    Adaptation of spontaneous activity in the developing visual cortex

    Marina E Wosniack, Jan H Kirchner ... Julijana Gjorgjieva
    To generate stable and robust connectivity refinements, the amplitude of spontaneous activity events in the developing visual cortex adapts to the recent history of cortical activation.

    Visual mode switching learned through repeated adaptation to color

    Yanjun Li, Katherine EM Tregillus ... Stephen A Engel
    The visual system can learn to rapidly adjust itself through experience, switching modes to stabilize vision perception and optimize perceptual processes.
    1. Neuroscience

    Stimulus relevance modulates contrast adaptation in visual cortex

    Andreas J Keller, Rachael Houlton ... Fritjof Helmchen
    Cortex dynamically regulates the flow of sensory information by suppressing responses of non-relevant stimuli through mechanisms of adaptation, while boosting sensory responses that are behaviorally important.

    The LIM protein complex establishes a retinal circuitry of visual adaptation by regulating Pax6 α-enhancer activity

    Yeha Kim, Soyeon Lim ... Jin Woo Kim
    Regulation of Pax6 expression through the α-enhancer fine-tunes amacrine cell subtype number, and consequently, the visual output of the retina.

    Divisive suppression explains high-precision firing and contrast adaptation in retinal ganglion cells

    Yuwei Cui, Yanbin V Wang ... Daniel A Butts
    The convergence of two visual pathways at the level of retinal bipolar cells accounts for key features of ganglion cell responses.
    1. Neuroscience

    Fine-scale computations for adaptive processing in the human brain

    Elisa Zamboni, Valentin G Kemper ... Zoe Kourtzi
    Laminar fMRI reveals that adaptive processing involves recurrent processing within visual cortex and top-down influences from posterior parietal cortex via feedback.
    1. Neuroscience

    Induced sensorimotor cortex plasticity remediates chronic treatment-resistant visual neglect

    Jacinta O'Shea, Patrice Revol ... Yves Rossetti
    Tonic disinhibition of left motor cortex during prism adaptation enhanced consolidation of sensorimotor and cognitive prism after effects, causing lasting clinical gains in three patient cases with chronic treatment-resistant visual neglect.
    1. Neuroscience

    Mechanisms underlying sharpening of visual response dynamics with familiarity

    Sukbin Lim
    Changes in neural response dynamics observed with visual learning provide a novel means to dissect synaptic plasticity and its interplay with slow negative feedback via firing rate adaptation.
    1. Neuroscience

    Contrary neuronal recalibration in different multisensory cortical areas

    Fu Zeng, Adam Zaidel, Aihua Chen
    Single-unit recordings from cortical neurons in behaving macaque monkeys expose differential aspects of multisensory plasticity across different multisensory areas during visual–vestibular recalibration.
    1. Neuroscience

    Predictably manipulating photoreceptor light responses to reveal their role in downstream visual responses

    Qiang Chen, Norianne T Ingram ... Fred Rieke
    Quantitative models for responses of rod and cone photoreceptors are developed that allow direct tests of the impact of the photoreceptors on responses of downstream visual neurons.
