Activity of orally self-administered acetaldehyde in an operant/conflict paradigm in rats; involvement of cannabinoid cb1 receptors

2012

Acetaldehyde (ACD), ethanol first metabolite, interacts with the dopaminergic reward system, and with the neuropeptidergic transmission in the hypothalamus. Self-administration within operant conditioning is a valid model to investigate drug-seeking and drug-taking behaviour in rats. Cannabinoid CB1 receptors are involved in reinstatement of alcohol-seeking behaviour and of many other drugs of abuse (3). Accordingly, this study was aimed at the evaluation of: 1) the motivational properties of oral ACD in the induction and maintenance of an operant-drinking behaviour; 2) the onset of a relapse drinking behaviour, following ACD deprivation; 3) ACD effect in a conflict situation employing the …
