    A neural network model of when to retrieve and encode episodic memories

    Qihong Lu, Uri Hasson, Kenneth A Norman
    A neural network showed better prediction of upcoming states when it was selective in when it encoded and retrieved episodic memories, thereby explaining why humans show this selectivity in studies of naturalistic memory.

    Human hippocampal CA3 damage disrupts both recent and remote episodic memories

    Thomas D Miller, Trevor T-J Chong ... Clive R Rosenthal
    Human hippocampal cornu ammonis 3 damage impairs both recent and remote autobiographical episodic memory, and disrupts functional integration in medial temporal lobe subsystem regions of the default network.
    1. Neuroscience

    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.

    Oscillations support short latency co-firing of neurons during human episodic memory formation

    Frédéric Roux, George Parish ... Simon Hanslmayr
    Synchronization of neural firing in the medial temporal lobe at fast, but not slow, theta and gamma oscillations correlates with shorter latencies of co-firing and successful memory formation.
    1. Neuroscience

    Cortico-hippocampal network connections support the multidimensional quality of episodic memory

    Rose A Cooper, Maureen Ritchey
    Enhanced hippocampal-cortical network communication during memory retrieval flexibly tracks the quality and content of memories for complex past events.
    1. Neuroscience

    Distinct neural mechanisms underlie the success, precision, and vividness of episodic memory

    Franziska R Richter, Rose A Cooper ... Jon S Simons
    Combining fMRI with continuous model-based measures of retrieval enables the behavioral and neural dissociation of multiple components of episodic memory.

    Learning cortical representations through perturbed and adversarial dreaming

    Nicolas Deperrois, Mihai A Petrovici ... Jakob Jordan
    A cortical model inspired by cognitive theories and deep learning demonstrates how the combination of wakefulness, non-rapid eye movement (NREM), and REM dreams leads to the emergence of robust and semantically organized neuronal representations in higher cortical areas.
    1. Neuroscience

    Flexible use of memory by food-caching birds

    Marissa C Applegate, Dmitriy Aronov
    A novel laboratory paradigm for studying food-caching behavior in black-capped chickadees and contributions of memory to this behavior.

    The interpretation of computational model parameters depends on the context

    Maria Katharina Eckstein, Sarah L Master ... Anne GE Collins
    Context factors such as experimental task and model parameterization can significantly impact modeling results, such that across tasks, the same participants show different fitted parameter values, and parameters capture different cognitive processes across tasks.
    1. Neuroscience

    Hippocampal and cortical mechanisms at retrieval explain variability in episodic remembering in older adults

    Alexandra N Trelle, Valerie A Carr ... Anthony D Wagner
    The strength of pattern completion during memory retrieval, indexed by hippocampal activity and cortical reinstatement, explains within- and across-individual variability in episodic memory in older adults.
