Abstract

Recent findings of vestibular responses in part of the visual cortex--the dorsal medial superior temporal area (MSTd)--indicate that vestibular signals might contribute to cortical processes that mediate the perception of self-motion. We tested this hypothesis in monkeys trained to perform a fine heading discrimination task solely on the basis of inertial motion cues. The sensitivity of the neuronal responses was typically lower than that of psychophysical performance, and only the most sensitive neurons rivaled behavioral performance. Responses recorded in MSTd were significantly correlated with perceptual decisions, and the correlations were strongest for the most sensitive neurons. These results support a functional link between MSTd and heading perception based on inertial motion cues. These cues seem mainly to be of vestibular origin, as labyrinthectomy produced a marked elevation of psychophysical thresholds and abolished MSTd responses. This study provides evidence that links single-unit activity to spatial perception mediated by vestibular signals, and supports the idea that the role of MSTd in self-motion perception extends beyond optic flow processing.

  • Vestibular and visual signals are combined in macaque MSTd.

    “Neurophysiological work in macaque monkeys indicates that vestibular and visual signals are combined on the dorsal subdivision of the medial superior temporal area (MSTd) (6–11) and in the ventral intraparietal area (VIP) (12, 13).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
