Description: Neuroscience Seminar Series

Pieter R. Roelfsema is Director of the Netherlands Institute for Neuroscience in Amsterdam, an Institute of the Royal Academy of Arts and Sciences of the Netherlands. He received his MD degree at the University of Groningen in the Netherlands in 1991. For his PhD, he worked with Wolf Singer at the Max-Planck-Institute for Brain Research in Frankfurt (Germany) on the visual system of the cat and the role of neuronal synchronization. He received his PhD degree at the University of Amsterdam in 1995. His studies center on visual perception, plasticity and memory in the visual system. He uses multi-electrode recording techniques in experimental animals, behavioral paradigms in humans, and computational neuroscience approaches. His work begins with the premise that perceptual or cognitive processes activate many areas of the cerebral cortex. The neurons in these areas must co-ordinate their activity and exchange information, but little is known about the mechanisms that are responsible for this information exchange. One of these perceptual processes is perceptual grouping, that is, the organization of elements in a visual scene that belong to the same object, and this is the topic of his lecture today.
