    Columnar processing of border ownership in primate visual cortex

    Tom P Franken, John H Reynolds
    The assignment of borders to foreground objects occurs in cortical columns in primate visual cortex, and first in deep layers, suggesting a central role for feedback.

    Phylogenetic variation in cortical layer II immature neuron reservoir of mammals

    Chiara La Rosa, Francesca Cavallo ... Luca Bonfanti
    The higher amount of cortical immature neurons in brains with expanded neocortices may represent a reservoir of young cells for mammals with reduced neurogenesis.

    Lamina-specific cortical dynamics in human visual and sensorimotor cortices

    James J Bonaiuto, Sofie S Meyer ... Sven Bestmann
    Cortical oscillations in human MEG are lamina-specific, with low-frequency activity predominating in deep, and high-frequency activity in more superficial layers of sensory and motor cortices.

    Double-μPeriscope, a tool for multilayer optical recordings, optogenetic stimulations or both

    Mototaka Suzuki, Jaan Aru, Matthew E Larkum
    Interactions between near but distinct (<1 mm) structures such as cortical layers in the rodent brain can be studied by a new micro-optical tool that is low-cost and capable of multilayer optical recordings, optogenetic stimulations, or both.

    Sparse recurrent excitatory connectivity in the microcircuit of the adult mouse and human cortex

    Stephanie C Seeman, Luke Campagnola ... Tim Jarsky
    A high-throughput pipeline for the characterization of cortical connectivity in mouse and human cortex.

    Thalamocortical axons control the cytoarchitecture of neocortical layers by area-specific supply of VGF

    Haruka Sato, Jun Hatakeyama ... Kenji Shimamura
    VGF was identified as a factor secreted from thalamocortical axons essential for the cytoarchitectonic features of neocortical layer 4 in the sensory areas in mice.

    Temporal transcriptomic dynamics in developing macaque neocortex

    Longjiang Xu, Zan Yuan ... Xiaozhong Peng
    A useful single-cell resource provides the prenatal macaque different cell types’ gene expression profiles in the parietal cerebral cortex lobe.

    Rate and oscillatory switching dynamics of a multilayer visual microcircuit model

    Gerald Hahn, Arvind Kumar ... Gustavo Deco
    A computer model of the mouse visual cortex shows that local brain circuits are organized as switches whose states are coded as neuronal oscillations with different frequencies.

    Spike-phase coupling patterns reveal laminar identity in primate cortex

    Zachary W Davis, Nicholas M Dotson ... John H Reynolds
    By examining the relationship between spike timing and the phase of the LFP across cortical layers, researchers can use a stereotyped phase-coupling pattern as a diagnostic marker for electrode depth when other methods of electrode placement are ambiguous.

    Dissociable laminar profiles of concurrent bottom-up and top-down modulation in the human visual cortex

    Samuel JD Lawrence, David G Norris, Floris P de Lange
    Neural activity in the visual system is increased in different layers of the neocortex for bottom-up and top-down modulations.
