Why do we repeat behaviours that we know are bad for us? Or make impulsive poorly considered decisions? These decision making processes are relevant in our daily lives and can be hijacked in disorders of pathology. The Voon lab spans across Cambridge and Shanghai focusing on interventional psychiatry and is anchored on understanding mechanisms underlying human self-control and compulsivity relevant to addictions and compulsive disorders. The lab focuses on identifying modifiable anatomical and functional biomarkers for invasive and non-invasive neuromodulation with the ultimate aim to optimise treatment approaches. We use multiple modalities including imaging, physiology, pharmacological challenges, cognitive neuroscience and computational modelling approaches.
