A Vestibular Sensation: Probabilistic Approaches to Spatial Perception

摘要: The vestibular system helps maintain equilibrium and clear vision through reflexes, but it also contributes to spatial perception. In recent years, research in the field has expanded higher-level processing involving cortex. Vestibular contributions cognition have been difficult study because circuits involved are inherently multisensory. Computational methods application of Bayes theorem used form hypotheses about how information from different sensory modalities is combined together with expectations based on past experience order obtain optimal estimates cognitive variables like current orientation. To test these hypotheses, neuronal populations being recorded during active tasks which subjects make decisions visual or somatosensory information. This review highlights what currently known role processes, computations necessary appropriate signals, benefits that emerged thus far.
