Perceptual Learning Incepted by Decoded fMRI Neurofeedback Without Stimulus Presentation
TL;DR: It is suggested that early visual areas are so plastic that mere inductions of activity patterns are sufficient to cause visual perceptual learning (VPL).

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.

Visual experience induces long-term potentiation in the primary visual cortex.

TL;DR: It is demonstrated that LTP similarly enhances the amplitude of VEPs, but in a way that generalizes across multiple stimuli, spatial frequencies, and contrasts, and SRP is expressed by the same core mechanisms as LTP, providing a simple assay to assess the integrity of LTP in the intact nervous system.

Perceptual Learning Selectively Refines Orientation Representations in Early Visual Cortex
TL;DR: It is demonstrated that extensive training can lead to targeted functional reorganization of the human visual cortex, refining the cortical representation of behaviorally relevant information.
Journal ArticleDOI
Perceptual learning as improved probabilistic inference in early sensory areas
TL;DR: This work shows that it can capture both the neurophysiological and behavioral aspects of perceptual learning by altering only the feedforward connectivity in a recurrent network of spiking neurons so as to improve probabilistic inference in early visual areas.

Where practice makes perfect in texture discrimination: evidence for primary visual cortex plasticity
Avi Karni,Dov Sagi +1 more
TL;DR: 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.

Functional reorganization of primary somatosensory cortex in adult owl monkeys after behaviorally controlled tactile stimulation
TL;DR: These experiments demonstrate that functional cortical remodeling of the S1 koniocortical field, area 3b, results from behavioral manipulations in normal adult owl monkeys.
Journal ArticleDOI
Practising orientation identification improves orientation coding in V1 neurons
TL;DR: Improved long-term neuronal performance resulted from changes in the characteristics of orientation tuning of individual neurons, which induces a specific and efficient increase in neuronal sensitivity in V1 of monkeys for learning orientation identification.
