    Mapping the function of neuronal ion channels in model and experiment

    William F Podlaski et al.
    The ion channel genealogy resource is a comprehensive and intuitive comparison tool for ion channel models and experimental data, helping to visualize their similarity and function to facilitate better experimentally-constrained modeling.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey et al.
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    Mechanistic insights into a TIMP3-sensitive pathway constitutively engaged in the regulation of cerebral hemodynamics

    Carmen Capone et al.
    Extracellular matrix signaling constitutively regulates cerebral blood flow in both physiological and pathological settings.

    Stochastic and deterministic dynamics of intrinsically irregular firing in cortical inhibitory interneurons

    Philipe RF Mendonça et al.
    A-type potassium conductances influence the distinctive firing behaviour of irregular-spiking interneurons.

    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova et al.
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    KCNE1 tunes the sensitivity of KV7.1 to polyunsaturated fatty acids by moving turret residues close to the binding site

    Johan E Larsson et al.
    An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.

    Dendritic sodium spikes are required for long-term potentiation at distal synapses on hippocampal pyramidal neurons

    Yujin Kim et al.
    At distal synapses onto hippocampal CA1 pyramidal neurons, synaptic plasticity is dependent on dendritically initiated sodium spikes, thus establishing a new role for voltage-gated sodium channels in the dendrites that may have important implications for how learning rules are implemented.

    NG2 glial cells integrate synaptic input in global and dendritic calcium signals

    Wenjing Sun et al.
    NG2 glial cells respond to synaptic input with calcium signals in the absence of action potentials and process synaptic depolarizations with somatic and dendritic voltage gated channels.

    Tarantula toxins use common surfaces for interacting with Kv and ASIC ion channels

    Kanchan Gupta et al.
    The tarantula toxins psalmotoxin and guangxitoxin have a similar concave surface for interacting with α-helices in voltage-gated and acid-sensing ion channels.

    Straightjacket/α2δ3 deregulation is associated with cardiac conduction defects in myotonic dystrophy type 1

    Emilie Auxerre-Plantié et al.
    Drosophila DM1 models suggest that elevated cardiac expression of straightjacket/α2δ3, a regulatory subunit of voltage-gated calcium channel, contributes to cardiac conduction defects in DM1.
