    Direct neural pathways convey distinct visual information to Drosophila mushroom bodies

    Katrin Vogt et al.
    Building on previous work (Vogt et al. 2014), separate visual pathways have been identified to convey information for brightness and color to the learning-related area of the Drosophila brain.

    Offline replay supports planning in human reinforcement learning

    Ida Momennejad et al.
    fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.

    Rigid firing sequences undermine spatial memory codes in a neurodegenerative mouse model

    Jingheng Cheng, Daoyun Ji
    In a mouse model of neurodegeneration, hippocampal firing sequences that normally encode spatial memories become disengaged from external space.

    A single pair of neurons links sleep to memory consolidation in Drosophila melanogaster

    Paula R Haynes et al.
    Dorsal paired medial neurons, which are required for memory consolidation, promote sleep by inhibiting the excitation of mushroom body neurons.

    Dopaminergic neurons write and update memories with cell-type-specific rules

    Yoshinori Aso, Gerald M Rubin
    Building on previous work (Aso et al., 2014a; Aso et al., 2014b), cell-type-specific drivers and optogenetics are used to control the local release of dopamine and reveal that distinct learning rules are implemented in parallel memory units.

    Multiple neurons encode CrebB dependent appetitive long-term memory in the mushroom body circuit

    Yves F Widmer et al.
    The transcription factor CrebB mediates long-term memory formation in different neurons within the mushroom body learning circuit, including mushroom body intrinsic and output neurons but not dopaminergic input neurons.

    Developmental, cellular, and behavioral phenotypes in a mouse model of congenital hypoplasia of the dentate gyrus

    Amir Rattner et al.
    A mouse mutant in which nearly all dentate gyrus granule cells fail to develop provides a new window on the role of the dentate gyrus in spatial learning and memory.

    Presynaptic APP levels and synaptic homeostasis are regulated by Akt phosphorylation of huntingtin

    Julie Bruyère et al.
    Reducing Akt-mediated huntingtin phosphorylation decreases APP accumulation at the synapse by reducing its anterograde axonal transport and ameliorates learning and memory in a mouse model of familial Alzheimer disease.

    Inhibition enhances spatially-specific calcium encoding of synaptic input patterns in a biologically constrained model

    Daniel B Dorman et al.
    Inhibition enhances the spatial specificity of high calcium influx for cooperatively stimulated synapses, suggesting that inhibitory inputs may regulate both synapse-specific and heterosynaptic plasticity to support learning and memory.

    A prediction model of working memory across health and psychiatric disease using whole-brain functional connectivity

    Masahiro Yamashita et al.
    Human neuroimaging and machine learning reveals a generalizable relationship between brain connectivity and working memory ability across healthy populations and distinct psychiatric diagnoses.
