    SMC condensin entraps chromosomal DNA by an ATP hydrolysis dependent loading mechanism in Bacillus subtilis

    Larissa Wilhelm et al.
    The Smc–ScpAB complex-a prokaryotic ancestor of cohesin, condensin and Smc5/6-loads onto the bacterial chromosome by employing ATP hydrolysis to capture DNA fibers within its tripartite ring.

    Multi-neuron intracellular recording in vivo via interacting autopatching robots

    Suhasa B Kodandaramaiah et al.
    A robot capable of automatically obtaining blind whole cell patch clamp recordings from multiple neurons simultaneously guides four interacting electrodes in a coordinated fashion, avoiding mechanical coupling in the brain.

    The cerebellum linearly encodes whisker position during voluntary movement

    Susu Chen et al.
    Cerebellar Purkinje cells represent movements via bidirectional linear changes in spike rate, and activity from single cells is sufficient to reconstruct kinematic changes during bouts of free whisking.

    Feed-forward recruitment of electrical synapses enhances synchronous spiking in the mouse cerebellar cortex

    Andreas Hoehne et al.
    Transient recruitment of electrical synapses mediates precisely timed excitation and inhibition to enhance synchronized control of cerebellar cortical output.

    The effects of chloride dynamics on substantia nigra pars reticulata responses to pallidal and striatal inputs

    Ryan S Phillips et al.
    The effects of chloride homeostasis can explain diverse responses of basal ganglia output neurons to putatively inhibitory inputs and may tune these neurons' synchrony, oscillations and behavior in decision-making scenarios.

    Gradients in the biophysical properties of neonatal auditory neurons align with synaptic contact position and the intensity coding map of inner hair cells

    Alexander L Markowitz, Radha Kalluri
    The biophysical diversity that is intrinsic to spiral ganglion neurons emerges as spatial gradients during early post-natal development and endures through subsequent maturation to likely contribute to sound intensity coding.

    Kv2.1 mediates spatial and functional coupling of L-type calcium channels and ryanodine receptors in mammalian neurons

    Nicholas C Vierra et al.
    A potassium channel, as a nonconducting function, organizes compartmentalized neuronal calcium signaling microdomains via structural and functional coupling of plasma membrane and endoplasmic reticulum calcium channels.

    Optical estimation of absolute membrane potential using fluorescence lifetime imaging

    Julia R Lazzari-Dean et al.
    Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.

    Biophysics of object segmentation in a collision-detecting neuron

    Richard Burkett Dewell, Fabrizio Gabbiani
    Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.

    Dendritic sodium spikes are required for long-term potentiation at distal synapses on hippocampal pyramidal neurons

    Yujin Kim et al.
    At distal synapses onto hippocampal CA1 pyramidal neurons, synaptic plasticity is dependent on dendritically initiated sodium spikes, thus establishing a new role for voltage-gated sodium channels in the dendrites that may have important implications for how learning rules are implemented.
