    Supramammillary nucleus synchronizes with dentate gyrus to regulate spatial memory retrieval through glutamate release

    Yadong Li et al.
    Multi-fiber photometry recording and circuit-based manipulation in vivo identify a long-range SuM-DG circuit linking two highly correlated subcortical regions to regulate spatial memory retrieval through SuM glutamate transmission.

    Temporal structure in associative retrieval

    Zeb Kurth-Nelson et al.
    Neural representations are fast-evolving trajectories, and distinct components of these trajectories reappear during retrieval with distinct consequences for learning.

    Imaging a memory trace over half a life-time in the medial temporal lobe reveals a time-limited role of CA3 neurons in retrieval

    Vanessa Lux et al.
    The retrieval of recent memories and very remote memories may rely on distinct regions of the hippocampus.
    1. Neuroscience

    Schematic memory components converge within angular gyrus during retrieval

    Isabella C Wagner et al.
    Upon retrieval, the angular gyrus recombines distinct, consolidated schema components into one memory representation.

    A causal role for the precuneus in network-wide theta and gamma oscillatory activity during complex memory retrieval

    Melissa Hebscher et al.
    Inhibitory noninvasive stimulation to the precuneus disrupts theta and gamma oscillatory coupling between medial temporal lobes and neocortical regions during complex personal memory retrieval.
    1. Neuroscience

    Hippocampal neurogenesis enhancers promote forgetting of remote fear memory after hippocampal reactivation by retrieval

    Rie Ishikawa et al.
    Forgetting of remote fear memory is promoted by increased hippocampal neurogenesis only after hippocampal reactivation by long time memory retrieval.
    1. Neuroscience

    Delay-dependent contributions of medial temporal lobe regions to episodic memory retrieval

    Maureen Ritchey et al.
    The anterior and posterior parts of the hippocampus have distinct roles in the retrieval of contextual information in memories of recent experiences.
    1. Neuroscience

    Enhancement of fear memory by retrieval through reconsolidation

    Hotaka Fukushima et al.
    Retrieval enhances fear memory through reconsolidation by activating calcineurin-induced protein degradation and CREB-mediated gene expression in amygdala, hippocampus, and mPFC.
    1. Neuroscience

    Tagging motor memories with transcranial direct current stimulation allows later artificially-controlled retrieval

    Daichi Nozaki et al.
    Noninvasive brain stimulation can artificially tag and retrieve human motor memories by altering the background activity patterns of the sensorimotor cortex.
    1. Neuroscience

    Successful retrieval of competing spatial environments in humans involves hippocampal pattern separation mechanisms

    Colin T Kyle et al.
    Functional magnetic resonance imaging and multivariate pattern analysis reveal remapping-like behavior during successful retrieval of competing environments, while unsuccessful retrieval is accompanied by reinstatement of interfering representations.
