TLDR
Using a clever stimulus that separates local from global motion features, the authors of a new paper show that perceptual learning occurs at low cortical levels when the motion is irrelevant to the observer's task, whereas higher-level learning of the same stimulus requires attention.Abstract:

Perceptual learning: toward a comprehensive theory.
Takeo Watanabe,Yuka Sasaki +1 more
TL;DR: A dual plasticity model is proposed in which feature-based plasticity is a change in a representation of the learned feature, and task-based Plasticity isA change in processing of the trained task.

TL;DR: The state of the science for an emerging technology, real time functional magnetic resonance imaging (rtfMRI) neurofeedback, in clinical neurotherapeutics is described and the overall goal is for rtfMRI to advance personalized assessment and intervention approaches to enhance resilience and reduce morbidity by correcting maladaptive patterns of brain function in those with brain disorders.

TL;DR: Known mechanisms of how brain states mediate and modulate learning by their characteristic rhythmic signatures are reviewed and new avenues for utilizing neuronal learning mechanisms in developing tools and therapies are illuminated.

Vision restoration after brain and retina damage: the "residual vision activation theory".
TL;DR: The residual vision activation theory as discussed by the authors proposes that residual structures can be reactivated by engaging them in repetitive stimulation by different means: (i) visual experience, (ii) visual training, or (iii) noninvasive electrical brain current stimulation.
Journal ArticleDOI
Making perceptual learning practical to improve visual functions.
TL;DR: It is shown that the transfer of functions indicates that the specificity of improvement in the trained task can be generalized by repetitive practice of target detection, covering a sufficient range of spatial frequencies and orientations, leading to an improvement in unrelated visual functions.

Somatosensory cortical map changes following digit amputation in adult monkeys
Michael M. Merzenich,R. J. Nelson,Michael P. Stryker,Max S. Cynader,Axel Schoppmann,John M. Zook +5 more
TL;DR: The cortical representations of the hand in area 3b in adult owl monkeys were defined with use of microelectrode mapping techniques 2–8 months after surgical amputation of digit 3, or of both digits 2 and 3.

Binocular interaction in striate cortex of kittens reared with artificial squint.
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: The object of the present study was to influence cortical connections by some means less drastic than covering one or both eyes, and produced a divergent strabismus by cutting one of the extraocular muscles in each of four newborn kittens.

Receptive field dynamics in adult primary visual cortex
TL;DR: The results indicate that the topographic reorganization within the cortex was largely due to synaptic changes intrinsic to the cortex, perhaps through the plexus of long-range horizontal connections.

Task difficulty and the specificity of perceptual learning.
Merav Ahissar,Shaul Hochstein +1 more
TL;DR: In this paper, the authors show that the degree of specificity depends on the difficulty of the training conditions, and that the pattern of specificities maps onto the patterns of receptive field selectivities along the visual pathway.

TL;DR: It is shown here that the degree of specificity depends on the difficulty of the training conditions, and it is found that the pattern of specificities maps onto the patterns of receptive field selectivities along the visual pathway.
