    Kv1.1 contributes to a rapid homeostatic plasticity of intrinsic excitability in CA1 pyramidal neurons in vivo

    Peter James Morgan et al.
    Short, theta-bursts of action potential firing decrease the global excitability of CA1 pyramidal neurons, providing an internal mechanism which could regulate their allocation to memory engrams.

    Nonlinear feedback drives homeostatic plasticity in H2O2 stress response

    Youlian Goulev et al.
    Nonlinear H2O2 scavenging by peroxiredoxins drives acquired stress resistance and replicative lifespan hormesis.

    Rem2 stabilizes intrinsic excitability and spontaneous firing in visual circuits

    Anna R Moore et al.
    In vivo and ex vivo analysis of the activity-regulated gene Rem2 in the mouse visual system sheds new light on the contribution of intrinsic excitability in circuit plasticity.

    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.

    Fast-spiking GABA circuit dynamics in the auditory cortex predict recovery of sensory processing following peripheral nerve damage

    Jennifer Resnik, Daniel B Polley
    Dynamic regulation of feedforward inhibition from parvalbumin-expressing inhibitory neurons is linked to the gradual restoration of cortical sensory processing following auditory nerve damage.

    Synergistic plasticity of intrinsic conductance and electrical coupling restores synchrony in an intact motor network

    Brian J Lane et al.
    Neural networks like the crustacean cardiac ganglion employ multi-faceted compensatory mechanisms to achieve the stability and robustness that are critical to long-term function.

    Spontaneous neurotransmission signals through store-driven Ca2+ transients to maintain synaptic homeostasis

    Austin L Reese, Ege T Kavalali
    Individual neurons can adjust the strength of their synapses by using spontaneous calcium influx through NMDA receptors to trigger the release of additional calcium from intracellular stores, which can in turn be used to regulate protein synthesis.

    Multivariate analysis of electrophysiological diversity of Xenopus visual neurons during development and plasticity

    Christopher M Ciarleglio et al.
    The diversity of electrophysiological phenotypes of neurons in a functional network increases over development, but can be modulated, and even reduced by sensory experience; allowing them to adapt to a changing and growing brain.

    Homeostatic synaptic depression is achieved through a regulated decrease in presynaptic calcium channel abundance

    Michael A Gaviño et al.
    Experiments at synapses between nerve and muscle cells in genetically modified fruit flies reveal how neurons compensate for perturbations that would otherwise cause excessive synaptic transmission.

    Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

    Paola Binda et al.
    Two hour deprivation of vision in one eye transiently boosts the representation of the deprived eye (suppressing the non-deprived eye) in adult human V1 and along the ventral pathway.
