Secondary somatosensory area is involved in vibrotactile temporal-structure processing: MEG analysis of slow cortical potential shifts in humans

Abstract

Examples of single-subject data showing subject-tosubject variation in the active-irregular condition.

Neural Sources of Vagus Nerve Stimulation–Induced Slow Cortical Potentials

“…elicited by VNS without the participants' awareness, they may have an electrophysiological nature similar to that of sustained SCPs evoked by sensory stimuli. The VNS activating the lateral part of the postcentral gyrus and insula is consistent with previous studies reporting that the sensory cortex of each modality is the origin for sustained cortical responses to auditory, 14 somatosensory, 15 and visual 16 stimuli. In addition to these well-known measures in the research field of event-related potentials, focal SCPs accompanying epileptic seizures 17,18 are important for understanding the neural mechanisms of SCPs.…”

Neural correlates of tactile hardness intensity perception during active grasping

“…Still, to further optimize the task design, future studies could use a visual feedback that shows an EMG-based gage to inform participants of their exerted force in real-time. In addition, in an experiment with real-time EMG, we could observe neural responses during tactile information processing using EEG or MEG with finer time resolution ( Golnaz et al, 2020 ; Hagiwara et al, 2020 ), which would help confirm the relationship between muscle strength and neural responses in real-time.…”
