abstract = {We recorded the responses of 189 medial superior temporal area ({MST}) neurons by using optic flow, real translational movement, and combined stimuli in which matching directions of optic flow and real translational movement were presented together. One-half of the neurons (48\%) showed strong responses to optic flow simulating self-movement in the horizontal plane, and 24\% showed strong responses to translational movement. Combining optic flow stimuli with matching directions of translational movement caused substantial changes in both the amplitude of the best responses (44\% of neurons) and the strength of direction selectivity (71\% of neurons), with little effect on which stimulus direction was preferred. However, combining optic flow and translational movement such that opposite directions were presented together changed the preferred direction in 45\% of the neurons with substantial changes in the strength of direction selectivity. These studies suggest that {MST} neurons combine visual and vestibular signals to enhance self-movement detection and disambiguate optic flow that results from either self-movement or the movement of large objects near the observer.},

Cells in MST respond to and are selective to optic flow.

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.
