Our aim is to understand the dynamic mechanisms of neuronal information processing at the level of well-defined neuronal networks. Currently, research concentrates on the cortical visual system (areas V1, V2, V4, and MT), in particular the functional mechanisms underlying selective attention and attention-dependent signal routing and circuit configuration. The methods used for this purpose include single unit and local field potential recordings in monkeys trained to well-defined behavioral tasks as well as behavioral and psychophysical approaches. In parallel, we constantly develop and implement new techniques like high resolution epidural grid recordings and techniques for chronic recording with microelectrode arrays. The goal is to provide reliable and safe methods which maximize the amount and spatio-temporal resolution of acquired neuronal brain signals, allow influencing dynamic states of neural processing while minimizing interference with the brain tissue. In both lines of research we closely collaborate with theoretical neuroscientists and engineers (microsystems technology, electrical and communications engineering), respectively.
