We examined the spatial organization of perceptual learning in a cortex-dependent task. Rats learned a tactile task using four whiskers on one side of the snout, all others being clipped. These trained whiskers were then clipped and prosthetic whiskers were attached. Subsequent performance was found to be determined by the location of the prosthetic whiskers. There was partial transfer of learning to neighbouring whisker positions. In addition, there was partial transfer of learning to whisker…

The Topography of Tactile Learning in Humans
TLDR
The results indicate that tactile learning is organized within a somatotopic framework, reconciling the findings in humans with those in other species.
Integration of bilateral whisker stimuli in rats: role of the whisker barrel cortices.
TLDR
The findings presented here indicate that rats can solve a task that requires the conjoint detection of left and right whisker-mediated distance information and implicate the SIws as central to this ability.
Deficits in Behavioral Functions of Intact Barrel Cortex Following Lesions of Homotopic Contralateral Cortex
TLDR
The findings indicate that the prolonged impairment in execution of the learnt task by rats with unilateral lesions of somatosensory cortex could be because sensory inputs from one set of whiskers to the intact cortex is insufficient to provide adequate sensory information at higher thresholds of detection.
Learning of tactile frequency discrimination in humans
TLDR
The purpose of the present study was to examine the extent to which training‐induced improvements in tactile frequency discrimination in humans are correlated with an increase of cortical representations in the primary somatosensory cortex.
Early‐phase of learning enhances communication between brain hemispheres
TLDR
Sensory stimulation directed to one cerebral hemisphere during the initial stages of Pavlovian conditioning activates the primary sensory area in both hemispheres, suggesting that during the early phase of conditioning, the interhemispheric interactions are enhanced.
Bilateral representations of touch in the primary somatosensory cortex
ABSTRACT According to current textbook knowledge, the primary somatosensory cortex (SI) supports unilateral tactile representations, whereas structures beyond SI, in particular the secondary…
Chapter 24 – Somatosensory System
Long-Term Synaptic Plasticity in Rat Barrel Cortex.
TLDR
It is suggested that natural rhythmic whisker activity modifies sensory information processing in cerebral cortex, providing further insight into sensory perception.
Transfer of tactile perceptual learning to untrained neighboring fingers reflects natural use relationships
TLDR
The results support the theory that tactile coactivation patterns between digits affect their topographic relationships and emphasize how action shapes perception and somatosensory organization.
Tactile learning transfer from the hand to the face but not to the forearm implies a special hand-face relationship
TLDR
It is suggested that RSS-induced tactile learning transfers preferentially from the hand to the face rather than to the forearm, reflecting a fundamental coupling between these body parts.

Tactile learning is task specific but transfers between fingers
TLDR
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.
Perceptual learning in tactile hyperacuity: complete intermanual transfer but limited retention
TLDR
Investigation of intermanual transfer and long-term retention of practice-related perceptual learning in the domain of tactile hyperacuity found that interManual transfer of tactile learning appears to be a general phenomenon, while long- term retention appears to been limited in hyperACuity tasks.
The sensory contribution of a single vibrissa's cortical barrel.
TLDR
The results of repeated retesting of an individual rat's ability to make a jump-no jump decision on the basis of vibrissa-transduced information at each stage of a series of successive single-vibrissa removals and unilateral barrelfield ablations show that the loss of the cortex containing the vibrissa's contralateral barrel is tantamount to loss ofThe vibrissa itself.
Human perceptual learning in identifying the oblique orientation: retinotopy, orientation specificity and monocularity.
TLDR
Human perceptual learning in discrimination of the oblique orientation was studied using psychophysical methods and suggests plastic changes at a level of the visual processing stream where input from both eyes has come together, but where generalization for spatial localization and orientation has not yet occurred.
Areal and laminar organization of corticocortical projections in the rat somatosensory cortex
TLDR
Analysis of patterns of connectivity between the primary somatosensory cortex of the rat (SI) and surrounding cortical areas also implicated in the processing of somatoensory information finds points of reference in determining the relation between injection sites and the resultant patterns of label.

TLDR
The hypothesis that vernier breaks are detected ‘early’ during pattern recognition is supported by the fact that reaction times for the detection of verniers depend hardly at all on the number of stimuli presented simultaneously, indicating that deviation from straightness is an elementary feature for visual pattern recognition in humans that is detected at an early stage of pattern recognition.

TLDR
This work reports remarkable long-term learning in a simple texture discrimination task where learning is specific for retinal input and suggests that learning involves experience-dependent changes at a level of the visual system where monocularity and the retinotopic organization of thevisual input are still retained and where different orientations are processed separately.
Learning through maps: functional significance of topographic organization in primary sensory cortex.
TLDR
Recent behavioral and physiological studies suggest that, when animals or human subjects learn perceptual tasks, the neural modifications associated with the learning are distributed according to the spatial arrangement of the primary sensory cortical map.

TLDR
It is suggested that in two–dimensional translation invariance–as in three–dimensional rotation invariance—the human visual system is relying on memory–intensive rather than computation–intensive processes.
