    Asymmetric ON-OFF processing of visual motion cancels variability induced by the structure of natural scenes

    Juyue Chen et al.
    The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.

    The recovery of standing and locomotion after spinal cord injury does not require task-specific training

    Jonathan Harnie et al.
    Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Epigenetic regulation of lateralized fetal spinal gene expression underlies hemispheric asymmetries

    Sebastian Ocklenburg et al.
    Gene expression asymmetries in fetal spinal cord are triggered by epigenetic mechanisms suggesting that handedness has a spinal instead of a cortical origin.

    Mechanosensory neurons control the timing of spinal microcircuit selection during locomotion

    Steven Knafo et al.
    Bioluminescence monitoring and selective silencing in zebrafish larva reveal a novel sensorimotor circuit modulating speed in the moving spinal cord.

    Astrocytes refine cortical connectivity at dendritic spines

    W Christopher Risher et al.
    Spines with multiple excitatory contacts are potential sites for competition between thalamic and cortical axons, which is regulated by the astrocytes through the secreted synaptogenic protein hevin.

    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.

    Notochord vacuoles absorb compressive bone growth during zebrafish spine formation

    Jennifer Bagwell et al.
    Live imaging and genetic analyses revealed that notochord vacuoles play a critical role in spine morphogenesis by absorbing vertebral bone growth, thus implicating notochord mechanics in congenital scoliosis.

    Excitatory neurons are more disinhibited than inhibitory neurons by chloride dysregulation in the spinal dorsal horn

    Kwan Yeop Lee et al.
    The flow of somatosensory information through the spinal dorsal horn is regulated by synaptic inhibition, which acts upon excitatory and inhibitory interneurons, but the former are especially prone to disinhibition.

    Selective attenuation of Ether-a-go-go related K+ currents by endogenous acetylcholine reduces spike-frequency adaptation and network correlation

    Edward D Cui, Ben W Strowbridge
    Acetylcholine, a common modulator in the brain, controls spike-frequency adaptation by specifically attenuating Ether-a-go-go related K+ currents, thereby explaining many cortical network statistical changes often observed in vivo.
