    Mapping quantal touch using 7 Tesla functional magnetic resonance imaging and single-unit intraneural microstimulation

    Rosa Maria Sanchez Panchuelo, Rochelle Ackerley ... Francis McGlone
    The combination of intraneural microstimulation and 7T fMRI makes it possible to bridge the gap between first-order mechanoreceptive afferent input codes and their spatial, dynamic and perceptual representations in human cortex.

    Multi-contrast anatomical subcortical structures parcellation

    Pierre-Louis Bazin, Anneke Alkemade ... Birte U Forstmann
    An open-source software tool enables the anatomical parcellation of an unprecedented number of subcortical structures in magnetic resonance images of the human brain, automatically and in individual subjects.

    Functional subregions of the human entorhinal cortex

    Anne Maass, David Berron ... Emrah Düzel
    By employing high-field fMRI to measure connectivity with the hippocampus and adjacent parahippocampal structures within the medial temporal lobe, it is shown that the entorhinal cortex can be divided into anterior-lateral and posterior-medial subregions.

    Perceptually relevant remapping of human somatotopy in 24 hours

    James Kolasinski, Tamar R Makin ... Heidi Johansen-Berg
    A combination of 7 tesla fMRI and psychophysics revealed the reorganisation of the human somatosensory cortex and changes in tactile perceptual abilities after just 24 hours of altered hand use.

    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.

    Resting state functional connectivity in the human spinal cord

    Robert L Barry, Seth A Smith ... John C Gore
    Resting state spinal fMRI will be useful in studies of normal spinal cord function and central nervous system disorders.
    1. Neuroscience

    Functional topography of the human entorhinal cortex

    Tobias Navarro Schröder, Koen V Haak ... Christian F Doeller
    By employing high-field fMRI and taking advantage of well-known global connectivity fingerprints and sensitivity to spatial and non-spatial information, it is shown that the entorhinal cortex is primarily divided into anterior and posterior subregions.

    Spatiotemporal neural dynamics of object recognition under uncertainty in humans

    Yuan-hao Wu, Ella Podvalny, Biyu J He
    Combining 7 Tesla fMRI and MEG data collected during a challenging visual recognition task revealed distinct neural representational formats in ventral visual and frontoparietal regions, and the emergence of recognition-related signals prior to category-related information.
    1. Neuroscience

    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.
    1. Neuroscience

    Conditioned respiratory threat in the subdivisions of the human periaqueductal gray

    Olivia K Faull, Mark Jenkinson ... Kyle TS Pattinson
    High-resolution imaging shows that the different columns of the human periaqueductal gray play differential roles in the response to a respiratory threat.
