Projects:FractionalAnisotrophyInTheUncinateFasciculus

Back to NA-MIC_Collaborations

Objective: To measure the FA in the uncinate fasciculus in patients with schizophrenia. This project is based on the methods published by Kubicki et al. and extends that work by including a bipolar disorder control group, and determining whether there is an association between FA and cognitive functioning and symptoms in the patient groups.

Progress: DTI data has been collected in 12 patients with schizophrenia, 15 healthy controls and 8 patients with bipolar disorder. Initial practice at identifying coronal slice of uncinate fasciculus completed (see figure below for example). Visit to Dartmouth by Dr. Kubicki to discuss methodology. A link to sample DTI data is available below.
