Summary

The aim of this project is to investigate:

* The status of the central serotonin (5-hydroxytryptamine, 5-HT) system in compulsive behaviour and how it is affected by sub-chronic escitalopram administration
* The mechanisms underlying how sub-chronic administration of escitalopram affects the central 5-HT system
* How changes in cognitive performance, including the balance between habitual and goal-directed mechanisms, are affected in compulsive behaviour by boosting 5-HT function
* How functional brain changes in cognitive function measured with magnetic resonance imaging relate to altered 5-HT function following escitalopram administration.
