Our research is interested in the neural
cellular and molecular substrates of inter-individual vulnerability to develop impulsive / compulsive disorders such as drug addiction or Obsessive - compulsive disorder. Our working hypothesis is that impulses
originating from the amygdalo insular networks can drive the behavior through explicit knowledge involving prefrontal and orbitofrontal loops or implicit mechanisms that instead depend upon the functional relationships of these structures with several domains of the striatum. We suggest that inter-individual vulnerability to develop impulsive / compulsive neuropsychiatric disorders stem from aberrant plasticity processes within the corticostriatal networks governing the translation of impulses into actions that ultimately result in a so-called abnormal incentive habit process. Our research is designed according to a vertical
top-down strategy with direct translational perspectives. It stems from a unique combination of contemporary techniques ranging from experimental psychology to causal manipulations of the brain with selective pharmacological tools
DREADDS or optogenetics and
correlational analyses of the brain using state of the art molecular biology and electrophysiology techniques. Our program is subdivided in several converging lines of research: 1. The role of the insular cortex
and its interactions with the BLA and the ventral striatum
in drug addiction and OCD. 2. The nature of the functional interactions between the amygdala and the striatum subserving the establishment of compulsive incentive habits. 3. The cellular and molecular substrates of intrastriatal shifts subserving incentive habits habits. 4. The influence of the environment on inter-individual differences in the vulnerability to develop impulsive / compulsive disorders. Techniques and approaches: 1.

funded by an industrial contract with Shionogi
is based in the CLiC (Cambridge Laboratory for research on impulsive and compulsive disorders) directed by Professor David Belin at the Department of Psychology of the University of Cambridge. The successful candidate will join a highly active research group in which they will take part in a programme of research that aims to establish the therapeutic potential (and underlying mechanism of action) of two new small molecules for the treatment of drug (heroin
cocaine
alcohol) use disorder. The successful applicant will work alongside a post-doctoral researcher and a PhD student with whom they will carry out longitudinal studies using innovative behavioural procedures combined with pharmacology
molecular biology and circuit neuroscience techniques. The successful applicant will ideally have a special interest in the neural mechanisms of addiction and prior experience in Behavioural Pharmacology. The successful applicant will join a highly dynamic and interactive group (comprising three postdoctoral fellows
three PhD students
and a lab manager) passionate about the psychological and neural basis of vulnerability to develop compulsive disorders. At the CLiC
the successful candidate will have many opportunities to acquire a large array of Behavioural Neuroscience techniques and develop a rich culture in Behavioural Pharmacology and Behavioural Neuroscience in an inclusive and supportive environment.
