    Mapping the human subcortical auditory system using histology, postmortem MRI and in vivo MRI at 7T

    Kevin R Sitek, Omer Faruk Gulban ... Federico De Martino
    MRI methods are promising techniques for investigating the human subcortical auditory system, and these publicly available data, atlases, and tools make researching human audition simpler and more reliable.
    1. Neuroscience

    Dynamic behavior of the locus coeruleus during arousal-related memory processing in a multi-modal 7T fMRI paradigm

    Heidi IL Jacobs, Nikos Priovoulos ... Kâmil Uludağ
    By combining ultra-high-field imaging with physiological and saliva measures it is established that interactions between locus coeruleus, hippocampus and amygdala vary along emotional memory stages, putatively reflecting distinct cognitive states.
    1. Neuroscience

    Improving a probabilistic cytoarchitectonic atlas of auditory cortex using a novel method for inter-individual alignment

    Omer Faruk Gulban, Rainer Goebel ... Federico de Martino
    Inter-individual human brain alignment that uses macro-anatomical priors in addition to cortical curvature improves micro-anatomical correspondence between auditory areas.
    1. Neuroscience

    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.

    High-resolution quantitative and functional MRI indicate lower myelination of thin and thick stripes in human secondary visual cortex

    Daniel Haenelt, Robert Trampel ... Nikolaus Weiskopf
    In vivo quantitative magnetic resonance imaging at ultra-high magnetic field reveals systematic differences of relaxation parameters (R1) within the human secondary visual cortex at the level of the thin-thick-pale stripes system, which points toward higher cortical myelination of pale stripes.
    1. Neuroscience

    The cerebellum is involved in processing of predictions and prediction errors in a fear conditioning paradigm

    Thomas Michael Ernst, Anna Evelina Brol ... Dagmar Timmann
    Pronounced cerebellar activation during unexpected omission of a potentially harmful event suggests that the cerebellum has to be added to the neural network processing prediction errors underlying emotional associative learning.
    1. Neuroscience

    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

    Perception is associated with the brain’s metabolic response to sensory stimulation

    Mauro DiNuzzo, Silvia Mangia ... Federico Giove
    Perceived and unperceived visual stimuli that are contrast matched to produce similar BOLD responses in V1 elicit clearly distinct changes in the neurochemical profile, implying a perception-related dissociation between neurometabolic and neurovascular response.
    1. Neuroscience

    Age-related differences in the functional topography of the locus coeruleus and their implications for cognitive and affective functions

    Dániel Veréb, Mite Mijalkov ... Joana B Pereira
    A gradient-based approach is employed to characterize the organization of functional connectivity in the human locus coeruleus, revealing age-related differences and associations with cognitive and affective functions independently from age.
    1. Neuroscience

    Regional response to light illuminance across the human hypothalamus

    Islay Campbell, Roya Sharifpour ... Gilles Vandewalle
    Distinct local dynamics of different hypothalamus areas were detected in response to changing illuminance and could contribute to light’s impact on cognition.
