Zusammenfassung
9 DPD patients were compared with 12 normal control volunteers in their cerebral activation patterns, levels of sympathetic outflow, and behavioral measures. Emotional facial expressions of happiness and sadness in three intensity levels (0%–50%–100%) were presented in an implicit ER-fMRI experimental paradigm combined with simultaneous online-recording of skin conductance levels. To obtain “pure“ emotion-induced cerebral activation, 100%–50% subtraction contrast maps were generated, thereby removing face-specific activation. Using 50%–100% emotion specific SCL aggregates, correlation overlap images were produce…
