    The organizational principles of de-differentiated topographic maps in somatosensory cortex

    Peng Liu, Anastasia Chrysidou ... Esther Kuehn
    SI topographic finger maps of older adults show signs of cortical aging but do not show classical hallmarks of cortical de-differentiation.

    High-resolution and high-accuracy topographic and transcriptional maps of the nucleosome barrier

    Zhijie Chen, Ronen Gabizon ... Carlos Bustamante
    Direct observation of RNA Polymerase II transcription through a single nucleosome at near basepair resolution suggests a mechanism for selective control of gene expression.

    A molecular mechanism for the topographic alignment of convergent neural maps

    Elise Savier, Stephen J Eglen ... Michael Reber
    Retinal ephrin-As gradients provide positional information, through retino-collicular map in the superior colliculus, for topographic alignment of cortico-collicular projections.

    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.

    Ephrin-A/EphA specific co-adaptation as a novel mechanism in topographic axon guidance

    Felix Fiederling, Markus Weschenfelder ... Franco Weth
    A distinctive novel mechanism of ephrin-A/EphA signaling modulation in retinal growth cones ensures concurrent quantitative accuracy and adaptability of topographic hardwiring.

    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.

    Complex pattern of facial remapping in somatosensory cortex following congenital but not acquired hand loss

    Victoria Root, Dollyane Muret ... Tamar R Makin
    Both hand and face representations remain relatively stable after arm amputation in adulthood, with no link to phantom limb pain, whereas pre-natal limb loss triggers complex patterns of remapping that do not relate to cortical topography.

    Mapping the functional connectivity of ecosystem services supply across a regional landscape

    Rachel D Field, Lael Parrott
    Mapping functional relationships between multiple ecosystem services (ES) reveals previously unidentified areas of high ES value, which suggests that the spatial focus of planning for optimal ES provisioning may shift when relationships between several ES are considered.

    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.
    1. Neuroscience

    Adaptation of spontaneous activity in the developing visual cortex

    Marina E Wosniack, Jan H Kirchner ... Julijana Gjorgjieva
    To generate stable and robust connectivity refinements, the amplitude of spontaneous activity events in the developing visual cortex adapts to the recent history of cortical activation.
