    A framework for studying behavioral evolution by reconstructing ancestral repertoires

    Damián G Hernández et al.
    The behavioral repertoires from six species of flies are measured, and a statistical approach is developed to predict co-evolving behaviors, providing a potential framework for exploring behavioral evolution.

    The development of active binocular vision under normal and alternate rearing conditions

    Lukas Klimmasch et al.
    A new computational model explains how alternate rearing conditions affect the development of binocular vision.

    Whole-organism 3D quantitative characterization of zebrafish melanin by silver deposition micro-CT

    Spencer R Katz et al.
    Melanin staining for micro-CT imaging, using a novel application of ionic silver deposition, enables qualitative and quantitative 3D analysis of zebrafish pigmentation and reveals subtle phenotypes missed by light microscopy.

    A population-level invasion by transposable elements triggers genome expansion in a fungal pathogen

    Ursula Oggenfuss et al.
    The activation of transposable elements and relaxed purifying selection underpin an incipient expansion of the genome in populations of a major wheat pathogen.

    L-DOPA modulates activity in the vmPFC, nucleus accumbens, and VTA during threat extinction learning in humans

    Roland Esser et al.
    Encoding an expected, but absent, threat is modulated by dopaminergic neurotransmission that regulates success of extinction learning in humans.

    Single-cell analysis of the ventricular-subventricular zone reveals signatures of dorsal and ventral adult neurogenesis

    Arantxa Cebrian-Silla et al.
    Adult neural stem cells differ in the types of neurons they generate according to their location and new territories and genes associated with dorsal and ventral neurogenic lineages in the adult mouse brain are revealed.

    Sex-specific pubertal and metabolic regulation of Kiss1 neurons via Nhlh2

    Silvia Leon et al.
    The transcription factor Nhlh2 is a marker of arcuate Kiss1 neurons in adulthood that activates the promotor activity of Kiss1 and Tac3 genes and controls puberty onset and the response of KNDy neurons to leptin in male mice.

    Coupling between motor cortex and striatum increases during sleep over long-term skill learning

    Stefan M Lemke et al.
    Sleep spindles, distinctive brain activity patterns occurring in non-REM sleep, modify cross-area connectivity in the motor network relevant for behavioral flexibility, impacting subsequent behavior.

    Decoding locomotion from population neural activity in moving C. elegans

    Kelsey M Hallinen et al.
    Neurons in the brain exhibit activity with various relations to locomotion and these signals are best decoded by combining activities from many neurons.

    Dual expression of Atoh1 and Ikzf2 promotes transformation of adult cochlear supporting cells into outer hair cells

    Suhong Sun et al.
    Adult cochlear supporting cells (SCs) are plastic and respond to ectopic Ikzf2 and Atoh1, and hair cell damage by up-regulating HC and down-regulating their endogenous SC genes.
