    A neuronal least-action principle for real-time learning in cortical circuits

    Walter Senn, Dominik Dold ... Mihai A Petrovici
    A principle from which the neuronal dynamics and synaptic plasticity in arbitrary network architectures can be inferred, so that output errors are online minimized while simultaneously processing sensory input streams.

    Functional brain reconfiguration during sustained pain

    Jae-Joong Lee, Sungwoo Lee ... Choong-Wan Woo
    Human neuroimaging with time-evolving network analysis reveals dynamic interactions among multiple functional brain networks in response to sustained pain.

    The actin-modulating protein synaptopodin mediates long-term survival of dendritic spines

    Kenrick Yap, Alexander Drakew ... Thomas Deller
    Long-term imaging of dentate granule cells reveals that the presence of synaptopodin within large spines, rather than their size, conveys long-term stability to large spines.

    Age-related differences in prefrontal glutamate are associated with increased working memory decay that gives the appearance of learning deficits

    Milena Rmus, Mingjian He ... Matthew R Nassar
    Apparent age-related differences in learning are best accounted for by rapid decay of information in working memory, which is associated with levels of prefrontal glutamate.

    The connectome of the adult Drosophila mushroom body provides insights into function

    Feng Li, Jack W Lindsey ... Gerald M Rubin
    Analysis of neuronal circuit architecture provides mechanistic insights into what an adult fly can learn, remember, and use to guide its behavior.

    NPAS4 in the medial prefrontal cortex mediates chronic social defeat stress-induced anhedonia-like behavior and reductions in excitatory synapses

    Brandon W Hughes, Benjamin M Siemsen ... Makoto Taniguchi
    Social defeat stress induces transcription factor Npas4 expression in the medial prefrontal cortex and its chronic stress-induced changes in excitatory synaptic transmission, reduction of dendritic spine density, and anhedonia-like behaviors.

    Plural molecular and cellular mechanisms of pore domain KCNQ2 encephalopathy

    Timothy J Abreo, Emma C Thompson ... Edward C Cooper
    A single amino acid change in a neuronal ion channel called KCNQ2 blocks ion flow, prevents protein localization on axons, and results in severe epilepsy and slowed neurological development.

    Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

    Amélie Aussel, Ian C Fiebelkorn ... Benjamin Rafael Pittman-Polletta
    A biophysical cortical circuit model reveals how thalamic inputs mediate complex dynamics in the frontal eye fields and lateral intraparietal area, enabling rhythmic enhancements in visual sensitivity observed behaviorally.

    The Na+/K+ pump dominates control of glycolysis in hippocampal dentate granule cells

    Dylan J Meyer, Carlos Manlio Díaz-García ... Gary Yellen
    Neuronal glycolysis to restore energy consumed by ion movements is activated by engagement of the Na+/K+ pump, either directly by Na+ influx or indirectly, when Ca2+ influx is converted to Na+ accumulation by Na+/Ca2+ exchange.
    1. Neuroscience

    Local cortical desynchronization and pupil-linked arousal differentially shape brain states for optimal sensory performance

    Leonhard Waschke, Sarah Tune, Jonas Obleser
    The momentary levels of local cortical desynchronization and pupil-linked arousal pose dissociable influences not only on the processing of sensory information but also on human perceptual performance.
