OBJECTIVES Studies on the relation between local cerebral activation and retrieval success usually compared high and low performance conditions, and thus showed performance-related activation of different brain areas. Only a few studies directly compared signal intensities of different response categories during retrieval. During verbal recognition, we(More)
Audio-visual integration in the human brain influences perception and precision of motor tasks. We tested audio-visual integration during height estimation when presenting video clips of counter movement jumps (CMJ), using sparse sampling fMRI at 3T. Employing the technique of "sonification", we created artificial auditory-visual motion events by(More)
The applicability of functional magnetic resonance imaging (fMRI) in patients with Alzheimer's disease (AD) or schizophrenia is frequently limited by cognitive impairment, which prevents the adequate execution of complex tasks. An experimental design that puts only minor demands on the patients' cognitive ability but engages disease-relevant brain(More)
