Spatial Processing and the Brain’s Sensory Systems

Published on May 18, 2023

From navigating through different terrains to crossing busy streets, our brain faces the challenge of accurately locating objects and events. This is because the information our sensory systems provide about the environment is noisy and constantly changing. To overcome this, our brain engages in a process called multisensory integration, where it combines redundant information from different senses to improve localization precision. By leveraging the strengths of multiple senses, our brain increases its ability to navigate and interact with the world around us. To learn more about the fascinating ways in which our brain processes spatial information, check out the full article below!

From hunting prey and evading predators in the forests and savannahs to crossing busy city streets, the ability to precisely and accurately locate objects and events in the environment has remained one of the most fundamental challenges that our cognitive system needs to solve. This is so because spatial cues (see Glossary) derived from the neural signals originating in our peripheral sensory systems are inherently noisy [1] and constantly changing [2]. To increase localization precision and accuracy, the brain engages in multisensory integration, a process that takes advantage of the fact that the sensory systems provide partially redundant information about the world.
