Abstract

The goal of this study was to characterize multisensory interaction patterns in cortical ventral intraparietal area (VIP). We recorded single-unit activity in two alert monkeys during the presentation of visual (drifting gratings) and tactile (low-pressure air puffs) stimuli. One stimulus was always positioned inside the receptive field of the neuron. The other stimulus was defined so as to manipulate the spatial and temporal disparity between the two stimuli. More than 70% of VIP cells showed a significant modulation of their response by bimodal stimulations. These cells included both bimodal cells, i.e., cells responsive to both tested modalities, and seemingly unimodal cells, i.e., cells responding to only one of the two tested modalities. This latter observation suggests that postsynaptic latent mechanisms are involved in multisensory integration. In both cell categories, neuronal responses are either enhanced or depressed and reflect nonlinear sub-, super-, or additive mechanisms. The occurrence of these observations is maximum when stimuli are in temporal synchrony and spatially congruent. Interestingly, introducing spatial or temporal disparities between stimuli does not affect the sign or the magnitude of interactions but rather their occurrence. Multisensory stimulation also affects the neuronal response latencies of bimodal stimuli. For a given neuron, these are on average intermediate between the two unimodal response latencies, again suggesting latent postsynaptic mechanisms. In summary, we show that the majority of VIP neurons perform multisensory integration, following general rules (e.g., spatial congruency and temporal synchrony) that are closely similar to those described in other cortical and subcortical regions.

  • PPS neurons are multisensory, responding to visual, tactile, and auditory stimuli.

    “Another critical feature of these neurons is that they are multisensory, they respond to visual, tactile, and auditory stimuli”

    From The Peripersonal Space in a social world (2021) · cites this paper as Avillac, Hamed, & Duhamel, 2007

    The Results report that many VIP neurons responded to both visual and tactile stimuli, and General experimental procedures notes that auditory responses have also been described in VIP. This study tested visual and tactile stimuli, however; it does not establish that the same neurons respond to all three modalities or that the finding applies to PPS neurons generally.

  • This precise temporal rule fits well with the temporal window of integration of multisensory cortical neurons, causal inference theories of multisensory integration, and the past body representation literature.

    “This precise temporal rule fits well with the temporal window of integration of multisensory cortical neurons12, causal inference theories of multisensory integration7,11,13, and the past body representation literature2,3,5,7–11,14,15.”
  • These multisensory cells are sensitive to the temporal and spatial congruency of multisensory signals.

    “Furthermore, these multisensory cells are sensitive to the temporal and spatial congruency of multisensory signals [47].”

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.
