Decoding Belief Decision Making with Decision Tree Classifiers.

Decision making in the brain is thought to be a hierarchical process that activates uniquely distributed brain regions in accordance with the decision outcome. We collected both EEG and fMRI data while subjects determined the veracity of statements, which ranged categorically from autobiographical to mathematical assessments. Independent components, derived separately from each modality, were then used as decoding features to predict the subjects decision response. This lecture will focus on discussing the use of decision tree pattern classification algorithms for decoding decision making in the brain, and the extent to which one can interpret these findings.
