This study examines how early sensory loss affects thalamocortical networks, finding structural and functional changes in visual and auditory systems.

The paper investigates how early blindness alters the feedforward motion processing in hMT+/V5, showing a shift from visual to auditory input.

This study uses MEG to investigate how early visual cortex supports lexical and semantic processing in sighted and blind individuals, finding task-specific decoding differences in occipital areas.

The paper investigates ocular speech tracking in blind and sighted individuals, finding it is not modulated by speech intelligibility and has two frequency-specific components influenced by visual experience.

This study shows early sensory deprivation causes localized reorganization near deprived primary sensory areas while preserving the overall cortical hierarchy.

The paper compares computational models' processing of visual Braille with human neural data, finding that feedforward models fail to replicate human expertise in visual Braille processing.

The paper shows that hMT+/V5 and fronto-parietal regions encode visual and tactile motion directions using a common external frame of reference, independent of body posture.

The paper investigates serial dependence across vision and audition, showing it transfers between modalities and is influenced by cross-modal attention, with neural evidence from EEG recordings.

The paper investigates how emotional expressions are represented in brain networks for facial and vocal signals, finding shared neural codes and multisensory integration across regions.

This study shows that early visual deprivation in humans impairs the early visual cortex but leaves the categorical coding in the ventral occipito-temporal cortex largely unaffected.

This study finds a significant association between cortical thickness in occipital regions and functional activation during linguistic processing in early blind individuals.

This study investigates how the brain represents numerical information across different senses and formats using fMRI, finding consistent encoding in specific brain regions and a shift in representation factors along the intraparietal sulcus.

The paper investigates how pre- and post-stimulus neural states predict perceived audio-visual synchrony using MEG and frequency-tagging analysis.

This study identifies brain regions encoding both auditory and visual speech using fMRI, showing that the VWFA and lSTS represent phonological information from both modalities, with distinct alignment patterns.

This study compares cortical gradients in congenitally blind and sighted adults to assess the role of genetics and experience in shaping functional connectivity.

This study investigates how the brain processes visual Braille by comparing expert and naive readers, finding that linguistic content, not visual features, drives orthographic decoding in an extended reading network.

The paper investigates whether magnitude integration effects arise from perceptual processes or decision-making by comparing task-based and passive viewing conditions.

This study uses resting-state fMRI and a hidden Markov model to show that early visual deprivation alters temporal dynamics and spatial organization of brain networks in blind individuals.

This study investigates the mechanisms and EEG signature of average numerosity perception using dynamic stimuli and shows perceptual adaptation effects and early brain responses related to numerical judgments.

This study finds that blind individuals perform worse than sighted controls in discriminating threat-related vocal emotions like anger and fear.

This study uses EEG and an oddball paradigm to show the brain automatically categorizes non-verbal vocal emotions independently of acoustic features.

The paper investigates the temporal dynamics of abstract and concrete semantic representations using MEG, finding early frontotemporal activation for both and later occipito-temporal responses to concrete features.

The paper shows that congenitally blind individuals maintain connectivity between visual and sensorimotor cortices, with eye movements driving visual cortex activity and sensorimotor activity, despite lacking visual experience and oculomotor control.

The paper investigates shape representation in the human brain by comparing early blind and sighted participants, finding that the inferolateral occipitotemporal cortex (ILOTC) encodes shape information independently of visual experience.

This study examines how blindness onset affects sound category representation in occipital and temporal cortices, finding enhanced and stable coding in occipital regions and a reverse pattern in temporal regions in blind individuals.

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 investigates how early blindness affects brain networks involved in spatial hearing, finding enhanced motion direction coding in hMT+/V5 and reduced coding in hPT in blind individuals.

The paper investigates neural responses to narrative and argumentative texts using fMRI, finding shared and distinct brain network activations.

The paper uses FPAS and EEG to show robust voice-selective brain responses independent of low-level acoustic features, demonstrating automatic voice categorization.

This study shows that early deafness leads to visual motion processing in auditory motion-selective brain regions and altered functional connectivity between auditory and visual motion areas.
