    Intrinsic excitability mechanisms of neuronal ensemble formation

    Tzitzitlini Alejandre-García, Samuel Kim ... Rafael Yuste
    Optogenetic and electrical stimulation of primary visual cortex neurons reveals synaptic and cell-intrinsic mechanisms that underlie neuronal ensemble formation.

    Specialized coding patterns among dorsomedial prefrontal neuronal ensembles predict conditioned reward seeking

    Roger I Grant, Elizabeth M Doncheck ... James M Otis
    Excitatory output neurons in dorsomedial prefrontal cortex display heterogeneously specialized coding properties that evolve during cue-reward learning and predict cue-driven reward seeking.

    Coordinated neuronal ensembles in primary auditory cortical columns

    Jermyn Z See, Craig A Atencio ... Christoph E Schreiner
    Auditory cortical columns contain small subsets of neurons with highly synchronous activity (cNEs) that create robust sequences of coordinated activity suitable for enhanced information processing and signal transmission beyond the capability of individual neurons.

    A robust activity marking system for exploring active neuronal ensembles

    Andreas T Sørensen, Yonatan A Cooper ... Yingxi Lin
    A new system for tagging activated neuronal population offers multiple advantages over existing systems based on immediate early genes, including greater sensitivity and specificity, and suitability for easy application in species other than mice.

    Direct extraction of signal and noise correlations from two-photon calcium imaging of ensemble neuronal activity

    Anuththara Rupasinghe, Nikolas Francis ... Behtash Babadi
    An inference paradigm for extracting neuronal correlations from two-photon imaging data, without requiring intermediate spike deconvolution, provides significant performance gains over existing methods as demonstrated by theoretical analysis, simulation studies, and real-data applications.

    Long-term stability of cortical ensembles

    Jesús Pérez-Ortega, Tzitzitlini Alejandre-García, Rafael Yuste
    Spontaneous and visually evoked neuronal ensembles in mouse visual cortex can last for weeks, potentially supporting the long-lasting representation of perceptions and memories.

    A dentate gyrus-CA3 inhibitory circuit promotes evolution of hippocampal-cortical ensembles during memory consolidation

    Hannah Twarkowski, Victor Steininger ... Amar Sahay
    Parvalbumin inhibitory neuron-mediated feed-forward inhibition in dentate gyrus-CA3 circuit governs time-dependent re-organization of memory traces in hippocampal-cortical networks to support systems consolidation.

    Distinct memory engrams in the infralimbic cortex of rats control opposing environmental actions on a learned behavior

    Nobuyoshi Suto, Amanda Laque ... Friedbert Weiss
    Current findings help reconcile the contradictory reports regarding the role of infralimbic cortex in the environmental control of appetitive behavior.

    Stereotyped responses of Drosophila peptidergic neuronal ensemble depend on downstream neuromodulators

    Wilson Mena, Sören Diegelmann ... John Ewer
    The response of the peptidergic neurons that control a stereotyped behavior depends on the actions of a triggering neuropeptide, downstream neuropeptides and GABA inhibitory influences.
