    Self-organization of modular network architecture by activity-dependent neuronal migration and outgrowth

    Samora Okujeni, Ulrich Egert
    Activity-dependent neurite outgrowth and neuronal migration interact to shape modular mesoscale network architecture by homeostatic self-organization.

    Self-organization of in vitro neuronal assemblies drives to complex network topology

    Priscila C Antonello, Thomas F Varley ... Jean Faber
    Effectively connected neurons self-organize forming networks with a small-world architecture composed of modules, with most likely few and nearby neurons, integrated by more topologically important and high firing rate neurons.

    Homeostatic regulation through strengthening of neuronal network-correlated synaptic inputs

    Samuel J Barnes, Georg B Keller, Tara Keck
    Following sensory deprivation in adult mice, homeostatic synaptic strengthening occurs in non-sensory network responsive synapses, but not in sensory responsive synapses, despite homeostatic increases to the global sensory-evoked responses.

    NetPyNE, a tool for data-driven multiscale modeling of brain circuits

    Salvador Dura-Bernal, Benjamin A Suter ... William W Lytton
    The NetPyNE software tool provides a framework to efficiently develop, simulate, optimize and analyze experimentally grounded neural models spanning the molecular, cellular and circuit scales.

    Synchronized excitability in a network enables generation of internal neuronal sequences

    Yingxue Wang, Zachary Roth, Eva Pastalkova
    Hippocampal sharp-wave sequences, which are considered the key phenomenon underlying consolidation of episodic memory, are preserved even after an animal’s memory is impaired.

    Structural and functional properties of a probabilistic model of neuronal connectivity in a simple locomotor network

    Andrea Ferrario, Robert Merrison-Hort ... Roman Borisyuk
    A new probabilistic model of connectivity reveals the structural and functional properties of the neural networks controlling locomotion in many individual tadpoles.

    Learning excitatory-inhibitory neuronal assemblies in recurrent networks

    Owen Mackwood, Laura B Naumann, Henning Sprekeler
    The synaptic structure in mouse V1 is explained by a synergy of homeostatic plasticity in incoming and outgoing synapses of inhibitory interneurons, establishing a stimulus-specific balance of excitation and inhibition.

    Interplay between population firing stability and single neuron dynamics in hippocampal networks

    Edden Slomowitz, Boaz Styr ... Inna Slutsky
    Neuronal networks balance flexibility with stability by allowing the firing rate of individual neurons within a network to vary over time, while ensuring that the average firing rate across the network remains constant.

    Granger causality analysis for calcium transients in neuronal networks, challenges and improvements

    Xiaowen Chen, Faustine Ginoux ... Claire Wyart
    A practical toolbox for application of Granger causality inference to calcium imaging data identifies strong driver neurons in the locus of the mesencephalic locomoter region in larval zebrafish.
