This is the homepage of the research group Neurophysiology of Active Perception. We belong to the Donders Centre for Cognition, one of the three centres of the Donders Institute for Brain, Cognition and Behavior.
 
The general objective of our research program is to formulate and validate mechanistic explanations of cognitive phenomena, that is explanations in terms of their underlying neurophysiological mechanisms. Our focus is on active perception, that is perceptual phenomena that reflect the role of the perceiving organism (as opposed to the physical properties of the stimulus). Example phenomena are expectation, attention, recognition, and prediction. In our experiments, we measure neurophysiological activity using a variety of techniques: MEG, ECoG and EEG in humans, and invasive recordings in rats, both epidurally and in the neuropil. Most of our experiments target the somatosensory system which can be studied very well in humans using MEG and in rats using invasive recordings. Besides basic science, our research program also has a methodological and an applied component. The methodological component focuses on the characterization of interactions in spatially distributed neural activity. The applied component is brain-computer infacing (BCI).

  • The rhythm in your muscles reveals what you’re attending to; new paper by Freek van Ede and Eric Maris in The Journal of Neuroscience Neural oscillations in the beta band (15-30 Hz) are a defining feature of perhaps the most prominent network in the primate nervous system: the somatomotor network. These oscillations occur ...
