    Episode 25: November 2015

    In this episode we hear about deep-sea bacteria, cigarette smoke and lung disease, antibiotic resistance, unconscious perception, and the benefits of sleep.
    1. Neuroscience

    In vivo assessment of the neural substrate linked with vocal imitation accuracy

    Julie Hamaide et al.
    Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.
    1. Neuroscience

    Brain signatures of a multiscale process of sequence learning in humans

    Maxime Maheu et al.
    Evidence for multiple brain systems for sequence processing involving statistical inferences at multiple scales.
    1. Neuroscience

    Decision and navigation in mouse parietal cortex

    Michael Krumin et al.
    When mice use vision to choose their trajectories, a large fraction of parietal cortex activity can be precisely predicted from navigational attributes such as spatial position and heading.
    1. Neuroscience

    A flexible framework for simulating and fitting generalized drift-diffusion models

    Maxwell Shinn et al.
    Sophisticated decision-making mechanisms and complex experimental paradigms can be modeled, simulated, and fit to empirical response time data, using a flexible and efficient computational modeling framework.
    1. Neuroscience

    Motor selection dynamics in FEF explain the reaction time variance of saccades to single targets

    Christopher K Hauser et al.
    Oculomotor circuits are always busy planning the next eye movement, and this explains why, when a visual target appears, some eye movements toward it are produced very quickly whereas others take a long time to prepare.
    1. Neuroscience

    Oxytocin modulates human chemosensory decoding of sex in a dose-dependent manner

    Kepu Chen et al.
    Oxytocin, but not the structurally similar vasopressin, modulates both the chemosensory decoding of femininity in straight men and that of masculinity in gay men in an inverted-U-shaped manner.

    Adult chondrogenesis and spontaneous cartilage repair in the skate, Leucoraja erinacea

    Aleksandra Marconi et al.
    The ability of cartilaginous fishes to generate new cartilage through adulthood, and to spontaneously repair damaged cartilage, could shed light on novel cell-based therapies for cartilage injury in mammals.
    1. Neuroscience

    Causal evidence for lateral prefrontal cortex dynamics supporting cognitive control

    Derek Evan Nee, Mark D'Esposito
    Non-invasive brain stimulation tests and refines a model of lateral prefrontal cortex neural dynamics supporting cognitive control.
    1. Neuroscience

    Serial, parallel and hierarchical decision making in primates

    Ariel Zylberberg et al.
    A comparison between hierarchical and flat models of decision-making refutes flat models because they lack flexibility and are not supported by behavioral and neural data.
