    How biological attention mechanisms improve task performance in a large-scale visual system model

    Grace W Lindsay, Kenneth D Miller
    Implementing neural changes associated with attention in a deep neural network causes performance changes that mimic those observed in humans and macaques.
    1. Neuroscience

    Distinct roles of forward and backward alpha-band waves in spatial visual attention

    Andrea Alamia, Lucie Terral ... Rufin VanRullen
    Covert visual attention modulates alpha-band traveling waves propagating from frontal to occipital regions in both hemispheres, yet it modulates waves propagating in the opposite direction (occipital to frontal) only in the presence of visual stimulation.
    1. Neuroscience

    Attentional amplification of neural codes for number independent of other quantities along the dorsal visual stream

    Elisa Castaldi, Manuela Piazza ... Evelyn Eger
    The representations of information concerning the number, size, density and surface of sets of objects in a visual image are separable along the occipito-parietal cortex and independently modulated by attention.
    1. Neuroscience

    Spatial sampling in human visual cortex is modulated by both spatial and feature-based attention

    Daniel Marten van Es, Jan Theeuwes, Tomas Knapen
    The sampling of visual space is not only warped by attention towards locations but also depends on attended features.
    1. Neuroscience

    Visual attention modulates the integration of goal-relevant evidence and not value

    Pradyumna Sepulveda, Marius Usher ... Benedetto De Martino
    Visual attention modulates the integration of the evidence that is most useful for achieving a goal in both perceptual and value-based decisions.
    1. Neuroscience

    Laminar microcircuitry of visual cortex producing attention-associated electric fields

    Jacob A Westerberg, Michelle S Schall ... Jeffrey D Schall
    Simultaneous sampling of electrical voltages outside the brain with neural signals in the cerebral cortex reveals how electrical currents in mosaics of cortical columns produce an electrical signal that can be measured noninvasively to assess the allocation of attention.
    1. Neuroscience

    The normalization model predicts responses in the human visual cortex during object-based attention

    Narges Doostani, Gholam-Ali Hossein-Zadeh, Maryam Vaziri-Pashkam
    A normalization model is shown to predict responses to multiple objects across changes in the attentional state in the visual cortex, providing evidence for the role of normalization as a fundamental operation in the human brain.
    1. Neuroscience

    Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

    Amélie Aussel, Ian C Fiebelkorn ... Benjamin Rafael Pittman-Polletta
    A biophysical cortical circuit model reveals how thalamic inputs mediate complex dynamics in the frontal eye fields and lateral intraparietal area, enabling rhythmic enhancements in visual sensitivity observed behaviorally.
    1. Neuroscience

    Visual attention is available at a task-relevant location rapidly after a saccade

    Tao Yao, Madhura Ketkar ... B Suresh Krishna
    Spatial attention and saccadic processing co-ordinate to ensure that attention is available at a task-relevant location soon after the beginning of each eye fixation.
    1. Neuroscience

    Cortical entrainment to hierarchical contextual rhythms recomposes dynamic attending in visual perception

    Peijun Yuan, Ruichen Hu ... Yi Jiang
    The human brain involuntarily exploits multiscale regularities in rhythmic contexts to recompose the dynamic profile of visual temporal attention.
