Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goals of this study is to determine (1) if differences in D2/3 receptor affinity states exist between medication-free subjects with SCH (MF-S) compared with healthy controls (HC), (2) the degree to which pre- and post-synaptic factors contribute to increased striatal dopamine (DA) signaling in MF-S and (3) to test the hypotheses that optimal DA transmission in the dorsal caudate (DCA) is necessary for normal working memory (WM) function.
