    Memory recall involves a transient break in excitatory-inhibitory balance

    Renée S Koolschijn, Anna Shpektor ... Helen C Barron
    Hippocampal activity during memory recall predicts a transient increase in the ratio between neocortical glutamate and GABA, thereby allowing otherwise dormant memories to be released.

    Propagated infra-slow intrinsic brain activity reorganizes across wake and slow wave sleep

    Anish Mitra, Abraham Z Snyder ... Marcus E Raichle
    Human fMRI experiments reveal differences in the propagation of spontaneous brain activity during sleep versus wakefulness.
    1. Neuroscience

    A prediction model of working memory across health and psychiatric disease using whole-brain functional connectivity

    Masahiro Yamashita, Yujiro Yoshihara ... Hiroshi Imamizu
    Human neuroimaging and machine learning reveals a generalizable relationship between brain connectivity and working memory ability across healthy populations and distinct psychiatric diagnoses.
    1. Neuroscience

    Dissociation of impulsive traits by subthalamic metabotropic glutamate receptor 4

    Lukasz Piszczek, Andreea Constantinescu ... Wulf Haubensak
    Metabotropic glutamate receptors modulate impulse control by the subthalamic nucleus, dissociating trait impulsivity from basal ganglia motor function.

    Infant brain regional cerebral blood flow increases supporting emergence of the default-mode network

    Qinlin Yu, Minhui Ouyang ... Hao Huang
    Unprecedented 4D spatiotemporal infant regional cerebral blood flow framework and region-specific physiology–function coupling across infancy were elucidated, highlighting strong physiology–function coupling specifically at the default-mode network to meet extraneuronal metabolic demand for network emergence.

    Toward a more informative representation of the fetal–neonatal brain connectome using variational autoencoder

    Jung-Hoon Kim, Josepheen De Asis-Cruz ... Catherine Limperopoulos
    A nonlinear deep generative model can represent fetal–neonatal resting-state functional magnetic resonance imaging better than conventional linear models.
    1. Neuroscience

    Convergence of cortical types and functional motifs in the human mesiotemporal lobe

    Casey Paquola, Oualid Benkarim ... Boris C Bernhardt
    A novel model of the human mesiotemporal lobe suggests that its broad roles in cognition can be explained by how its cytoarchitecture and form relate to large-scale functional motifs.
    1. Neuroscience

    Decoding the brain state-dependent relationship between pupil dynamics and resting state fMRI signal fluctuation

    Filip Sobczak, Patricia Pais-Roldán ... Xin Yu
    The variability of the pupil–fMRI relationship was characterized through a combination of clustering and prediction methods, which revealed brain state-specific subcortical and neuromodulatory activation patterns reflected in pupil dynamics.
    1. Neuroscience

    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.
    1. Neuroscience

    Attention network modulation via tRNS correlates with attention gain

    Federica Contò, Grace Edwards ... Lorella Battelli
    Parietal noninvasive brain stimulation during perceptual training causes a dramatic increase in learning that correlates with network-wide changes in functional connectivity, demonstrating the stimulation-induced physiological mechanisms leading to cognitive benefits.
