How is it possible for the brain to recognise drawn objects as houses or animals? In a recent study in the Journal of Neuroscience, scientists from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, in collaboration with the Freie Universität Berlin and Justus Liebig University Giessen, investigated how our perception of line drawings differs from natural images. The researchers show that the perception of objects is particularly robust to changes in our environment.
