My fundamental interest is in how changes in neural activity, on the time scale of milliseconds to seconds, impact information processing. The specific focus of our work is understanding the role of the neocotex in sensation. We seek to understand the mechanisms underlying these dynamics-for example, how neurons can rapidly shift their sensitivity to a given sensory input-and their meaning for perception-for example, how ongoing oscillations enhance or suppress probability of accurate behavioral detection of a sensory input.

Control of information flow between neurons or groups of neurons is essential in a functional brain, e.g. for context and brain state dependent processing. In line with recent experimental and theoretical studies [1,2] we show that phase relations between synchronized oscillatory local circuits or brain areas may dynamically create information channels and induce changes in the effective connectivity.

Beta band (13-30 Hz) oscillations in sensorimotor cortex are associated with motor performance, but the nature of this relationship is not clear. Recently, excessive beta activity in cortico-basal ganglia circuits has been recognized as a hallmark of Parkinson’s disease. Renewed interest in beta oscillations has since led to the suggestion that they might reflect the preservation of the current output or state of a given brain region.
