Perceptually relevant remapping of human somatotopy in 24 hours

eLife, 2016
Experience-dependent reorganisation of functional maps in the cerebral cortex is well described in the primary sensory cortices. However, there is relatively little evidence for such cortical reorganisation over the short-term.

Computation identifies structural features that govern neuronal firing properties in slowly adapting touch receptors

eLife, 2014
Touch is encoded by cutaneous sensory neurons with diverse morphologies and physiological outputs. How neuronal architecture influences response properties is unknown.

Imaging Real-Time Tactile Interaction With Two-Person Dual-Coil fMRI

Frontiers in Psychiatry, 2020
Studies of brain mechanisms supporting social interaction are demanding because real interaction only occurs when persons are in contact. Instead, most brain imaging studies scan subjects individually.

A Tactile Virtual Reality for the Study of Active Somatosensation

Frontiers in Integrative Neuroscience, 2020
Natural exploration of textures involves active sensing, i.e., voluntary movements of tactile sensors (e.g., human fingertips or rodent whiskers) across a target surface.

Contrasting action and posture coding with hierarchical deep neural network models of proprioception

eLife, 2023
Biological motor control is versatile, efficient, and depends on proprioceptive feedback. Muscles are flexible and undergo continuous changes, requiring distributed adaptive control mechanisms that continuously account for the body’s state. The canonical

Shared Patterns of Brain Functional Connectivity for the Comorbidity between Migraine and Insomnia

Biomedicines, 2021
Migraine is commonly comorbid with insomnia; both disorders are linked to functional disturbance of the default mode network (DMN). Evidence suggests that DMN could be segregated into multiple subnetworks with specific roles that underline different ...

Differential postural effects of plantar-flexor muscles fatigue under normal, altered and improved vestibular and neck somatosensory conditions [PDF]

Experimental Brain Research (2008) 1-31, 2008
The aim of the present study was to assess the effects of plantar-flexor muscles fatigue on postural control during quiet standing under normal, altered and improved vestibular and neck somatosensory conditions. To address this objective, young male university students were asked to stand upright as still as possible with their eyes closed in two ...

Optimizing Movement Performance with Altered Sensation: An Examination of Multisensory Inputs

Brain Sciences, 2023
Two experiments were conducted to assess the impact of induced paresthesia on movement parameters of goal-directed aiming movements to determine how visual and auditory feedback may enhance performance when somatosensory feedback is disrupted.

Perceptual and Conceptual Distortions of Implicit Hand Maps

Frontiers in Human Neuroscience, 2015
Recent studies have revealed that human position sense relies on a massively distorted representation of hand size and shape. By comparing the judged location of landmarks on an occluded hand, Longo and Haggard (2010) constructed implicit perceptual maps

Somatosensory mismatch response in young and elderly adults

Frontiers in Aging Neuroscience, 2014
Aging is associated with cognitive decline and alterations in early perceptual processes. Studies in the auditory and visual modalities have shown that the mismatch negativity (or the mismatch response, MMR), an event-related potential (ERP) elicited by ...
