computation

Fundamental observations and principles derived from
traditional physiological studies of multisensory integration
have been difficult to reconcile with computational and
psychophysical studies that share the foundation of
probabilistic (Bayesian) inference. We review recent work on
multisensory integration, focusing on experiments that bridge
single-cell electrophysiology, psychophysics, and
computational principles. These studies show that
multisensory (visualvestibular) neurons can account for near-
optimal cue integration during the perception of self-motion.
Unlike the nonlinear (superadditive) interactions emphasized in
some previous studies, visualvestibular neurons accomplish
near-optimal cue integration through subadditive linear
summation of their inputs, consistent with recent
