    Enhanced excitability of cortical neurons in low-divalent solutions is primarily mediated by altered voltage-dependence of voltage-gated sodium channels

    Briana J Martiszus et al.
    External calcium regulates neuronal excitability via its actions on voltage-gated sodium channels but not by regulating NALCN via the calcium-sensing receptor.

    Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

    Marianne J Bezaire et al.
    Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.

    Sam68/KHDRBS1-dependent NF-κB activation confers radioprotection to the colon epithelium in γ-irradiated mice

    Kai Fu et al.
    Building on previous work (Fu et al., 2016), we demonstrate the critical role of Sam68 in orchestrating genotoxic stress-initiated NF-κB signaling in the colon and the pathophysiological relevance of Sam68-dependent NF-κB activation in colonic cell survival/recovery from extrinsic DNA damage.

    Computational mechanisms of curiosity and goal-directed exploration

    Philipp Schwartenbeck et al.
    Distinct computational levels of uncertainty compel agents to gain information about hidden states in the world (‘active inference’) or optimise their ‘world model’ as such (‘active learning’).

    Biophysical mechanisms in the mammalian respiratory oscillator re-examined with a new data-driven computational model

    Ryan S Phillips et al.
    Computational modeling motivated by recent experiments clarifies biophysical mechanisms generating the rhythm and amplitude of breathing at the level of neurons and brain circuits in mammals.

    The microbiota protects from viral-induced neurologic damage through microglia-intrinsic TLR signaling

    D Garrett Brown et al.
    Immune stimulation from the microbiota prevents neurological damage associated with viral infection of the central nervous system.

    Intrinsic cooperativity potentiates parallel cis-regulatory evolution

    Trevor R Sorrells et al.
    Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

    Systemic and local cues drive neural stem cell niche remodelling during neurogenesis in Drosophila

    Pauline Spéder, Andrea H Brand
    Cross talk between neural stem cells and their glial niche enables the niche to adapt to the evolving needs of the stem cells throughout development.

    mTORC1 is necessary but mTORC2 and GSK3β are inhibitory for AKT3-induced axon regeneration in the central nervous system

    Linqing Miao et al.
    The kinase AKT acts as a nodal point that coordinates both positive and negative cues to regulate the regeneration of central nervous system axons in adult mice.

    High temperature sensitivity is intrinsic to voltage-gated potassium channels

    Fan Yang, Jie Zheng
    Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.
