    Cerebellar learning using perturbations

    Guy Bouvier et al.
    A proposal for a complete cellular/network implementation of trial-and-error motor learning in the olivo-cerebellar system.

    Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner

    Feng-Ching Tsai et al.
    Ezrin, an important actin-membrane linker, can zip adjacent membranes, be enriched to positively-curved membranes when phosphorylated and to negatively-curved membranes through a direct interaction with membrane curvature sensor I-BAR domain proteins.

    Changes to social feeding behaviors are not sufficient for fitness gains of the Caenorhabditis elegans N2 reference strain

    Yuehui Zhao et al.
    Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

    Dopamine neuron glutamate cotransmission evokes a delayed excitation in lateral dorsal striatal cholinergic interneurons

    Nao Chuhma et al.
    Dopamine neurons make novel glutamatergic connections to striatal cholinergic interneurons in the lateral dorsal striatum that are mediated by metabotropic glutamate receptors coupled to TrpC channels.

    Synapse-specific and compartmentalized expression of presynaptic homeostatic potentiation

    Xiling Li et al.
    Genetic and electrophysiological analyses reveal that the mechanisms orchestrating the induction and expression of homeostatic plasticity are compartmentalized and operate with exquisite specificity on both sides of the synapse.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    A theory of working memory without consciousness or sustained activity

    Darinka Trübutschek et al.
    Visual information can be maintained in non-conscious working memory for several seconds via short-term changes in synaptic weights.

    A subset of ipRGCs regulates both maturation of the circadian clock and segregation of retinogeniculate projections in mice

    Kylie S Chew et al.
    A single subpopulation of photoreceptors constitutes a shared node in the neural networks that regulate light-dependent maturation of the circadian clock and light-independent refinement of retinal ganglion cell projections to the brain.

    The Na+/Ca2+, K+ exchanger NCKX4 is required for efficient cone-mediated vision

    Frans Vinberg et al.
    Molecular, genetic, and functional analysis is used to show that the olfactory Na+/Ca2+, K+ exchanger NCKX4 is expressed in cone photoreceptors and is critical for the wide operating range and high temporal resolution of cone-mediated vision.

    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.
