We used a whole-scalp magnetometer with 122 planar gradiometers to study the activity of the visual cortex of five blind humans deprived of visual input since early infancy. Magnetic responses were recorded to pitch changes in a sound sequence when the subjects were either counting these changes or ignoring the stimuli. In two of the blind subjects, magnetic resonance images were also obtained, showing normal visual cortex macroanatomy. In these subjects, the magnetic responses to counted pitch… Expand
The role of blind humans’ visual cortex in auditory change detection
TLDR
The auditory functions of this cortical region in early-blind humans by means of functional magnetic resonance imaging found that these areas were not activated by the mere presence of sound, but were involved in the attentive processing of changes in the auditory environment, which is important in detecting potentially dangerous or other important events in the surroundings.

Occipital Activation by Pattern Recognition in the Early Blind Using Auditory Substitution for Vision
TLDR
The results suggest that activity of the extrastriate visual cortex of early blind subjects can be modulated and bring additional evidence that early visual deprivation leads to cross-modal cerebral reorganization. Expand
Visual stimuli activate auditory cortex in deaf subjects: evidence from MEG
TLDR
Using MEG in deaf and hearing subjects to evaluate whether auditory cortex, devoid of its normal input, comes to serve the visual modality early in the course of stimulus processing adds to the mounting evidence that removal of one sensory modality in humans leads to neural reorganization of the remaining modalities. Expand
Different activation patterns in the visual cortex of late and congenitally blind subjects.
TLDR
It is demonstrated that congenitally blind subjects show task-specific activation of extrastriate visual areas and parietal association areas during Braille reading, compared with auditory word processing. Expand
Crossmodal audio-visual interactions in the primary visual cortex of the visually deprived cat: a physiological and anatomical study.
TLDR
The synaptic and anatomical basis of this phenomenon in cats that were visually deprived by dark rearing, either early visual deprived after birth (EVD), or late visually deprived after the end of the critical period (LVD) is studied and a striking decrease in pavalbumin- and calretinin-positive neurons is revealed. Expand
Short-term visual deprivation alters neural processing of tactile form
TLDR
It is concluded that blindfolding sighted individuals for a 2-h period induces significant changes in the neural processing of tactile form, probably reflecting short-term neural plasticity. Expand
Preparatory Activity in Occipital Cortex in Early Blind Humans Predicts Auditory Perceptual Performance
TLDR
The pattern of response in visual areas is similar to preparatory effects observed during visual selective attention in sighted subjects and consistent with the hypothesis that the mechanisms implicated in visual attention continue to modulate occipital cortex in the early blind. Expand
Functional cerebral reorganization for auditory spatial processing and auditory substitution of vision in early blind subjects.
Early blind (EB) individuals can recognize bidimensional shapes using a prosthesis substituting vision with audition (PSVA) and activate right dorsal extrastriate visual cortex during the executionExpand

Expansion of the Tonotopic Area in the Auditory Cortex of the Blind
TLDR
A part of the core area of the auditory cortex was examined by magnetic source imaging and was found to be enlarged by a factor of 1.8 in the blind compared with the sighted humans, consistent with and well suited to mediate the demonstrated increased ability of the blind to accurately localize acoustic sources in peripheral auditory fields and to decode speech.

TLDR
Results point to a possible role for the blind's visual cortex in tactile processes as measured by scalp-recorded event-related slow negative DC potential shifts in early blind mammals. Expand
Early visual deprivation alters modality of neuronal responses in area 19 of monkey cortex
TLDR
Recordings of multiple unit activity in the associative visual cortical area of deprived monkeys indicated that 20% of the neuron groups studies responded only during active somatic exploration, whereas in normal animals all neuron groups studied responses exclusively to visual stimuli, but in the deprived animals only 40% of them did.

Brain generators implicated in the processing of auditory stimulus deviance: a topographic event-related potential study.
TLDR
The results showed that, in all cases, the negative wave elicited by the deviant stimuli showed the highest amplitudes over the right hemiscalp irrespective of the ear of stimulation or the direction of attention, and this asymmetric potential distribution could be attributed to the sum of activities of two sets of neural generators.

Intermodal selective attention. I. Effects on event-related potentials to lateralized auditory and visual stimuli.
TLDR
The results suggest that sustained, intermodal attention depends primarily in processing modulations in modality-specific cortex, and does not index "template matching" operations. Expand
High metabolic activity in the visual cortex of early blind human subjects
TLDR
Observations raise the question of the functionality of the blind's visual cortex, as regional glucose utilization was the highest in the striate and prestriate cortical areas in early blind human subjects. Expand
Glucose utilization in human visual cortex is abnormally elevated in blindness of early onset but decreased in blindness of late onset
TLDR
This unexpected difference between early and late blind subjects might reflect the persistence, in early blindness, of supranumerary synapses which would escape the normal developmental decrease in synaptic density during infancy. Expand

TLDR
P Pitch deviance in a sequence of repetitive tone pips elicited magnetic evoked-response changes with a topography suggesting that a neuronal mismatch process to the deviant tones activates the primary auditory cortex. Expand
