    Episode 54: February 2019

    In this episode, we hear about colour vision in bats, frog vocal systems, ageing, problematic cell lines and how larger neurons could lead to a higher IQ.

    Endothelial heterogeneity across distinct vascular beds during homeostasis and inflammation

    Ankit Jambusaria et al.
    Vascular endothelial cells in the brain, heart and lung exhibit tissue-specific heterogeneity and plasticity, expressing genes that were traditionally thought to be only expressed by the surrounding parenchymal tissue cells.
    1. Neuroscience

    Dopamine neuron ensembles signal the content of sensory prediction errors

    Thomas A Stalnaker et al.
    Dopamine neurons function as an ensemble to signal a multidimensional feature prediction error.
    1. Developmental Biology

    Antagonistic regulation by insulin-like peptide and activin ensures the elaboration of appropriate dendritic field sizes of amacrine neurons

    Jiangnan Luo et al.
    Afferent-derived factors control the elaboration of appropriate and robust sizes of dendritic arbors by dynamically modulating dendritic growth parameters.

    2. Chromosomes and Gene Expression

    Translational regulation of protrusion-localized RNAs involves silencing and clustering after transport

    Konstadinos Moissoglu et al.
    RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.
    1. Neuroscience

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

    William T Birdsong et al.
    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.

    ATP-induced asymmetric pre-protein folding as a driver of protein translocation through the Sec machinery

    Robin A Corey et al.
    How the process of protein folding may be controlled by the Sec machinery to assist protein transport across membranes.

    Non-selective inhibition of inappropriate motor-tendencies during response-conflict by a fronto-subthalamic mechanism

    Jan R Wessel et al.
    Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.
    1. Neuroscience

    A virtual burrow assay for head–fixed mice measures habituation, discrimination, exploration and avoidance without training

    Andrew JP Fink et al.
    A naturalistic assay for head-fixed mice permits observation of a diverse set of innate and learned behaviors without requiring any training.

    Tenectin recruits integrin to stabilize bouton architecture and regulate vesicle release at the Drosophila neuromuscular junction

    Qi Wang et al.
    Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.
