    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.

    A connectome of the Drosophila central complex reveals network motifs suitable for flexible navigation and context-dependent action selection

    Brad K Hulse, Hannah Haberkern ... Vivek Jayaraman
    An analysis of the first complete synaptic resolution connectome of Drosophila's navigation circuit uncovers neural network motifs supporting broadly relevant sensorimotor computations.
    1. Neuroscience

    Efficient value synthesis in the orbitofrontal cortex explains how loss aversion adapts to the ranges of gain and loss prospects

    Jules Brochard, Jean Daunizeau
    Computational modeling shows how neural mechanisms for mitigating biological constraints (such as neurons’ limited firing range) may eventually result in complex though predictable irrational behavior.

    Mouse embryonic stem cells can differentiate via multiple paths to the same state

    James Alexander Briggs, Victor C Li ... Marc W Kirschner
    Single cell RNA sequencing reveals that mouse embryonic stem cells can be differentiated into the same terminal motor neuron state via distinct differentiation paths, one of which includes a surprising intermediate state not found in embryos.

    Dendritic nonlinearities are tuned for efficient spike-based computations in cortical circuits

    Balázs B Ujfalussy, Judit K Makara ... Máté Lengyel
    Dendrites combine the inputs that they receive from other neurons using calculations that have been optimized for those particular input patterns.

    TWIST1 and chromatin regulatory proteins interact to guide neural crest cell differentiation

    Xiaochen Fan, V Pragathi Masamsetti ... Patrick PL Tam
    Network propagation connects TWIST1 with epigenetic regulators CHD7, CHD8, and WHSC1, which collectively promote the bias toward neural crest while suppressing neural stem cell programmes, and subsequently enhance ectomesenchyme potential.

    Multiple neuronal networks coordinate Hydra mechanosensory behavior

    Krishna N Badhiwala, Abby S Primack ... Jacob T Robinson
    Despite lacking traditional ganglia or centralization, the Hydra nervous system computes sensorimotor responses via localized neuron ensembles.

    A chemical probe of CARM1 alters epigenetic plasticity against breast cancer cell invasion

    Xiao-Chuan Cai, Tuo Zhang ... Minkui Luo
    A chemical probe was characterized for potency, selectivity, and ability to alter CARM1-dependent epigenetic plasticity against cancer cell invasion.

    A human ESC-based screen identifies a role for the translated lncRNA LINC00261 in pancreatic endocrine differentiation

    Bjoern Gaertner, Sebastiaan van Heesch ... Maike Sander
    Ribosome profiling and loss-of-function during human ESC pancreatic differentiation reveal abundant lncRNA translation and an essential role for translated LINC00261 in beta cell differentiation, likely through a trans-regulatory, microprotein-independent mechanism.

    Cis-regulatory basis of sister cell type divergence in the vertebrate retina

    Daniel P Murphy, Andrew EO Hughes ... Joseph C Corbo
    While photoreceptor and bipolar cells exhibit very similar cis-regulatory grammars, subtle differences in homeodomain motif enrichment represent a key distinction driving the divergence in their transcriptomes.
