    Chronic social isolation reduces 5-HT neuronal activity via upregulated SK3 calcium-activated potassium channels

    Derya Sargin et al.
    Serotonin neurons in chronically isolated mice become less responsive to excitatory stimulation, but inhibiting a distinctive calcium-activated potassium channel can restore both neuronal activity and behavior.

    Dendritic small conductance calcium-activated potassium channels activated by action potentials suppress EPSPs and gate spike-timing dependent synaptic plasticity

    Scott L Jones et al.
    The activation of small-conductance calcium-activated potassium channels in spines by action potentials regulates the induction of spike-timing dependent synaptic plasticity during low-frequency single action potential–EPSP pairing.

    Activation of the archaeal ion channel MthK is exquisitely regulated by temperature

    Yihao Jiang et al.
    Temperature-sensitivity of archaebacterial potassium channel MthK is regulated by RCK domain via alteration of allosteric coupling.

    Purinergic signaling in cochlear supporting cells reduces hair cell excitability by increasing the extracellular space

    Travis A Babola et al.
    Supporting cells in the cochlea change their shape in response to purinergic receptor activation, which influences hair cell excitability by altering potassium redistribution in the extracellular space.

    Histidine phosphorylation relieves copper inhibition in the mammalian potassium channel KCa3.1

    Shekhar Srivastava et al.
    The mammalian potassium channel KCa3.1, which is important for T- and B-cell activation, is inhibited by cytoplasmic copper, mediated by a histidine residue (His358) that is phosphorylated to activate the channel.

    The Ca2+-activated K+ current of human sperm is mediated by Slo3

    Christoph Brenker et al.
    The principal potassium ion channel in human sperm, Slo3, is primarily activated by calcium ions and controls the membrane potential of human sperm by intracellular calcium ion levels rather than intracellular pH.

    Non-linear developmental trajectory of electrical phenotype in rat substantia nigra pars compacta dopaminergic neurons

    Martial A Dufour et al.
    The development of the electrical phenotype of neurons can be precisely quantified and dissected using a combination of multi-variate statistical analyses and a systematic electrophysiological characterization of electrical properties.

    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.

    Slo1 is the principal potassium channel of human spermatozoa

    Nadja Mannowetz et al.
    Potassium ions enter and leave human sperm cells via a calcium-dependent ion channel that is also pH-independent.
