Perception is something that must be learned. As we recognize things in our environment we gather experience and this experience in turn colours our perception. This is nothing new, of course. But brain researchers are going one step further to ask how different kinds of information are integrated in the brain and what principles govern how perceived objects are represented there. Scientists at Tuebingen's Max Planck Institute for Biological Cybernetics have carried out experiments that prove for the first time that single nerve cells in the brain are responsible for controlling our perception by drawing on prior experience. They report their findings in the latest issue of the journal "nature" (nature, January 17, 2002).
