    Context-dependent relationships between locus coeruleus firing patterns and coordinated neural activity in the anterior cingulate cortex

    Siddhartha Joshi, Joshua I Gold
    Simultaneous recordings in brainstem and cortex, combined with pupillometry, show that changes in coordinated activity in anterior cingulate cortex are related to distinct patterns of pupil-linked activation of the locus coeruleus-norepinephrine system.

    Computation identifies structural features that govern neuronal firing properties in slowly adapting touch receptors

    Daine R Lesniak, Kara L Marshall ... Ellen A Lumpkin
    Computer simulations show that the firing patterns of branched touch receptors can be set in part by the organization of their sensory endings in the skin.

    Supercomputer framework for reverse engineering firing patterns of neuron populations to identify their synaptic inputs

    Matthieu K Chardon, Y Curtis Wang ... Charles J Heckman
    Estimating the organization of supraspinal input to motoneurons in humans is not currently possible, but a promising reverse engineering technique has been developed using large-scale supercomputing and computational neuroscience.

    Estradiol elicits distinct firing patterns in arcuate nucleus kisspeptin neurons of females through altering ion channel conductances

    Jian Qiu, Margaritis Voliotis ... Martin J Kelly
    Kiss1ARH neurons transition from synchronous to burst firing under preovulatory levels of E2, causing a shift from peptidergic to glutamatergic transmission that drives the GnRH surge through enhanced glutamate neurotransmission.

    Two opposite voltage-dependent currents control the unusual early development pattern of embryonic Renshaw cell electrical activity

    Juliette Boeri, Claude Meunier ... Antonny Czarnecki
    A simple mechanism, based on the synergy of two major opposing voltage-dependent currents that are ubiquitous in neurons, produces functional diversity of developing Renshaw cells in the embryo.

    Firing patterns of ventral hippocampal neurons predict the exploration of anxiogenic locations

    Hugo Malagon-Vina, Stéphane Ciocchi, Thomas Klausberger
    A novel behavioural paradigm reveals how neurons in the ventral hippocampus dynamically adapt their firing activity after the introduction of an anxiogenic location.

    Spatial cell firing during virtual navigation of open arenas by head-restrained mice

    Guifen Chen, John Andrew King ... Neil Burgess
    A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.

    Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

    Marianne J Bezaire, Ivan Raikov ... Ivan Soltesz
    Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.

    Experience-driven rate modulation is reinstated during hippocampal replay

    Margot Tirole, Marta Huelin Gorriz ... Daniel Bendor
    Hippocampal place cells modulate their firing rate during replay events to reflect the increases, or decreases, in firing rate experienced between contexts during behavior.
    1. Neuroscience

    Dendritic nonlinearities are tuned for efficient spike-based computations in cortical circuits

    Balázs B Ujfalussy, Judit K Makara ... Máté Lengyel
    Dendrites combine the inputs that they receive from other neurons using calculations that have been optimized for those particular input patterns.
