The Dartmouth Driving Biological Project examines DW-MRI and fMRI data in patients with schizophrenia to determine association with brain activation during memory tasks.
  
A brief overview of the Dartmouth's driving biological problem goes here.  This should not be much longer than a paragraph.  Remember that people visiting your site want to be able to understand very quickly what you're all about and then they want to jump into your site's projects.  The projects below are organized into a two column table:  the left column is for representative images and the right column is for project overviews.  The number of rows corresponds to the number of projects at your site.  Put the most interesting and relevant projects at the top of the table.  You do not need to organize the table according to subject matter (i.e. do not group all segmentation projects together and all DWI projects together).

Brain Activation during Continuous Verbal Encoding and Recognition Task in Schizophrenia

This project employs an event-related auditory verbal episodic memory probe targeting medial temporal and DLPFC circuitry. The task uses a continuous performance format where concrete nouns are presented initially as new items.
