    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.

    The shared and unique neural correlates of personal semantic, general semantic, and episodic memory

    Annick FN Tanguay, Daniela J Palombo ... Louis Renoult
    Four types of declarative memory rely on different weightings of similar component processes, according to fMRI and subjective ratings.
    1. Neuroscience

    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.

    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.

    Episodic-like memory trace in awake replay of hippocampal place cell activity sequences

    Susumu Takahashi
    What will happen where and when could be predicted by the sequential reactivation of place cells that occurs while an animal pauses, suggesting that the replay is linked to mental time travel.
    1. Neuroscience

    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.
    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.
    1. Neuroscience

    Distinct population and single-neuron selectivity for executive and episodic processing in human dorsal posterior cingulate

    Lyndsey Aponik-Gremillion, Yvonne Y Chen ... Brett L Foster
    Invasive recordings from human dorsal posterior cingulate cortex show neural population responses occur for only executive tasks, while single neuron responses occur for specific executive or episodic cognitive tasks.
    1. Neuroscience

    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

    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.
