    Motor cortex activity across movement speeds is predicted by network-level strategies for generating muscle activity

    Shreya Saxena, Abigail A Russo ... Mark M Churchland
    While performing learned movements at different speeds, motor cortex population activity can be understood based on the need to generate muscle activity via smooth, well-behaved dynamics.

    Distinctive mechanisms of epilepsy-causing mutants discovered by measuring S4 movement in KCNQ2 channels

    Michaela A Edmond, Andy Hinojo-Perez ... Rene Barro-Soria
    Because voltage-gated KCNQ2 channels are central to physiological and pathophysiological events, understanding how disease-causing mutations in different channel regions disrupt function will help future development of mutation-specific antiepileptic therapies.

    Hyperreactivity to uncertainty is a key feature of subjective cognitive impairment

    Bahaaeddin Attaallah, Pierre Petitet ... Masud Husain
    Analysis of performance on a novel behavioural paradigm investigating active information gathering reveals that subjective cognitive impairment is associated with hyperreactivity to uncertainty and links this mechanism to the affective burden in the condition and heightened insular-hippocampal connectivity.

    Intrinsic excitability mechanisms of neuronal ensemble formation

    Tzitzitlini Alejandre-García, Samuel Kim ... Rafael Yuste
    Optogenetic and electrical stimulation of primary visual cortex neurons reveals synaptic and cell-intrinsic mechanisms that underlie neuronal ensemble formation.

    Chondroitin sulfate proteoglycan 4,6 sulfation regulates sympathetic nerve regeneration after myocardial infarction

    Matthew R Blake, Diana C Parrish ... Beth A Habecker
    4,6-Sulfation of chondroitin sulfate proteoglycans prevents sympathetic nerve regeneration into the infarct after myocardial ischemia/reperfusion, and reducing this sulfation promotes nerve regeneration and decreases arrhythmia susceptibility.

    Computational modeling of threat learning reveals links with anxiety and neuroanatomy in humans

    Rany Abend, Diana Burk ... Bruno B Averbeck
    Applying computational modeling to quantify threat learning processes uncovers how variations in these conserved learning processes relate to anxiety severity and the neuroanatomical substrates moderating these associations.

    Functional abnormalities in the cerebello-thalamic pathways in a mouse model of DYT25 dystonia

    Hind Baba Aïssa, Romain W Sala ... Daniela Popa
    In a mouse model of DYT25 dystonia with disruption of striatal neurotransmission by Gnal mutation, the cerebello-thalamic excitability is increased following symptom expression and θ-burst cerebellar stimulations during cholinergic-induced dystonia depress the cerebello-thalamic transmission and reduce the motor symptom severity.

    Cytosolic aspartate aminotransferase moonlights as a ribosome-binding modulator of Gcn2 activity during oxidative stress

    Robert A Crawford, Mark P Ashe ... Graham D Pavitt
    Using mass spectrometry to study protein composition of translating ribosomes under unstressed or stress conditions, aspartate aminotransferase 2 (Aat2) is identified as a metabolic enzyme with a moonlighting function in the yeast integrated stress-response pathway.

    Single-cell transcriptome reveals insights into the development and function of the zebrafish ovary

    Yulong Liu, Michelle E Kossack ... Bruce W Draper
    Single-cell transcriptomics of the zebrafish ovary identifies both major and minor cell types and provides a valuable resource for researchers interested in reproductive biology, stem cell biology, and aquatic toxicology.

    Nanoscale resolution of microbial fiber degradation in action

    Meltem Tatli, Sarah Moraïs ... Itzhak Mizrahi
    Phenotypic heterogeneity at the single-cell level of cellulosomal machinery biosynthesis suggests a division-of-labor strategy as revealed by the nanoscale mechanistic and ecological investigation of in situ structure and distribution of cellulosomes on bacteria while interacting with the cellulosic substrate.
