conclude that GTs did not method the remifentanil cue since it was not attributed with enough incentive salience to attract animals into close proximity with it, despite the fact that they did discover the CSNeuropsychopharmacologyUS association (they obtain a conditioned orienting response). As a result, variation within the propensity to attribute incentive salience to reward cues is observed employing food cues and cues associated with drugs from a minimum of two various classes, suggesting that this represents a fundamental trait (for instance, Meyer et al, 202).Person Variation inside the Effects of an Opioid Cue LM Yager et alDopamine and Pavlovian Conditioned ApproachIt is properly established that the major rewarding effects of psychomotor stimulant drugs are mediated by dopamine neurotransmission inside the nucleus accumbens (NAc; Di Chiara and Imperato, 988; Lyness et al, 979; Roberts et al, 980; Smart and Bozarth, 987), but this might not be the case for opioids (for review see Badiani et al (20). For instance, systemic blockade of dopamine receptors and either selective lesions of dopamine terminals or blockade of dopamine D receptors within the NAc decreases cocaine selfadministration but has small to no impact on heroin selfadministration (Ettenberg et al, 982; Gerrits et al, 994; Maldonado et al, 993; Pettit et PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23637907 al, 984). Despite the fact that the major reinforcing effects of opioids may not be dopaminedependent, dopamine does appear to become required for cues associated with opioids to acquire secondary (conditioned) reinforcing effects. By way of example, systemic injection of dopamine receptor antagonists or injection of a dopamine D receptor antagonist into the NAc core attenuated the reinstatement of heroin looking for by heroinassociated cues (Bossert et al, 2007; Lai et al, 203), indicating that the ability of an opioid cue to serve as a conditioned reinforcer calls for dopamine. Here we show that dopamine inside the NAc core can also be needed for any remifentanil cue to elicit a signtracking CR, which is believed to reflect the extent to which the cue is attributed with incentive salience (Flagel et al, 20b; Saunders and Robinson, 202). Importantly, although LY300046 flupenthixol dosedependently decreased conditioned approach behavior, it had no effect on conditioned orienting, as reported previously when food was employed as the US (Saunders and Robinson, 202). This suggests that the decrement in strategy be.
