Diminished Signal‐to‐Noise Ratio Disrupts Somatosensory Population Encoding and Drives Tactile Hyposensitivity in the Fmr1−/y Autism Model

Advanced Science, EarlyView.
This study provides a translational approach for linking neural activity to tactile deficits in autism. By combining psychophysics with cortical recordings in a mouse model of autism, we show that low signal‐to‐noise ratio in somatosensory neurons weakens population encoding of fine touch, impairing detection, decoding, and leading to perceptual ...

Optimality of multisensory integration while compensating for uncertain visual target information with artificial vibrotactile cues during reach planning

Journal of NeuroEngineering and Rehabilitation
Background Planning and executing movements requires the integration of different sensory modalities, such as vision and proprioception. However, neurological diseases like stroke can lead to full or partial loss of proprioception, resulting in impaired ...

Independent component approach to the analysis of EEG and MEG recordings [PDF]

, 2000
Multichannel recordings of the electromagnetic fields emerging from neural currents in the brain generate large amounts of data. Suitable feature extraction methods are, therefore, useful to facilitate the representation and interpretation of the data ...

A Large‐Area Broadband Multimodal Dual‐Resonant Haptic Device for Bidirectional Telerobotic and Augmented Interactions

Advanced Science, EarlyView.
We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

Cortical activations induced by electrical versus vibrotactile finger stimulation using EEG

NeuroImage
Somatosensory evoked potentials (SEPs) recorded with electroencephalography offer insights into cortical responses to tactile stimulation, typically elicited through temporally precise electrical stimulation.

INVESTIGATING THE ROLES OF MECHANORECEPTIVE CHANNELS IN TACTILE APPARENT MOTION PERCEPTION: A VIBROTACTILE STUDY [PDF]

, 2018
Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this.

Useful residual hearing despite radiological findings suggestive of anacusis [PDF]

, 1999
A severe malformation of the inner ear, often referred to as severe labyrinthine dysplasia or common cavity deformity, consists of an absent or dilated cochlear basal coil, wide communication with the vestibule and a tapered internal acoustic meatus and ...

Affective CT‐touch attenuates cortical responses and subjective attention during temporal summation of second pain

The Journal of Physiology, EarlyView.
Abstract figure legend The study investigated the modulatory effects of affective touch on temporal summation of second pain (TSSP) in 32 romantic couples (N = 64). The design included a dyadic session (partner's CT‐optimal stroking vs. static touch) and an individual session (robotic CT‐touch vs. vibration control).
