Data from: Shared neural underpinnings of multisensory integration and trial-by-trial perceptual recalibration in humans

Perception adapts to mismatching multisensory information, both when
different cues appear simultaneously and when they appear sequentially.
While both multisensory integration and adaptive trial-by-trial
recalibration are central for behavior, it remains unknown whether they
are mechanistically linked and arise from a common neural substrate. To
relate the neural underpinnings of sensory integration and recalibration,
we measured whole-brain magnetoencephalography while human participants
performed an audio-visual ventriloquist task. Using single-trial
multivariate analysis, we localized the perceptually-relevant encoding of
multisensory information within and between trials. While we found neural
signatures of multisensory integration within temporal and parietal
regions, only medial superior parietal activity encoded past and current
sensory information and mediated the perceptual recalibration within and
between trials. These results highlight a common neural substrate of
sensory integration and perceptual recalibration, and reveal a role of
medial parietal regions in linking present and previous multisensory
evidence to guide adaptive behavior.
