    Na+/K+ pump interacts with the h-current to control bursting activity in central pattern generator neurons of leeches

    Daniel Kueh, William H Barnett ... Ronald L Calabrese
    The dynamic current generated Na+/K+ pump interacts with the h-current to control the bursting activity of oscillator heart interneurons.

    Maturation of persistent and hyperpolarization-activated inward currents shapes the differential activation of motoneuron subtypes during postnatal development

    Simon A Sharples, Gareth B Miles
    Electrophysiological recordings from mouse spinal motoneurons reveal key roles for ion channels in establishing the differential activation of motoneuron subtypes during postnatal development.
    1. Neuroscience

    The mTOR pathway genes MTOR, Rheb, Depdc5, Pten, and Tsc1 have convergent and divergent impacts on cortical neuron development and function

    Lena H Nguyen, Youfen Xu ... Angelique Bordey
    Expression of mTORC1 pathway gene variants in mouse medial prefrontal cortex leads to shared alterations in pyramidal neuron morphology, positioning, and membrane excitability but different changes in excitatory synaptic transmission.

    Short-term exposure to intermittent hypoxia leads to changes in gene expression seen in chronic pulmonary disease

    Gang Wu, Yin Yeng Lee ... David F Smith
    RNA profiles from lungs of mice exposed to intermittent hypoxia shared similarity with gene expression changes in human lung from patients with pulmonary diseases, including pulmonary hypertension, COPD, and asthma.

    Unique membrane properties and enhanced signal processing in human neocortical neurons

    Guy Eyal, Matthijs B Verhoog ... Idan Segev
    Models and experiments reveal that human L2/3 pyramidal neurons have distinctively low specific membrane capacitance which might have a significant impact on signal processing in human neocortex.

    Intermittent hypoxia mediated by TSP1 dependent on STAT3 induces cardiac fibroblast activation and cardiac fibrosis

    Qiankun Bao, Bangying Zhang ... Guangping Li
    Targeting STAT3 provides a potential therapeutic strategy for obstructive sleep apnea-related fibrotic heart disease mediated by TSP1.

    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.

    Synaptic cell adhesion molecule Cdh6 identifies a class of sensory neurons with novel functions in colonic motility

    Julieta Gomez-Frittelli, Gabrielle Frederique Devienne ... Julia A Kaltschmidt
    Cadherin-6 (Cdh6) marks gut-intrinsic sensory neurons, and optogenetic activation of Cdh6+ sensory neurons is sufficient to evoke colonic motor complexes.

    Drosophila HCN mediates gustatory homeostasis by preserving sensillar transepithelial potential in sweet environments

    MinHyuk Lee, Se Hoon Park ... KyeongJin Kang
    A hyperpolarization-activated cation channel, counteracting membrane depolarization, delimits the excitability of receptor neurons subjected to naturally prolonged stimulation to preserve the function of neighboring receptor neurons in Drosophila gustation.
    1. Neuroscience

    Kv1.1 contributes to a rapid homeostatic plasticity of intrinsic excitability in CA1 pyramidal neurons in vivo

    Peter James Morgan, Romain Bourboulou ... Jérôme Epsztein
    Short, theta-bursts of action potential firing decrease the global excitability of CA1 pyramidal neurons, providing an internal mechanism which could regulate their allocation to memory engrams.
