'''Objective:''' In this project, an event-related auditory semantic memory task is administered. Participants are presented with a semantic category and required to decide whether a subsequent word is a member of the category (e.g., vehicle-bus). To control for phonological processing, other items require a match-mismatch decision between pseudo-words constructed from reordered semantic items (e.g., yodb-rea).

Objective: Imporving the accuracy of activation detection in fMRI through incorporation of sophisticated prior models on activation, including anatomical priors.

Progress:

The work on MRF-based regularization of the fMRI activation maps was presented at IPMI last summer. The algorithm implementation in Slicer is underway in collaboration with BWH. Our plans include releasing the code into the itk libaray.
