4. Medically and psychiatrically stable (in the opinion of the investigator) and no significant relapse of schizophrenia (i.e. requiring hospitalisation) for the 2 months before admission

Additional exclusion criteria for PET and MRI only:
1. Exposure to radiation, such that in combination with this trial, exposure would be more than 10 mSv within the previous 12 months (PET exclusion only)
2. Presence of a cardiac pacemaker or other implanted electronic device
3. Contradictions to having an MRI scan, such as (but not limited to) ferromagn
