    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.

    T2N as a new tool for robust electrophysiological modeling demonstrated for mature and adult-born dentate granule cells

    Marcel Beining, Lucas Alberto Mongiat ... Peter Jedlicka
    T2N, a novel interface between Matlab, TREES toolbox and NEURON, was used to generate compartmental models that reproduce the electrophysiology of dentate granule cells over a multitude of species, experimental conditions and developmental stages.

    Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

    Daniel Šmít, Coralie Fouquet ... Alain Trembleau
    Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.

    Base editing of Ptbp1 in neurons alleviates symptoms in a mouse model of Parkinson’s disease

    Desiree Böck, Maria Wilhelm ... Gerald Schwank
    Downregulation of PTBP1 in neurons, but not astrocytes, alleviates motor symptoms in a Parkinson’s disease mouse model by inducing dopaminergic marker expression in striatal neurons and increasing striatal dopamine levels.

    A kinematic synergy for terrestrial locomotion shared by mammals and birds

    Giovanna Catavitello, Yury Ivanenko, Francesco Lacquaniti
    General principles of the limb segment control for terrestrial locomotion have emerged in evolution and highlight the existence of the laws of biological motion that apply to various animal species.

    Two forms of asynchronous release with distinctive spatiotemporal dynamics in central synapses

    Gerardo Malagon, Jongyun Myeong, Vitaly A Klyachko
    Asynchronous release is not uniform, but comprises two subpopulations of events, one occurring inside the active zone and another occurring ectopically, which are characterized by distinctive spatiotemporal dynamics in hippocampal synapses.

    A neurotrophin functioning with a Toll regulates structural plasticity in a dopaminergic circuit

    Jun Sun, Francisca Rojo-Cortes ... Alicia Hidalgo
    A novel molecular mechanism linking a neurotrophin with a Toll-family and kinase-less Trk-like receptors provides a direct link from molecules to structural circuit plasticity and modification of behaviour.

    Regulation of two motor patterns enables the gradual adjustment of locomotion strategy in Caenorhabditis elegans

    Ingrid Hums, Julia Riedl ... Manuel Zimmer
    Peptidergic neurons regulate undulation and turning movements to enable Caenorhabditis elegans to gradually adjust its locomotion strategy from dispersal to local search.

    Effects of clozapine-N-oxide and compound 21 on sleep in laboratory mice

    Janine Traut, Jose Prius Mengual ... Lukas B Krone
    The two most commonly used chemogenetic actuators, clozapine-N-oxide and compound 21, similarly modulate sleep in wild-type laboratory mice indicating that even designer drugs which do not convert to clozapine can elicit behavioural effects and require adequate controls.

    MicroRNA-218 instructs proper assembly of hippocampal networks

    Seth R Taylor, Mariko Kobayashi ... Giordano Lippi
    MicroRNA-218 is required in both excitatory and inhibitory neurons of the developing hippocampus to regulate intrinsic and network excitability.
