    Episode 32: September 2016

    In this episode we hear about ancient proteins, aging mice, mosquito nets, resourceful plants and cocktail party conversations.
    1. Neuroscience

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Pioneer neurog1 expressing cells ingress into the otic epithelium and instruct neuronal specification

    Esteban Hoijman et al.
    Quantitative 4D image analysis identifies a group of cells which enter into the otic primordium during morphogenesis and instructs neuronal specification.

    2. Ecology

    Place recognition using batlike sonar

    Dieter Vanderelst et al.
    Echolocating bats may recognize locations in the environment (and navigate to them) by remembering the specific echo signature of those locations.
    1. Neuroscience

    Atoh1-dependent rhombic lip neurons are required for temporal delay between independent respiratory oscillators in embryonic mice

    Srinivasan Tupal et al.
    The rhythmic patterns of activity that underlie breathing are generated and coordinated by distinct populations of neurons within the brainstem.
    1. Neuroscience

    Retinal direction selectivity in the absence of asymmetric starburst amacrine cell responses

    Laura Hanson et al.
    Experimental and computational models reveal how parallel 'core' mechanisms shape direction selectivity at the dendrites of starburst amacrine cells and ganglion cells in the mouse retina.
    1. Neuroscience

    Motor context dominates output from purkinje cell functional regions during reflexive visuomotor behaviours

    Laura D Knogler et al.
    Purkinje cells of the cerebellum, a conserved vertebrate brain region important for sensorimotor integration, receive sensory and motor information from distinct input streams and are functionally clustered into modules reflecting the larval zebrafish's behavioral repertoire.
    1. Neuroscience

    Bed nucleus of the stria terminalis regulates fear to unpredictable threat signals

    Travis D Goode et al.
    The bed nucleus of the stria terminalis (BNST) is required for the expression of defensive behavior to uncertain threats, a function that is central to pathological anxiety.
    1. Neuroscience

    An NMDA receptor-dependent mechanism for subcellular segregation of sensory inputs in the tadpole optic tectum

    Ali S Hamodi et al.
    An activity-dependent mechanism sculpts subcellular segregation of sensory inputs.
    1. Neuroscience

    A hierarchy of timescales explains distinct effects of local inhibition of primary visual cortex and frontal eye fields

    Luca Cocchi et al.
    The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.
