Research expertise

Our laboratory focuses on two research themes:

  1. How neurons signal visual stimuli, specifically the synchronization of action potentials evoked by nerve impulse trains from distinct cells.
  2. How neurons change their properties by visual learning, which means that we are investigating neuronal plasticity, or the neural correlate of memory. Neurons are presented with a non-preferred stimulus for several minutes. Following this adaptation, many cells shift their preferred stimulus in the direction of the adapter. We are studying the mechanisms of this shift.
