    Cerebellar modulation of synaptic input to freezing-related neurons in the periaqueductal gray

    Christopher E Vaaga et al.
    The mouse cerebellum regulates innate defensive neural circuitry by tonically controlling dopamine release in the periaqueductal gray, thereby modulating synaptic responses of the Chx10-positive neurons that generate freezing behavior.

    Prediction signals in the cerebellum: beyond supervised motor learning

    Court Hull
    Emerging evidence suggests a broad role for cerebellar circuits in generating and testing predictions about movement, reward, and diverse cognitive processes.

    Movement-related coupling of human subthalamic nucleus spikes to cortical gamma

    Petra Fischer et al.
    When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.

    Identification of slit3 as a locus affecting nicotine preference in zebrafish and human smoking behaviour

    Judit García-González et al.
    Zebrafish studies are able to predict loci and biological pathways affecting human behaviour, paving the way to better understanding of the biological underpinnings of psychiatric disease.

    Chemoptogenetic ablation of neuronal mitochondria in vivo with spatiotemporal precision and controllable severity

    Wenting Xie et al.
    Novel transgenic zebrafish lines allow selective ablation of neuronal mitochondria by far red light, providing a powerful tool for investigating mitochondrial homeostasis in neurons and mitochondrial mechanisms in neurological disease.

    ARL13B regulates Sonic hedgehog signaling from outside primary cilia

    Eduardo D Gigante et al.
    ARL13B regulates cell ciliation and cilia length from within cilia and Sonic hedgehog response from outside of cilia indicating the two processes can be spatially uncoupled.

    Organic electrochemical transistor arrays for real-time mapping of evoked neurotransmitter release in vivo

    Kai Xie et al.
    An implantable device based on organic electrochemical transistors is developed for quantitative mapping of neurotransmitter release across multiple brain regions, revealing a cross-talk between the mesolimbic and nigrostriatal dopaminergic pathways.

    Synaptic mechanisms underlying modulation of locomotor-related motoneuron output by premotor cholinergic interneurons

    Filipe Nascimento et al.
    The pairing of chemogenetic and electrophysiological approaches reveals mechanisms by which cholinergic synapses modulate the final motor output of the nervous system.

    Distinct inactive conformations of the dopamine D2 and D3 receptors correspond to different extents of inverse agonism

    J Robert Lane et al.
    The occupation of a sub-pocket near the Na+-binding site in D2R by the Na+-insensitive antagonists is the structural basis for their greater inverse agonism than that of the Na+-sensitive ligands.
