The paper investigates texture coding in higher order somatosensory cortices of macaques, finding that S2/PV neurons represent texture more sparsely and encode task-related information rather than the stimulus itself.

The paper presents a computational model of tactile perceptual bistability that incorporates hierarchical processing and captures key dynamical features of perceptual alternations.

The paper shows that Aδ-low threshold mechanoreceptors form tiled receptive fields through competition for hair follicles during early postnatal development.

The paper quantifies natural tactile scene statistics using 3D object scans and shows they resemble visual image statistics, with neural models capturing primate somatosensory cortex responses.

This study develops a parametric model linking trigeminal nerve stimulation intensity to blink response properties, finding a laterality effect in half-response thresholds.

This study shows that early deafness leads to cross-modal reorganization in auditory cortices, which functionally couples with frontoparietal and default-mode networks, affecting visuomotor transformation performance.

The paper shows that columnar scale lesions in mouse vS1 impair tactile discrimination but not detection.

The paper investigates whether alpha oscillations in early blind individuals are modulated by tactile attention, finding that occipital alpha activity is sensitive to task-dependent factors despite reduced amplitude.

The paper identifies a neural mechanism in the mouse superior colliculus that distinguishes external from self-generated tactile motion using whisker-specific adaptation and sensorimotor predictions.

This study uses 7 Tesla MRI to find structural brain reductions in congenitally blind individuals compared to sighted controls, including grey and white matter changes across multiple brain regions.

This study finds that blind individuals have better accuracy in detecting their heartbeat compared to sighted controls, suggesting enhanced cardiac interoception due to visual deprivation.

The paper shows that individual tactile pleasantness follows a velocity-dependent quadratic function across skin types, with stability and trait-like characteristics.

The paper was withdrawn due to an error in the data processing pipeline, and the authors do not wish it to be cited.

The paper develops a tactile perception task and uses EEG and eye metrics to identify neural and physiological correlates of conscious tactile perception.

The paper shows that vibrotactile working memory modulates somatotopic finger representations in primary somatosensory cortex during the delay period without tactile stimulation.

This study investigates neural changes during vibrotactile speech learning, showing integration with auditory speech systems through fMRI and EEG.

The paper uses fMRI to show that human neocortex responses are tuned for vibration frequency, reflecting perceptual sensitivity and Pacinian afferent system responses.

The paper uses fMRI to compare cross-modal responses in visual cortex of congenitally blind, adult-onset blind, and sighted individuals, finding that visual cortex plasticity for auditory processing occurs only in those born blind.

This study investigates the subjective experience and physiological responses to ultrasound stimulation, finding age-related differences in intensity and pleasantness ratings and no activation of specific mechanoreceptors.

The paper investigates differences in nucleus basalis of Meynert plasticity between early and late blind individuals using MRI, finding greater functional connectivity in early blind individuals despite similar white matter integrity reduction.

This paper develops a portable system for blind and visually impaired users to read printed text through electro-Braille feedback using opto-electrotactile technology.

This paper shows that transcranial magnetic stimulation of the visual cortex disrupts motor function in acquired blind individuals but not congenitally blind or sighted individuals.

The paper investigates whether tactile responses in the visual cortex of a visually impaired individual are causally linked to tactile processing performance using TMS and fMRI.

The paper identifies a neural link between the lateral occipital cortex and inferior frontal cortex in late blind individuals and shows it correlates with Braille reading proficiency.

The paper investigates finger representation in the primary somatosensory cortex of congenitally blind individuals using fMRI and psychophysics, finding no increased hand representation but activation of the middle temporal complex during finger movement.
