    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.

    Visual field map clusters in human frontoparietal cortex

    Wayne E Mackey, Jonathan Winawer, Clayton E Curtis
    Topographic maps of space in frontal and parietal cortex are organized into clusters, similar to visual cortex, where multiple maps of polar angle share a confluent fovea.

    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.

    Internally generated time in the rodent hippocampus is logarithmically compressed

    Rui Cao, John H Bladon ... Marc W Howard
    Receptive fields for time in the hippocampus, like receptive fields for retinal space and receptive fields for numerosity, obey the Weber-Fechner law.

    Spatially displaced excitation contributes to the encoding of interrupted motion by a retinal direction-selective circuit

    Jennifer Ding, Albert Chen ... Wei Wei
    The direction-selective circuit in the retina adjusts the contributions of excitatory and inhibitory mechanisms under different stimulus conditions to generate context-dependent neural representations of visual features.

    Robust cone-mediated signaling persists late into rod photoreceptor degeneration

    Miranda L Scalabrino, Mishek Thapa ... Greg D Field
    The retina compensates for rod death and deteriorating cones to retain high-fidelity visual signaling to the brain.
    1. Neuroscience

    A neural-level model of spatial memory and imagery

    Andrej Bicanski, Neil Burgess
    The BB model explains spatial cognition in terms of interactions between specific neuronal populations, providing a common computational framework for the human neuropsychological and in vivo animal electrophysiological literatures.

    Inference of nonlinear receptive field subunits with spike-triggered clustering

    Nishal P Shah, Nora Brackbill ... EJ Chichilnisky
    Nonlinear receptive field subunits in retinal ganglion cells are isolated and characterized by clustering spike-triggered stimuli, and validated on population responses to naturalistic and novel closed loop stimuli.

    Local processing in neurites of VGluT3-expressing amacrine cells differentially organizes visual information

    Jen-Chun Hsiang, Keith P Johnson ... Daniel Kerschensteiner
    Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.
