DESCRIPTION:Human communication relies on quasi-rhythmic signals such as s
 peech and face movements. In addition\, the visual system also samples the
  environment in a quasi-rhythmic way. I will show examples of rhythmicity 
 in sensory sampling and discuss how this relates to brain oscillations. Sp
 ecifically\, brain oscillations seems to match the dominant spectral struc
 ture of relevant sensory stimuli. This is potentially relevant because low
 -frequency brain oscillations represent changes in excitability of neural 
 populations. I will demonstrate that phase resetting is a potentially powe
 rful mechanism for coding of sensory information and for aligning temporal
  windows of high neural excitability to salient events in sensory stimuli.
 \nShort Biography\nJoachim Gross is Professor of Systems Neuroscience\, Ac
 ting Director of the Centre for Cognitive Neuroimaging and Wellcome Trust 
 Senior Investigator. His group investigates the functional role of brain o
 scillations using Neuroimaging and computational methods. His main goal is
  to understand how brain oscillations support perception and action. He ob
 tained his M.Sc in Physics and Mathematics in San Angelo\, USA in 1993 and
  his degree in Physics in Hannover\, Germany in 1995. He was Ph.D. student
  at the Institute of Medicine\, Research Center Juelich and the MPI for Co
 gnitive Neuroscience in Leipzig. In 1998 he started working as a PostDoc i
 n the Clinic of Neurology at the University of Duesseldorf on pathological
  oscillatory brain processes in movement disorders and pain. In 2006 he wa
 s appointed Professor at Glasgow University. His method of choice is magne
 toencephalography (MEG). \n
