Brain Circuits in Schizophrenia and Smoking

Completed

Conditions studied: Schizophrenia, Schizoaffective Disorder, Schizophreniform Disorder

In brief

The principle aim of the project is to identify the key brain circuits associated with smoking and especially smoking in high risk population. The investigators hope that the study will provide concrete biomarkers for new therapeutic development and ultimately reducing the smoking related health burden.
