    Valence biases in reinforcement learning shift across adolescence and modulate subsequent memory

    Gail M Rosenbaum, Hannah L Grassie, Catherine A Hartley
    Relative to children and adults, adolescents placed greater weight on negative prediction errors during learning and these age-varying learning idiosyncrasies biased subsequent memory for information associated with valenced outcomes.

    Uncertainty alters the balance between incremental learning and episodic memory

    Jonathan Nicholas, Nathaniel D Daw, Daphna Shohamy
    People use uncertainty for effective arbitration between episodic memory and incremental learning.

    Emotional learning retroactively promotes memory integration through rapid neural reactivation and reorganization

    Yannan Zhu, Yimeng Zeng ... Shaozheng Qin
    Emotional learning retroactively promotes memory integration for previously neutral events into episodic memory to foster future event predictions, through rapidly stimulating trial-specific reactivation of overlapping memory traces and reorganization of associated memories among the amygdala, hippocampal, and neocortical circuits.

    Gap junction networks in mushroom bodies participate in visual learning and memory in Drosophila

    Qingqing Liu, Xing Yang ... Aike Guo
    Gap junctions exist in Kenyon cells and Kenyon cell-mushroom body output neuron neural networks, and are also critical in visual learning and memory in Drosophila.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou, Stuart Greenhill ... Alcino J Silva
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    Signed and unsigned reward prediction errors dynamically enhance learning and memory

    Nina Rouhani, Yael Niv
    Throughout learning, both unexpected outcomes and the predictive value of cues modulate learning rate and episodic memory, thereby supporting two seemingly opposing theories of associative learning.

    Drep-2 is a novel synaptic protein important for learning and memory

    Till F M Andlauer, Sabrina Scholz-Kornehl ... Stephan J Sigrist
    Drep-2 is the first representative of the evolutionary conserved CIDE-N protein family found at synapses and is required for associative learning by functionally intersecting with metabotropic signaling.

    Age-related differences in prefrontal glutamate are associated with increased working memory decay that gives the appearance of learning deficits

    Milena Rmus, Mingjian He ... Matthew R Nassar
    Apparent age-related differences in learning are best accounted for by rapid decay of information in working memory, which is associated with levels of prefrontal glutamate.

    Misaligned feeding impairs memories

    Dawn H Loh, Shekib A Jami ... Christopher S Colwell
    The time at which mice consume food can dramatically affect hippocampal-dependent biochemistry, physiology, and learned behavior.

    Dynamics of immune memory and learning in bacterial communities

    Madeleine Bonsma-Fisher, Sidhartha Goyal
    Bacterial CRISPR immunity tracks phage mutations, creating immune diversity in bacterial populations that parallels phage genetic diversity and patterns of phage evolution that are determined by the type and degree of immune cross-reactivity in the CRISPR system.
