Quantifying Abnormalities in Cortical Activation Associated With Auditory Hallucinations Using Functional Magnetic Resonance Imaging
Completed · Not applicable
Conditions studied: Schizophrenia, Schizoaffective Disorder, Hallucinations
In brief
The goal of the project is to characterize abnormalities in brain structure and function related to schizophrenia. The investigators will use advanced magnetic resonance imaging (MRI) techniques to measure the degree and distribution of neuronal activity during specific cognitive tasks, alterations in neuronal connectivity, and how these are related to disease symptoms and treatment.
