    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.

    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.

    MicroRNAs mediate precise control of spinal interneuron populations to exert delicate sensory-to-motor outputs

    Shih-Hsin Chang et al.
    The miR-34/449 family is abundantly expressed in the central nervous system, and fine-tunes optimal numbers of spinal interneurons to ensure sensory-motor circuit outputs.

    Resting state functional connectivity in the human spinal cord

    Robert L Barry et al.
    Resting state spinal fMRI will be useful in studies of normal spinal cord function and central nervous system disorders.

    Sensory restoration by epidural stimulation of the lateral spinal cord in upper-limb amputees

    Santosh Chandrasekaran et al.
    Cervical spinal cord stimulation evokes sensory percepts in the missing hand and arm of people with upper-limb amputation, regardless of amputation level or time post-amputation.

    Planar cell polarity-mediated induction of neural stem cell expansion during axolotl spinal cord regeneration

    Aida Rodrigo Albors et al.
    During axolotl spinal cord regeneration adult neural stem cells reactivate an embryonic neuroepithelial cell-like gene program that implements planar cell polarity to orient cell divisions, coupling polarized spinal cord growth with stem cell self-renewal.

    Spinal microcircuits comprising dI3 interneurons are necessary for motor functional recovery following spinal cord transection

    Tuan V Bui et al.
    A genetically-defined population of spinal interneurons is reciprocally connected with spinal locomotor circuits and mediates recovery of locomotor function following spinal cord transection.

    Palmitoylation of LIM Kinase-1 ensures spine-specific actin polymerization and morphological plasticity

    Joju George et al.
    The protein-lipid modification palmitoylation targets the kinase LIMK1 to dendritic spines to ensure precise control of the size of individual spines in response to synaptic activation.

    Calretinin positive neurons form an excitatory amplifier network in the spinal cord dorsal horn

    Kelly M Smith et al.
    A signal amplifier network that transmits mechanical pain is delineated through characterising an excitatory interneuron population in the spinal cord dorsal horn and defining the postsynaptic populations they regulate.

    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui et al.
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.
