Tactile Spatial Acuity Enhancement in Blindness: Evidence for Experience-Dependent Mechanisms
TLDR
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.
A Physical Constraint on Perceptual Learning: Tactile Spatial Acuity Improves with Training to a Limit Set by Finger Size
TLDR
The hypothesis that tactile perceptual learning is limited by finger size is supported, and it is suspected that analogous physical constraints on perceptual learning will be found in other sensory modalities.
Short-Term Visual Deprivation Does Not Enhance Passive Tactile Spatial Acuity
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
A Tactile Automated Passive-Finger Stimulator (TAPS)
TLDR
A computer-controlled tactile stimulus system, the Tactile Automated Passive-finger Stimulator (TAPS), that applies spatially structured stimuli to the skin, controlling for onset velocity, contact force, and contact duration is described.
How does the Visual Cortex of the Blind Acquire Auditory Responsiveness?
TLDR
The authors concluded, based on their modeling results, that V1 activation in the blind is most likely driven by auditory inputs arising from the primary auditory cortex (A1), and found that the A1–V1 connection strength was greater in blind than in sighted participants.
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
