    A tissue-specific, Gata6-driven transcriptional program instructs remodeling of the mature arterial tree

    Marta Losa et al.
    The transcription factor GATA6 selects the embryonic vessels that will be reorganized into the major thoracic arteries by promoting local differentiation of vascular smooth muscle cells.

    Embryonic origin and serial homology of gill arches and paired fins in the skate, Leucoraja erinacea

    Victoria A Sleight, J Andrew Gillis
    Development from dual-origin mesenchyme with common competence explains anatomical parallels and shared patterning of the jawed vertebrate gill arch and paired fin skeletons.

    Intermediate progenitors support migration of neural stem cells into dentate gyrus outer neurogenic niches

    Branden R Nelson et al.
    Multiphoton live-imaging illuminates the dynamic underpinnings of how different types of progenitor cells migrate and interact to robustly build the mammalian Dentate Gyrus neural circuitry and new outer neurogenic niche.

    Neural tuning matches frequency-dependent time differences between the ears

    Victor Benichoux et al.
    Complex properties of space-sensitive auditory neurons in cats mirror the complexity of acoustical environments.

    Hedgehog signaling patterns the oral-aboral axis of the mandibular arch

    Jingyue Xu et al.
    SHH signaling acts through FOXF1/2 transcription factors and antagonizes BMP signaling to specify oral fate and pattern the oral-aboral axis of the mandibular arch to ensure proper formation of jaws.

    Internal states drive nutrient homeostasis by modulating exploration-exploitation trade-off

    Verónica María Corrales-Carvajal et al.
    A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.

    A new no-report paradigm reveals that face cells encode both consciously perceived and suppressed stimuli

    Janis Karan Hesse, Doris Y Tsao
    Conscious visual percepts are encoded by face patches in the absence of report, can be decoded from population recordings, and are multiplexed with the veridical physical stimulus.

    Prediction error and repetition suppression have distinct effects on neural representations of visual information

    Matthew F Tang et al.
    Multivariate analyses of human electrophysiological recordings revealed that the brain represents unexpected visual stimuli with greater fidelity than expected stimuli which arose independently of simple habituation arising from repetition.

    Human axial progenitors generate trunk neural crest cells in vitro

    Thomas JR Frith et al.
    Pluripotent stem cell differentiation provides insight into how neural crest subtypes of distinct axial identity are patterned in human embryos.

    Bichir external gills arise via heterochronic shift that accelerates hyoid arch development

    Jan Stundl et al.
    Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.
