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.
