    Visual landmarks sharpen grid cell metric and confer context specificity to neurons of the medial entorhinal cortex

    José Antonio Pérez-Escobar, Olga Kornienko ... Kevin Allen
    The firing rate of MEC neurons conveys information about visual landmarks.
    1. Neuroscience

    Fan cells in lateral entorhinal cortex directly influence medial entorhinal cortex through synaptic connections in layer 1

    Brianna Vandrey, Jack Armstrong ... Matthew F Nolan
    A synaptic circuit through which 'what' streams of information associated with the lateral entorhinal cortex may influence 'where' streams of information associated with the medial entorhinal cortex prior to their integration in the hippocampus.
    1. Neuroscience

    Structural development and dorsoventral maturation of the medial entorhinal cortex

    Saikat Ray, Michael Brecht
    The medial entorhinal cortex is important for spatial memory formation and matures from dorsal, where smaller spatial-scales are represented, to ventral, where larger spatial-scales are represented.
    1. Neuroscience

    Inter- and intra-animal variation in the integrative properties of stellate cells in the medial entorhinal cortex

    Hugh Pastoll, Derek L Garden ... Matthew F Nolan
    Setpoints that determine the integrative properties of neurons in the medial entorhinal cortex are established at a population level and differ between animals.
    1. Neuroscience

    Medial entorhinal cortex activates in a traveling wave in the rat

    J Jesús Hernández-Pérez, Keiland W Cooper, Ehren L Newman
    The existence of traveling waves in the medial entorhinal cortex, like those observed in the hippocampus, supports the hypothesis that traveling waves coordinate the activity of anatomically distributed circuits.
    1. Neuroscience

    Somatostatin interneurons activated by 5-HT2A receptor suppress slow oscillations in medial entorhinal cortex

    Roberto de Filippo, Benjamin R Rost ... Dietmar Schmitz
    Somatostatin interneurons are novel mediators of serotonergic modulation in entorhinal cortex via activation of 5-HT2A receptors, a receptor involved in the etiology of different psychiatric disorders.
    1. Neuroscience

    Synaptic interactions between stellate cells and parvalbumin interneurons in layer 2 of the medial entorhinal cortex are organized at the scale of grid cell clusters

    Li-Wen Huang, Derek LF Garden ... Matthew F Nolan
    New methods for investigating connectivity between genetically defined neuronal populations are introduced and used to investigate the organisation of excitatory-inhibitory interactions in the superficial entorhinal cortex.
    1. Neuroscience

    Local projections of layer Vb-to-Va are more prominent in lateral than in medial entorhinal cortex

    Shinya Ohara, Stefan Blankvoort ... Menno P Witter
    The connection from layer Vb-to-Va neurons, a key component of the canonical hippocampal-cortical output circuit, which is allegedly crucial for memory consolidation, is relatively stronger in lateral entorhinal cortex compared with the medial entorhinal cortex, thus suggesting different operating principles.
    1. Neuroscience

    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.
    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.
