    The cation channel mechanisms of subthreshold inward depolarizing currents in the mice VTA dopaminergic neurons and their roles in the chronic-stress-induced depression-like behavior

    Jing Wang, Min Su ... Hailin Zhang
    NALCN and TRPC6 drive the subthreshold depolarization of VTA DA neurons and down regulation of TRPC6 contributes to reduced VTA DA neuron firing and chronic stress-induced depression-like behavior of mice.

    Basolateral amygdala oscillations enable fear learning in a biophysical model

    Anna Cattani, Don B Arnold ... Nancy Kopell
    Computational modeling suggests that the BLA is capable of producing the recorded LFP rhythms via interactions of interneuron subtypes, and that those rhythms may be necessary for associative learning.

    TMEM16 and OSCA/TMEM63 proteins share a conserved potential to permeate ions and phospholipids

    Augustus J Lowry, Pengfei Liang ... Yang Zhang
    Proteins in the Transmembrane Channel-Scramblase (TCS) superfamily share an evolutionarily conserved ability to permeate ions and phospholipids, challenging distinctions between ion channels and lipid scramblases.

    Exploring the K+ binding site and its coupling to transport in the neurotransmitter:sodium symporter LeuT

    Solveig G Schmidt, Andreas Nygaard ... Claus J Loland
    Potassium presumably binds to the Na1 site in LeuT, playing a role in inwardly rectifying the transport of substrates.

    Brain and molecular mechanisms underlying the nonlinear association between close friendships, mental health, and cognition in children

    Chun Shen, Edmund T Rolls ... Jianfeng Feng
    Close friend quantity is nonlinearly associated with various mental health and cognitive outcomes in children and could be partly explained by the structure of the social brain and the endogenous opioid system.

    Enhanced functional detection of synaptic calcium-permeable AMPA receptors using intracellular NASPM

    Ian Coombs, Cécile Bats ... Mark Farrant
    Intracellular NASPM, unlike the widely used spermine, fully blocks outward currents through calcium-permeable AMPA-type glutamate receptors, enabling an improved functional readout for this physiologically important receptor subtype in neurons.
