How the brain merges the senses

In his experiments, Dr. Cesare Parise had test subjects observe and evaluate random flashes of light and clicks to uncover out how the brain connects sensory stimuli – and keeps them apart. Credit: CITEC/ Bielefeld University Utilizing information from all the senses is critical for building a robust and rich representation of our surroundings. Given the wealth of multisensory information constantly bombarding us, however, how does our brain know which signals go together and thus need to be combined? And how does it integrate such related signals? Scientists from the Cluster of Excellence Cognitive Interaction Technology (CITEC) at Bielefeld University and the Max Planck Institute for Biological Cybernetics have proposed a computational model that explains multisensory integration in humans utilizing a surprisingly simple processing unit. This research, funded by the…
