    Spatial frequency representation in V2 and V4 of macaque monkey

    Ying Zhang, Kenneth E Schriver ... Anna Wang Roe
    V2 and V4 contain orthogonal maps of orientation and spatial frequency, which indicates a fundamental principle of functional mapping across the cortical surface that ensures and optimizes the complete representation of all combinations across two coding dimensions.

    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.

    Thalamus and claustrum control parallel layer 1 circuits in retrosplenial cortex

    Ellen KW Brennan, Izabela Jedrasiak-Cape ... Omar J Ahmed
    Parallel input streams to layer 1 identify a computationally distinct principal neuronal subtype ideally positioned to support spatial orientation computations in the granular retrosplenial cortex.

    Representational untangling by the firing rate nonlinearity in V1 simple cells

    Merse E Gáspár, Pierre-Olivier Polack ... Gergő Orbán
    Firing rate nonlinearity recovers linear decodability of orientation information from simple cells of the primary visual cortex under uncertainty of nuisance parameters phase and spatial frequency.

    Precise and stable edge orientation signaling by human first-order tactile neurons

    Vaishnavi Sukumar, Roland S Johansson, J Andrew Pruszynski
    Individual human first-order tactile neurons, those that innervate the mechanoreceptors in the skin, can signal information about edge orientation differences at the limit of what people can feel and across a broad range of speeds relevant for real-world hand use.

    Conditioning sharpens the spatial representation of rewarded stimuli in mouse primary visual cortex

    Pieter M Goltstein, Guido T Meijer, Cyriel MA Pennartz
    Stimulus-reward learning sharpens the local representation of the visual space while leaving the overall retinotopic map intact.

    From behavior to circuit modeling of light-seeking navigation in zebrafish larvae

    Sophia Karpenko, Sebastien Wolf ... Georges Debrégeas
    Light-seeking strategies in Zebrafish larvae are dissected using a virtual-reality assay, and these data are used to establish minimal stochastic and neural-circuits models that quantitatively capture this behavior.

    Sensory experience modifies feature map relationships in visual cortex

    Shaun L Cloherty, Nicholas J Hughes ... Michael R Ibbotson
    A new form of brain plasticity extends the known limits for how much early sensory input can alter the brain.

    A stochastic neuronal model predicts random search behaviors at multiple spatial scales in C. elegans

    William M Roberts, Steven B Augustine ... Shawn R Lockery
    A stochastic model of locomotory control in C. elegans based on an extensive new set of tracking data can explain and predict effects of ablations and mutations on behavior.

    Fast and accurate edge orientation processing during object manipulation

    J Andrew Pruszynski, J Randall Flanagan, Roland S Johansson
    Tactile edge orientation processing during object manipulation is many times better than previously thought based on perceptual studies.
