Behavioural neuropharmacology


Research summary

The main research line in the laboratory of Behavioural Neuropharmacology concerns the study of the neurobiological mechanisms underlying drug addiction (mostly cannabinoids and nicotine) in rodents (mice and rats) and, more in general, of compulsive and addictive behaviours (e.g. binge eating) (Fig. 1).

We routinely use animal models of drug addiction and dependence and perform behavioral test to understand how drugs of abuse, including the most recent novel psychoactive substances (NPS), may impact on brain functioning and alter emotional states and behavioral responses. All phases of the drug addiction cycles are investigated, from the initial occasional use to relapse after drug abstinence

Our research includes the study of the potential risk factors that may enhance vulnerability to addiction, like age and animal strains but also levels of steroid hormones and psychiatric comorbidity (depression). Particular attention is given to sex-dependent differences in cannabinoid abuse and dependence (Fig. 3).
