    Cannabidiol interactions with voltage-gated sodium channels

    Lily Goodyer Sait et al.
    The high resolution crystal structure and electrophysiology of a sodium channel complex with cannabidiol, a drug approved for treatment of severe epilepsies, demonstrate the basis for its structural- functional effects.

    Ionic selectivity and thermal adaptations within the voltage-gated sodium channel family of alkaliphilic Bacillus

    Paul G DeCaen et al.
    Not all members of the bacteria sodium channel family are sodium channels - those found in Bacillus are highly adaptable and can be converted into many selectivity types.

    Binary architecture of the Nav1.2-β2 signaling complex

    Samir Das et al.
    X-ray crystallography reveals new conceptual insights into the location of the β2-subunit in the Nav channel signaling complex.

    Atomic mutagenesis in ion channels with engineered stoichiometry

    John D Lueck et al.
    Building on previous work (Pless, 2013), we argue that side-chain 'flip out' is a key event in potassium channel C-type inactivation, and propose a new method for encoding multiple noncanonical amino acids and controlling protein stoichiometry.

    Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

    Hongkang Zhang et al.
    Optogenetic tools enable sophisticated measurements of a voltage-gated sodium channel implicated in pain, as well as high-throughput screening of candidate channel blockers.

    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.

    A dual role for Cav1.4 Ca2+ channels in the molecular and structural organization of the rod photoreceptor synapse

    J Wesley Maddox et al.
    Ca2+ influx through Cav1.4 channels is required for the structural, but not the molecular organization of the rod photoreceptor synapse.

    Chronic postnatal chemogenetic activation of forebrain excitatory neurons evokes persistent changes in mood behavior

    Sthitapranjya Pati et al.
    Enhanced Gq-signaling-mediated activation of forebrain excitatory neurons in postnatal life programs enhanced anxiety-, despair- and schizophrenia-like behavior, recapitulating key aspects of the behavioral consequences of early life adversity.

    The effects of chloride dynamics on substantia nigra pars reticulata responses to pallidal and striatal inputs

    Ryan S Phillips et al.
    The effects of chloride homeostasis can explain diverse responses of basal ganglia output neurons to putatively inhibitory inputs and may tune these neurons' synchrony, oscillations and behavior in decision-making scenarios.

    Functional clustering of dendritic activity during decision-making

    Aaron Kerlin et al.
    In motor cortex pyramidal neurons, diverse task-related signals are distributed throughout the dendritic arbor and compartmentalized by dendritic distance and branching.
