Cells in MST respond to vestibular motion cues.

Some cells in MST are multisensory.

Visuo-vestibular cells in MST perform multisensory integration in the sense that their response to multisensory stimuli is different from their response to either of the uni-sensory cues.

Visuo-vestibular cells tend to be selective for visual and vestibular self-motion cues which indicate motion in the same direction.

The responses of some visuo-vestibular cells were enhanced, that of others was depressed by combined visuo-vestibular cues.

Visual information seems to override vestibular information in estimating heading direction.

Ideal observer models of cue integration were introduced in vision research but are now used in other uni-sensory tasks (auditory, somatosensory, proprioceptive and vestibular).

Morgan et al. studied the neural responses to visual and vestibular self-motion cues in the dorsal portion of the medial superior temporal area (MSTd).

They presented congruent and incongruent stimuli at different levels of reliability and found that at any given level of reliability, the neural computation underlying multi-sensory integration could be described well by a linear addition rule.

However, the weights used in combining the uni-sensory responses changed with cue reliability.

Studies of single-neuron responses to multisensory stimuli have over-emphasized the prevalence of superadditivity over that of subadditivity.
