1 Cognitive Challenge Summary Analysis of Phase II data –240 sessions analyzed using BPutil pipeline, BIRN QA and Eventstats –ROI analysis of MFG, IPL, and STG –Comparison of FIPS and BPutil for Iowa data New task development –Emotional oddball (event-related) –Emotional executive (blocked) –Movie clips

7 Auditory Oddball

8 Auditory Oddball Summary Robust activations of dlPFC, IPL, STG, insula, cingulate, thalamus, and motor cortex –In all locations, controls > patients Strong visual cortex activation suggests that infrequent tones evoke an orienting response –Brainstem activation is also suggestive, but less visible in count conditions
