    Noise-induced plasticity of KCNQ2/3 and HCN channels underlies vulnerability and resilience to tinnitus

    Shuang Li et al.
    Mice that successfully avoid developing tinnitus despite exposure to excessive noise show spontaneous recovery of KCNQ2/3 potassium channel activity associated with a reduction in HCN channel activity in auditory brainstem neurons.

    1. Neuroscience

    A dystonia-like movement disorder with brain and spinal neuronal defects is caused by mutation of the mouse laminin β1 subunit, Lamb1

    Yi Bessie Liu et al.
    A mouse with a defined mutation in an extracellular matrix protein that is expressed in selected neurons sheds light on circuit abnormalities producing transient hyperkinetic movements.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    Natural antisense transcripts regulate the neuronal stress response and excitability

    Xingguo Zheng et al.
    The mRNA that encodes a Drosophila sodium channel enables neurons to adapt to acute temperature changes, via a mechanism independent of its protein-coding role.

    Deletion of KCNQ2/3 potassium channels from PV+ interneurons leads to homeostatic potentiation of excitatory transmission

    Heun Soh et al.
    Loss of potassium channel activity from fast-spiking interneurons increases their excitability leading to unexpectedly increased fast excitatory transmission and seizure susceptibility.

    NOVA-dependent regulation of cryptic NMD exons controls synaptic protein levels after seizure

    Taesun Eom et al.
    The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.

    Intramuscular Neurotrophin-3 normalizes low threshold spinal reflexes, reduces spasms and improves mobility after bilateral corticospinal tract injury in rats

    Claudia Kathe et al.
    Delayed intramuscular gene therapy with neurotrophin-3 after corticospinal tract injury reduces spasticity and improves locomotion by treating underlying causes of spasticity.

    ErbB4 deletion in noradrenergic neurons in the locus coeruleus induces mania-like behavior via elevated catecholamines

    Shu-Xia Cao et al.
    Behavioral and molecular mechanistic studies elaborate the important role of ErbB4 in noradrenergic neurons associated with mania pathogenesis.

    Beyond excitation/inhibition imbalance in multidimensional models of neural circuit changes in brain disorders

    Cian O'Donnell et al.
    Computational modeling and analysis of mouse neural population data finds that the excitation/inhibition imbalance theory of brain disorders is too limited to account for key changes in neural activity statistics.
