    Bayesian analysis of retinotopic maps

    Noah C Benson, Jonathan Winawer
    A novel Bayesian method of modeling retinotopic maps is more accurate than traditional voxel-wise methods and can be used to automatically derive high-quality maps.

    A hierarchical, retinotopic proto-organization of the primate visual system at birth

    Michael J Arcaro, Margaret S Livingstone
    A retinotopic proto-organization present at birth provides the infrastructure for the subsequent development of visual cortex that commences at the onset of visual experience.

    Variability of visual field maps in human early extrastriate cortex challenges the canonical model of organization of V2 and V3

    Fernanda Lenita Ribeiro, Ashley York ... Alexander Puckett
    The representation of the retina in early visual cortex shows that human brains have diverse functional organizations, raising questions about developmental mechanisms for visual map formation and how reliably these can be described by average templates.

    An extended retinotopic map of mouse cortex

    Jun Zhuang, Lydia Ng ... Jack Waters
    An expanded map of mouse cortex reveals the expansion of retinotopic organization into barrel and retrosplenial cortices.

    Spatial readout of visual looming in the central brain of Drosophila

    Mai M Morimoto, Aljoscha Nern ... Michael B Reiser
    In the Drosophila central brain, synaptic connectivity extracts visual-spatial information from the axons of looming sensitive LC6 neurons that terminate in a glomerulus with minimal retinotopy.

    THINGS-data, a multimodal collection of large-scale datasets for investigating object representations in human brain and behavior

    Martin N Hebart, Oliver Contier ... Chris I Baker
    THINGS-data reflects three large-scale neuroimaging and behavioral datasets of object processing in humans, comprising densely sampled functional MRI and magnetoencephalographic recordings, as well as 4.70 million similarity judgments in response to thousands of photographic images for up to 1854 objects.
    1. Neuroscience

    Cortical magnification in human visual cortex parallels task performance around the visual field

    Noah C Benson, Eline R Kupers ... Jonathan Winawer
    In humans, the surface area of early visual cortex across polar angle is distributed in a pattern that correlates strongly with radial asymmetries in behavioral performance on visual tasks.
    1. Neuroscience

    Using an achiasmic human visual system to quantify the relationship between the fMRI BOLD signal and neural response

    Pinglei Bao, Christopher J Purington, Bosco S Tjan
    The lower-level retinotopic visual cortex of humans born without the optic chiasm comprises two independent neuronal populations and forms a versatile model for quantifying the relationship between the fMRI BOLD signal and neural response.
    1. Neuroscience

    Population receptive fields in nonhuman primates from whole-brain fMRI and large-scale neurophysiology in visual cortex

    P Christiaan Klink, Xing Chen ... Pieter R Roelfsema
    Within-species comparison of population receptive fields determined with fMRI and electrophysiology in nonhuman primates reveals the neuronal basis of blood-oxygen-level-dependent-based retinotopy.
    1. Neuroscience

    Contrast polarity-specific mapping improves efficiency of neuronal computation for collision detection

    Richard Burkett Dewell, Ying Zhu ... Fabrizio Gabbiani
    The processing of light and dark contrast information for detecting impending visual threats within grasshopper neurons reveals new mechanisms of information processing in the brain.
