    The entorhinal-DG/CA3 pathway in the medial temporal lobe retains visual working memory of a simple surface feature

    Weizhen Xie, Marcus Cappiello ... Weiwei Zhang
    High-resolution fMRI data reveal an often-neglected contribution of the medial temporal lobe circuitry to item-specific representation in visual working memory, suggesting the mechanism traditionally deemed dedicated to long-term memory can be exploited to support the quality of human working memory.

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

    Maureen Ritchey, Maria E Montchal ... Charan Ranganath
    The anterior and posterior parts of the hippocampus have distinct roles in the retrieval of contextual information in memories of recent experiences.
    1. Neuroscience

    Longitudinal stability of medial temporal lobe connectivity is associated with tau-related memory decline

    Quanjing Chen, Adam Turnbull ... Feng V Lin
    Phosphorylated tau was related to a loss of structural stability in medial temporal lobe connectivity, and this loss of stability moderated the relationship between phosphorylated tau accumulation and memory decline.

    Functional topography of the human entorhinal cortex

    Tobias Navarro Schröder, Koen V Haak ... Christian F Doeller
    By employing high-field fMRI and taking advantage of well-known global connectivity fingerprints and sensitivity to spatial and non-spatial information, it is shown that the entorhinal cortex is primarily divided into anterior and posterior subregions.

    Dissociable roles of the inferior longitudinal fasciculus and fornix in face and place perception

    Carl J Hodgetts, Mark Postans ... Kim S Graham
    Structure-function associations in medial temporal lobe reflect specialised, behaviourally-relevant neurocognitive circuits for the perception of faces and places.
    1. Neuroscience

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

    Melissa Hebscher, Jed A Meltzer, Asaf Gilboa
    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

    Activity in perirhinal and entorhinal cortex predicts perceived visual similarities among category exemplars with highest precision

    Kayla M Ferko, Anna Blumenthal ... Stefan Köhler
    The present findings reveal that subjectively perceived similarities between objects, including those unique to individual observers, are reflected with highest fidelity at the apex of the ventral visual pathway in the medial temporal lobe.
    1. Neuroscience

    Phase-tuned neuronal firing encodes human contextual representations for navigational goals

    Andrew J Watrous, Jonathan Miller ... Joshua Jacobs
    Prospective navigational goals are represented by single neuron firing rates and firing relative to slow oscillatory phase (phase coding) in the human medial temporal lobe.
    1. Neuroscience

    Functional subregions of the human entorhinal cortex

    Anne Maass, David Berron ... Emrah Düzel
    By employing high-field fMRI to measure connectivity with the hippocampus and adjacent parahippocampal structures within the medial temporal lobe, it is shown that the entorhinal cortex can be divided into anterior-lateral and posterior-medial subregions.
    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.
