    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.

    Instantaneous antidepressant effect of lateral habenula deep brain stimulation in rats studied with functional MRI

    Gen Li, Binshi Bo ... Xiaojie Duan
    Electrical stimulation at the lateral habenula causes an instantaneous remission of depressive symptoms in two rat models, with more medial stimulation sites exhibiting greater antidepressant effects than more lateral stimulation sites, as revealed by functional MRI studies.

    Anatomical and functional connectivity support the existence of a salience network node within the caudal ventrolateral prefrontal cortex

    Lucas R Trambaiolli, Xiaolong Peng ... Suzanne N Haber
    The primate caudal area 47/12 is anatomically and functionally connected with the main nodes of the salience network, supporting the role of the ventrolateral prefrontal cortex in all major attention networks.

    Functional connectivity in human auditory networks and the origins of variation in the transmission of musical systems

    Massimo Lumaca, Boris Kleber ... Giosue Baggio
    Resting-state functional connectivity between core regions of fronto-temporal auditory networks can distinguish music transmitters from innovators.

    Anatomical and functional organization of the human substantia nigra and its connections

    Yu Zhang, Kevin Michel-Herve Larcher ... Alain Dagher
    The human substantia nigra can be parcellated into three subdivisions that subserve emotional, cognitive and somatomotor function.

    Atypical intrinsic neural timescale in autism

    Takamitsu Watanabe, Geraint Rees, Naoki Masuda
    Atypical intrinsic neural timescales in the sensory cortex and caudate were associated with local grey matter volume, and linked with the severity of autism.

    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.

    Spatial signatures of anesthesia-induced burst-suppression differ between primates and rodents

    Nikoloz Sirmpilatze, Judith Mylius ... Susann Boretius
    Functional imaging (fMRI) across four mammalian species maps the brain areas engaging in burst-suppression activity during anesthesia, and uncovers differences between primates and rodents.

    What happens to the inhibitory control functions of the right inferior frontal cortex when this area is dominant for language?

    Esteban Villar-Rodríguez, Cristina Cano-Melle ... César Avila
    A complementary relationship exists between the hemispheric lateralization of inhibitory control (typically right) and speech (typically left), as observed in typically and atypically lateralized left-handed individuals.

    Multimodal brain age estimates relate to Alzheimer disease biomarkers and cognition in early stages: a cross-sectional observational study

    Peter R Millar, Brian A Gordon ... Beau M Ances
    Machine learning-based models of brain age using distinct MRI modalities (structural MRI and functional connectivity) capture complementary signals related to healthy age differences and capture unique patterns related to Alzheimer disease, including stages of disease progression, biomarkers, and cognition.
