    Electrical and Ca2+ signaling in dendritic spines of substantia nigra dopaminergic neurons

    Travis A Hage et al.
    Dopaminergic cells uniquely receive input from a roughly equal mixture of synapses on dendritic spines and synapses formed directly on dendrites.

    Ultrastructural comparison of dendritic spine morphology preserved with cryo and chemical fixation

    Hiromi Tamada et al.
    Cryo preservation of brain tissue reveals dendritic spines with thinner necks compared to those prepared with chemical fixation.

    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.

    C. elegans neurons have functional dendritic spines

    Andrea Cuentas-Condori et al.
    Caenorhabditis elegans has bona fide dendritic spines, suggesting that the advantages of small model organisms, such as genetic manipulations and live-cell imaging, can be exploited to study dendritic spines.

    Synaptic pruning in the female hippocampus is triggered at puberty by extrasynaptic GABAA receptors on dendritic spines

    Sonia Afroz et al.
    Extrasynaptic GABAA receptors that emerge at puberty trigger adolescent synaptic pruning; pruning is prevented and cognition is impaired if the receptors are absent.

    Specific depletion of the motor protein KIF5B leads to deficits in dendritic transport, synaptic plasticity and memory

    Junjun Zhao et al.
    Two homologous kinesin motors, KIF5A and KIF5B, have distinct functions in dendritic spine morphogenesis, and KIF5B plays a role in synaptic plasticity and memory.

    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.

    Mutant huntingtin enhances activation of dendritic Kv4 K+ channels in striatal spiny projection neurons

    Luis Carrillo-Reid et al.
    In mouse models of Huntington's disease, striatal spiny projection neurons up-regulate dendritic potassium channels, which impairs their normal function, but a zinc finger gene therapy can reverse this deficit.

    Neurexin directs partner-specific synaptic connectivity in C. elegans

    Alison Philbrook et al.
    Investigation of synapse development using a single neuron system illuminates how individual neurons specify connectivity with their postsynaptic partners and the central role of the synaptic organizer neurexin in this process.

    Ablation of SNX6 leads to defects in synaptic function of CA1 pyramidal neurons and spatial memory

    Yang Niu et al.
    SNX6 regulates the distribution of a protein called Homer1b/c to distal dendrites, enabling the latter to stabilize the synapses and thereby support memory formation.
