Objective: To determine if blind people have heightened tactile spatial acuity. Background: Recently, studies using magnetic source imaging and somatosensory evoked potentials have shown that the cortical representation of the reading fingers of blind Braille readers is expanded compared to that of fingers of sighted subjects. Furthermore, the visual cortex is activated during certain tactile tasks in blind subjects but not sighted subjects. The authors hypothesized that the expanded cortical…

Tactile Acuity is Enhanced in Blindness
Compared the passive tactile acuity of blind and sighted subjects on a fully automated grating orientation task and used multivariate Bayesian data analysis to determine predictors of acuity, the results suggest that crossmodal plasticity may underlie tactile Acuity enhancement in blindness.
Tactile Spatial Acuity Enhancement in Blindness: Evidence for Experience-Dependent Mechanisms
Results clearly implicate reliance on the sense of touch as the trigger for tactile spatial acuity enhancement in the blind, and suggest the action of underlying experience-dependent neural mechanisms such as somatosensory and/or cross-modal cortical plasticity.
Performance of blind and sighted humans on a tactile grating detection task
The superior tactile acuity of blind persons may result from the involvement of normally visually responsive cerebrocortical areas in tactile processing, as shown by functional-imaging studies.
Braille character discrimination in blindfolded human subjects
It is suggested that visual deprivation speeds up Braille learning and may be associated with behaviorally relevant neuroplastic changes.
Vibrotactile Masking Experiments Reveal Accelerated Somatosensory Processing in Congenitally Blind Braille Readers
Braille reading speed correlated significantly and specifically with masking task performance, and in particular with the backward masking decay time constant, suggesting that perceptual processing is accelerated in congenitally blind Braille readers.
What drives tactile spatial acuity enhancement in the blind
An important unresolved question in sensory neuroscience is whether, and if so with what time course, tactile perception is enhanced by visual deprivation. In three experiments involving 158 normally
Retention of high tactile acuity throughout the life span in blindness
It is proposed that blind people's use of active touch in daily activities, not specifically braille reading, results in preservation of tactile acuity across the life span, unlike their aging sighted peers.


Activation of the primary visual cortex by Braille reading in blind subjects
In blind subjects, cortical areas normally reserved for vision may be activated by other sensory modalities, and positron emission tomography was used to determine whether the visual cortex receives input from the somatosensory system.
The limit of tactile spatial resolution in humans
The grating orientation discrimination task provides a stable, reliable measure of the human capacity for spatial resolution, and psychophysical thresholds for tactile spatial resolution are obtained from 15 normal, young adult subjects over seven test sessions.
Perceptual Correlates of Changes in Cortical Representation of Fingers in Blind Multifinger Braille Readers
Magnetic source imaging indicated that the cortical somatosensory representation of the fingers was frequently topographically disordered in blind Braille readers; in addition, they frequently misperceived which of these fingers was being touched by a light tactile stimulus.
Plasticity of the sensorimotor cortex representation of the reading finger in Braille readers.
It is suggested that reading Braille is associated with expansion of the sensorimotor cortical representation of the reading finger, and somatosensory evoked potentials evoked from the reading fingers are significantly larger.
Different activation patterns in the visual cortex of late and congenitally blind subjects.
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.
Effects of selective attention on spatial form processing in monkey primary and secondary somatosensory cortex.
The effects of selective attention were studied in SI and SII cortex of a rhesus monkey trained to perform two tasks, a tactile discrimination task and a visual detection task, with significant differences between the discharge rates evoked by raised letters in the two tasks.
Tactile spatial acuity and roughness discrimination: Impairments due to aging and Parkinson's disease
It is concluded that Parkinson's disease significantly impairs performance on these tactile tasks, including tactually discriminating grating roughness and difference limens.
Spatial pattern representation and transformation in monkey somatosensory cortex.
Embossed letters were used to study the spatial patterns of neural activity evoked in peripheral fibers and cortical neurons in areas 3b and 1 of the primary somatosensory cortex of alert rhesus (Macaca mulatta) monkeys to investigate the representation and transformation of spatial information during the early stages of peripheral and cortical neural processing.
Tactile learning is task specific but transfers between fingers
It is concluded that tactile learning, although quite as task specific as in other sensory systems, generalizes with considerable facility across fingers, unlike visual learning, which is highly location specific.
Touch-perception thresholds in blind diabetic subjects in relation to the reading of Braille type.
Touch-perception thresholds were measured in 10 healthy seeing, 10 nondiabetic blind and 10 diabetic blind subjects to find out whether the difficulty of the diabetic subjects in reading Braille is probably related to an inability to perceive the individual points clearly.
