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

    Salvatore Lecca et al.
    Glutamatergic signaling from the lateral hypothalamus instructs lateral habenular neurons for encoding aversive external stimuli to subsequently guide escape behaviours.

    Nociceptive interneurons control modular motor pathways to promote escape behavior in Drosophila

    Anita Burgos et al.
    A class of interneuron is identified that promotes escape behavior downstream of nociceptor inputs via connections to nociceptive integrator and premotor networks.

    The Natural History of Model Organisms: Insights into the evolution of social systems and species from baboon studies

    Julia Fischer et al.
    Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

    Correcting for physical distortions in visual stimuli improves reproducibility in zebrafish neuroscience

    Timothy W Dunn, James E Fitzgerald
    Computational analyses quantitatively account for optical refraction at air-water interfaces to enable visual neuroscientists to present distortion-free stimuli to underwater animals.

    A cross-modality enhancement of defensive flight via parvalbumin neurons in zona incerta

    Xiyue Wang et al.
    Parvalbumin positive GABAergic neurons in the ventral zona incerta receive input from somatosensory cortex and enhance sound-induced flight behavior, which underlies a cross-modality facilitation of defensive behavior by somatosensory input.

    MAPLE (modular automated platform for large-scale experiments), a robot for integrated organism-handling and phenotyping

    Tom Alisch et al.
    A new versatile, autonomous, robotic experimental platform (MAPLE) can increase the throughput of biological experiments by automating the growth and phenotyping of a variety of model organisms.

    Characterizing a psychiatric symptom dimension related to deficits in goal-directed control

    Claire M Gillan et al.
    A dimensional approach to psychiatry demonstrates the specificity and generalizability of a neurocognitive marker of compulsive behavior and intrusive thought via large-scale online testing.

    Interplay of cell dynamics and epithelial tension during morphogenesis of the Drosophila pupal wing

    Raphaël Etournay et al.
    Autonomous patterns of cell contraction in the context of localized apical extracellular matrix constraints specify tissue stresses that reshape the wing epithelium.

    Vocal development in a Waddington landscape

    Yayoi Teramoto et al.
    An integrated landscape framework shows how the coordinated changes in vocal apparatus, muscles, nervous system, and social interaction together influence the trajectory of vocal development.

    Vertex sliding drives intercalation by radial coupling of adhesion and actomyosin networks during Drosophila germband extension

    Timothy E Vanderleest et al.
    Tricellular vertices possess sliding behaviors that harness radial forces and drive cell shape changes and intercalation in an epithelial tissue.
