    A circuit mechanism for decision-making biases and NMDA receptor hypofunction

    Sean Edward Cavanagh et al.
    Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
    1. Neuroscience

    Cre-assisted fine-mapping of neural circuits using orthogonal split inteins

    Haojiang Luan et al.
    A genetic method allows neurons to be individually identified and characterized by combining information about both their developmental origins and their mature patterns of gene expression.
    1. Neuroscience

    Cellular resolution circuit mapping with temporal-focused excitation of soma-targeted channelrhodopsin

    Christopher A Baker et al.
    Combining spatial restriction of channelrhodopsin to the neuronal cell body with two photon excitation and calcium imaging will enable production of high resolution maps of neural circuitry.

    Brain-wide cellular resolution imaging of Cre transgenic zebrafish lines for functional circuit-mapping

    Kathryn M Tabor et al.
    A new resource of transgenic zebrafish lines facilitates precise targeting of neuronal cell-types within the brain, supported by online software for visualizing transgene expression patterns.

    Mapping the functional versatility and fragility of Ras GTPase signaling circuits through in vitro network reconstitution

    Scott M Coyle, Wendell A Lim
    A systems level reconstitution of H-Ras GTPase signaling reveals a rich space of tunable dynamic outputs and clarifies the consequences of oncogenic perturbations to signaling.

    P1 interneurons promote a persistent internal state that enhances inter-male aggression in Drosophila

    Eric D Hoopfer et al.
    A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.
    1. Neuroscience

    Adaptive learning and decision-making under uncertainty by metaplastic synapses guided by a surprise detection system

    Kiyohito Iigaya
    Computational modeling offers an explanation for why animals learn more quickly or slowly when their environment becomes more variable or stable.
    1. Neuroscience

    A bidirectional network for appetite control in larval zebrafish

    Caroline Lei Wee et al.
    Brain imaging and behavioral analysis reveal two opposing states of hunger, represented by anti-correlated lateral and caudal hypothalamic dynamics that are important for the homeostatic control of feeding in zebrafish.
    1. Neuroscience

    Separable neural signatures of confidence during perceptual decisions

    Tarryn Balsdon et al.
    Neural processes for perception and confidence can be separated thanks to computational electroencephalography, thus revealing a neural circuit specific to metacognition.
    1. Neuroscience

    Thalamocortical and corticothalamic pathways differentially contribute to goal-directed behaviors in the rat

    Fabien Alcaraz et al.
    Adaptive decision-making critically depends on antiparallel flows conveying distinct information within thalamocortical circuits, highlighting directionality of functional exchanges as a neural principle potentially at play in virtually any brain circuit with reciprocal projections.
