    Wavenumber-dependent transmission of subthreshold waves on electrical synapses network model of Caenorhabditis elegans

    Iksoo Chang, Taegon Chung, Sangyeol Kim
    The composition of nodes that effectively transmit sinusoidal waves in a model network resembling C. elegans' electrical synapses network changes according to the waves' wavenumber.

    Feed-forward recruitment of electrical synapses enhances synchronous spiking in the mouse cerebellar cortex

    Andreas Hoehne, Maureen H McFadden, David A DiGregorio
    Transient recruitment of electrical synapses mediates precisely timed excitation and inhibition to enhance synchronized control of cerebellar cortical output.

    Speed and segmentation control mechanisms characterized in rhythmically-active circuits created from spinal neurons produced from genetically-tagged embryonic stem cells

    Matthew J Sternfeld, Christopher A Hinckley ... Samuel L Pfaff
    Stem cell derived ventral-spinal cord excitatory neurons self-assemble into a rhythmically bursting neural network whose speed and intercellular coordination are both instructively modulated by cell-type specific interactions with inhibitory neurons.

    Spinal Shox2 interneuron interconnectivity related to function and development

    Ngoc T Ha, Kimberly J Dougherty
    Spinal Shox2 interneurons are strongly interconnected by gap junctional coupling in a function-specific manner, which provides a mechanism for synchronization of rhythm-generating neurons and may contribute to locomotor rhythmicity.

    A genetic basis for molecular asymmetry at vertebrate electrical synapses

    Adam C Miller, Alex C Whitebirch ... Cecilia B Moens
    Electrical synapses are neuronal, gap-junction-based connections found throughout the nervous system that, in the escape circuit of zebrafish, are composed of molecularly distinct pre- and postsynaptic junction forming proteins that are required for behavioral performance.

    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.

    Using subthreshold events to characterize the functional architecture of the electrically coupled inferior olive network

    Yaara Lefler, Oren Amsalem ... Yosef Yarom
    Non-synaptic electrical events recorded simultaneously from pairs of neurons in the inferior olive nucleus enables accurate estimation of the size and of the clustered organization of the electrically coupled network.

    Connectomic analysis of the Drosophila lateral neuron clock cells reveals the synaptic basis of functional pacemaker classes

    Orie T Shafer, Gabrielle J Gutierrez ... Maria de la Paz Fernandez
    The most influential clocks within the Drosophila circadian clock neuron network form the fewest synapses within the network, and neurons that do not themselves contain molecular clocks mediate connections between those that do, suggesting a key role in timekeeping.

    Modeling spinal locomotor circuits for movements in developing zebrafish

    Yann Roussel, Stephanie F Gaudreau ... Tuan V Bui
    Computational models of spinal locomotor circuits in developing zebrafish reveal how new movements can emerge during development through the integration of new spinal neurons and new connections.

    Network oscillation rules imposed by species-specific electrical coupling

    Stefanos Stagkourakis, Carolina Thörn Pérez ... Christian Broberger
    An unexpected species difference in electrical coupling of analogous neuroendocrine dopamine neurons in rats and mice reveals a role for gap junction connectivity as a band-pass filter for oscillation frequency in neural networks.
