To investigate the neurobiological basis of individual vulnerability to drug addiction and associated behavioural traits.
Dr Bianca Jupp
Affecting over 39 million people worldwide, drug addiction represents one of the leading causes of preventable death and disease in the developed world. Curiously, despite the prevalence of drug use within society only a relatively small proportion of users go on to develop addiction. The biological mechanisms underlying this differential vulnerability however, remain largely unknown. Importantly these mechanisms may represent potential targets for the development of therapeutics to treat, or indeed, prevent this chronic disease.
To investigate this, our work aims to elucidate the molecular and neural substrates of various behavioural traits co-expressed in individuals at risk for addiction, such as impulsivity, and determine how these in turn contribute to the emergence of addictive behaviour. This work predominantly utilises neuroimaging approaches (MRI and PET) combined with the more conventional molecular and pharmacological techniques in rodent models.
