    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.

    Dynamic representation of 3D auditory space in the midbrain of the free-flying echolocating bat

    Ninad B Kothari, Melville J Wohlgemuth, Cynthia F Moss
    Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.

    Astrocyte aquaporin mediates a tonic water efflux maintaining brain homeostasis

    Cuong Pham, Yuji Komaki ... Dongdong Li
    The water channel AQP4 contributes to a tonic water outflow from brain astrocytes, thereby modulating their volume dynamics and the ambient water homeostasis.

    Pharmacological rescue of impaired mitophagy in Parkinson’s disease-related LRRK2 G2019S knock-in mice

    Francois Singh, Alan R Prescott ... Ian G Ganley
    The most common Parkinson’s disease-associated mutation, LRRK2 G2019S, impairs mitophagy in clinically relevant cells within the mouse brain and this defect can be reversed using a novel LRRK2 inhibitor.

    Time-resolved single-cell sequencing identifies multiple waves of mRNA decay during the mitosis-to-G1 phase transition

    Lenno Krenning, Stijn Sonneveld, Marvin E Tanenbaum
    mRNA decay contributes to reshape the transcriptome as a parent cell divides into daughter cells.

    Parallel processing of quickly and slowly mobilized reserve vesicles in hippocampal synapses

    Juan Jose Rodriguez Gotor, Kashif Mahfooz ... John F Wesseling
    Reevaluation of reserve synaptic vesicle pools supports a new model of presynaptic function.

    A multi-hierarchical approach reveals d-serine as a hidden substrate of sodium-coupled monocarboxylate transporters

    Pattama Wiriyasermkul, Satomi Moriyama ... Shushi Nagamori
    An unbiased approach unveils a non-canonical substrate of the known transporters, highlighting the mechanism behind the use of D-serine as a kidney biomarker.

    Cardiac electrophysiological remodeling associated with enhanced arrhythmia susceptibility in a canine model of elite exercise

    Alexandra Polyák, Leila Topal ... András Varró
    Vigorous endurance training results in prolongation of cardiac repolarization and increased repolarization instability, mild ventricular fibrosis associated with decrease of the transient outward potassium current, and enhanced arrhythmia susceptibility in canine model.

    Residual force enhancement is affected more by quadriceps muscle length than stretch amplitude

    Patrick Bakenecker, Tobias Weingarten ... Brent Raiteri
    Increasing muscle length, rather than increasing stretch amplitude, contributes more to residual force enhancement during submaximal voluntary contractions of the human quadriceps.

    Pum2 and TDP-43 refine area-specific cytoarchitecture post-mitotically and modulate translation of Sox5, Bcl11b, and Rorb mRNAs in developing mouse neocortex

    Kawssar Harb, Melanie Richter ... Kent Duncan
    RNA-binding proteins use both translational activation and repression of key molecular determinants to post-mitotically sculpt the identity and connectivity of developing mouse neocortex in an area-specific manner.
