Decision and Awareness Group German Primate Center

Research

Cognitive and visuomotor functions in primates, with a focus on pulvinar, pulvinar-cortical and bihemispheric processing underlying decision-making in the context of goal-directed eye and hand movements, using neurophysiology, causal interference (inactivation, microstimulation) and functional imaging. Comparative human-monkey neuroimaging. Metacognition and social decision-making. Neurophysiology of active vision in primary visual cortex.
