    Organelle calcium-derived voltage oscillations in pacemaker neurons drive the motor program for food-seeking behavior in Aplysia

    Alexis Bédécarrats, Laura Puygrenier ... Romuald Nargeot
    An atypical neuronal pacemaker mechanism triggers feeding motor pattern in Aplysia..

    Development of pacemaker properties and rhythmogenic mechanisms in the mouse embryonic respiratory network

    Marc Chevalier, Natalia Toporikova ... Muriel Thoby-Brisson
    Pacemaker neurons are present in the preBötC circuitry of mouse embryos and their role in driving respiratory network activity changes during the critical period immediately before birth.

    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.
    1. Neuroscience

    Insights into the dynamic control of breathing revealed through cell-type-specific responses to substance P

    Nathan A Baertsch, Jan-Marino Ramirez
    The neuromodulator substance P enhances mechanisms of recurrent excitation between breaths to control breathing frequency and stability.

    TRPC3 and NALCN channels drive pacemaking in substantia nigra dopaminergic neurons

    Ki Bum Um, Suyun Hahn ... Myoung Kyu Park
    The non-selective Na+ leak channel (NALCN) and the transient receptor potential 3 channel (TRPC3) cooperate in driving pacemaking in substantia nigra dopaminergic neurons.

    Sodium channels implement a molecular leaky integrator that detects action potentials and regulates neuronal firing

    Marco A Navarro, Autoosa Salari ... Lorin S Milescu
    Kinetic interactions between sodium channels and auxiliary factors create a molecular computational engine that can sense and regulate cellular excitability.
    1. Neuroscience

    Short-term synaptic dynamics control the activity phase of neurons in an oscillatory network

    Diana Martinez, Haroon Anwar ... Farzan Nadim
    The phase of a neuron in an oscillatory network can remain independent of network frequency when synaptic input strength and peak phase are adjusted in a frequency-dependent manner.
    1. Neuroscience

    Coupling between fast and slow oscillator circuits in Cancer borealis is temperature-compensated

    Daniel Powell, Sara A Haddad ... Eve Marder
    The mechanism that couples two rhythmic circuits is maintained over a large temperature range although both circuits are temperature-sensitive.
    1. Neuroscience

    Laser ablation of Dbx1 neurons in the pre-Bötzinger complex stops inspiratory rhythm and impairs output in neonatal mice

    Xueying Wang, John A Hayes ... Christopher A Del Negro
    Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality
    1. Neuroscience

    Ih block reveals separation of timescales in pyloric rhythm response to temperature changes in Cancer borealis

    Kyra Schapiro, JD Rittenberg ... Eve Marder
    The hyperpolarization-activated inward current plays an important role in regulating both smooth transitory responses and persistent increases in pyloric frequency during temperature fluctuations in Cancer borealis.
