We report that preexisting individual differences in the cortical thickness of brain areas involved in a perceptual learning task predict the subsequent perceptual learning rate. Participants trained in a motion-discrimination task involving visual search for a "V"-shaped target motion trajectory among inverted "V"-shaped distractor trajectories. Motion-sensitive area MT+ (V5) was functionally identified as critical to the task: after 3 weeks of training, activity increased in MT+ during task…

Long Time No See: Enduring Behavioral and Neuronal Changes in Perceptual Learning of Motion Trajectories 3 Years After Training
TLDR
Long-term stability of changes in behavior and brain activity following perceptual learning of conjunctions of simple motion features is reported on, suggesting that training-induced changes in stimulus representation are specific to trained stimulus identities.
Neural correlates of context‐dependent feature conjunction learning in visual search tasks
TLDR
It is shown that feature conjunction learning in visual search leads to bottom‐up changes in stimulus processing, and that the acquired change in target‐evoked activity is contextually dependent on the presence of distractors, suggesting that search array Gestalts are learned.
Convergence Along the Visual Hierarchy Is Altered in Posterior Cortical Atrophy
TLDR
Atrophy in one part of the visual system can affect other areas within the network through complex intervisual area interactions, resulting in modulation of population receptive field properties and an ensemble of visuocognitive function impairments.
Individual differences in frontoparietal plasticity in humans
TLDR
This work investigated the plasticity of the frontoparietal system by asking whether VTA resting-state functional connectivity and myelin map values predicted learning after short-term training on the adaptive n-back, and found that stronger baseline connectivity between VTA and lateral prefrontal cortex predicted greater improvements in accuracy.
Cortical Thickness of Functionally Defined Visual Areas in Schizophrenia and Bipolar Disorder
TLDR
The thickness of each visual region of interest was significantly correlated with performance on a visual object masking task, but only in schizophrenia patients, suggesting an anatomical substrate for visual processing abnormalities that have been found with both neural and behavioral measures in schizophrenia and other severe mental illnesses.
Learning efficient visual search for stimuli containing diagnostic spatial configurations and color-shape conjunctions
TLDR
It is shown that both targets and distractors are learned, and that reversing learned target and distractor identities impairs performance, which suggests conjunction learning involving such stimuli might be an emergent phenomenon that reflects multiple different learning processes.

Activations in Visual and Attention-Related Areas Predict and Correlate with the Degree of Perceptual Learning
TLDR
It is speculated that sharpened tuning of neuronal representations may cause reduced activation in visual cortex during perceptual learning and that attention may facilitate this process through an interaction of attention-related and visual cortical regions.
Neural correlates of perceptual learning in a sensory-motor, but not a sensory, cortical area
TLDR
Perceptual learning does not appear to involve improvements in how sensory information is represented in the brain, but rather how the sensory representation is interpreted to form the decision that guides behavior.
Neural correlates of perceptual learning: A functional MRI study of visual texture discrimination
TLDR
Using functional magnetic resonance imaging in humans, neural activity is measured 24 h after a single session of intensive monocular training on visual texture discrimination to provide a direct demonstration of learning-dependent reorganization at early processing stages in the visual cortex of adult humans.
Learning to See Biological Motion: Brain Activity Parallels Behavior
TLDR
Individuals improve with practice on a variety of perceptual tasks, presumably reflecting plasticity in underlying neural mechanisms, and changes in activation within the posterior superior temporal sulcus and the fusiform face area, brain areas involved in perception of biological events are examined.
Decoding Reveals Plasticity in V3A as a Result of Motion Perceptual Learning
TLDR
It is concluded that VPL of a global motion detection task involves plasticity in a specific visual cortical area using pattern classification analysis on functional magnetic resonance imaging signals.

TLDR
When participants were retested on the original task after nine months without further training, the acquired changes in behavior and brain activity were still present, showing that this can be an enduring form of learning and neural reorganization.
