    Optogenetic strategies for high-efficiency all-optical interrogation using blue-light-sensitive opsins

    Angelo Forli, Matteo Pisoni ... Tommaso Fellin
    A new soma-targeted variant of the large-conductance blue-light-sensitive opsin CoChR combined with advanced optical stimulation methods allows high-efficiency all-optical neuronal imaging and stimulation in mouse brain in vivo.
    1. Neuroscience

    A calibrated optogenetic toolbox of stable zebrafish opsin lines

    Paride Antinucci, Adna Dumitrescu ... Claire Wyart
    Generation of stable transgenic opsin lines together with in vivo calibration of their efficacy using behavioural and electrophysiological assays constitutes a novel optogenetic toolkit in zebrafish.
    1. Neuroscience

    Three-dimensional multi-site random access photostimulation (3D-MAP)

    Yi Xue, Laura Waller ... Nicolas Pégard
    A one-photon three-dimensional light sculpture technique has been developed and demonstrated for high spatio-temporal resolution photostimulation and imaging of dozens of neurons in the intact mouse brain in vivo.
    1. Neuroscience

    Pretectal neurons control hunting behaviour

    Paride Antinucci, Mónica Folgueira, Isaac H Bianco
    A discrete population of genetically accessible pretectal neurons controls visually guided hunting behaviour in larval zebrafish.
    1. Neuroscience

    Mechanosensory neurons control the timing of spinal microcircuit selection during locomotion

    Steven Knafo, Kevin Fidelin ... Claire Wyart
    Bioluminescence monitoring and selective silencing in zebrafish larva reveal a novel sensorimotor circuit modulating speed in the moving spinal cord.
    1. Neuroscience

    Aversive stimuli drive hypothalamus-to-habenula excitation to promote escape behavior

    Salvatore Lecca, Frank Julius Meye ... Manuel Mameli
    Glutamatergic signaling from the lateral hypothalamus instructs lateral habenular neurons for encoding aversive external stimuli to subsequently guide escape behaviours.
    1. Neuroscience

    Whole-organism behavioral profiling reveals a role for dopamine in state-dependent motor program coupling in C. elegans

    Nathan Cermak, Stephanie K Yu ... Steven W Flavell
    Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.
    1. Stem Cells and Regenerative Medicine

    Scleraxis-lineage cells are required for tendon homeostasis and their depletion induces an accelerated extracellular matrix aging phenotype

    Antonion Korcari, Anne EC Nichols ... Alayna E Loiselle
    Age-related tendon degeneration is initiated by loss of tenocytes associated with synthesis of high-turnover rate proteoglycans and glycoproteins.
    1. Neuroscience

    Clonally related, Notch-differentiated spinal neurons integrate into distinct circuits

    Saul Bello-Rojas, Martha W Bagnall
    Pairs of spinal cord neurons arising from a shared progenitor get input from and make outputs to mostly different synaptic partners.
    1. Neuroscience

    Synapse-specific opioid modulation of thalamo-cortico-striatal circuits

    William T Birdsong, Bart C Jongbloets ... Tianyi Mao
    By differentially modulating the two major excitatory inputs to the striatum, mu- and delta-opioid receptors regulate the balance between thalamic and cortical inputs to the striatum.
