    The alternative regenerative strategy of bearded dragon unveils the key processes underlying vertebrate tooth renewal

    Lotta Salomies, Julia Eymann ... Nicolas Di-Poï
    Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.

    Constructing an adult orofacial premotor atlas in Allen mouse CCF

    Jun Takatoh, Jae Hong Park ... Fan Wang
    A new three-step monosynaptic premotor tracing strategy in adult mice, together with registration to the Allen mouse common coordinate framework, uncovered precise spatial relationships of distinct orofacial premotor circuits in the brainstem.

    Target-specific membrane potential dynamics of neocortical projection neurons during goal-directed behavior

    Takayuki Yamashita, Carl CH Petersen
    A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.

    An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates

    Alexandre P Thiery, Ariane SI Standing ... Gareth J Fraser
    The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

    Foxc1 establishes enhancer accessibility for craniofacial cartilage differentiation

    Pengfei Xu, Haoze V Yu ... J Gage Crump
    Foxc1 proteins prepare the genomes of neural crest-derived cells to facilitate their later development into the cartilages that support the embryonic face.

    Structural basis of transcription inhibition by the DNA mimic protein Ocr of bacteriophage T7

    Fuzhou Ye, Ioly Kotta-Loizou ... Xiaodong Zhang
    DNA mimicry Ocr protein, a well-studied T7 phage protein that inhibits host restriction enzymes, can also inhibit host transcription through competing with sigma factors in binding to RNA polymerase.

    Giant extinct caiman breaks constraint on the axial skeleton of extant crocodylians

    Torsten M Scheyer, John R Hutchinson ... Marcelo R Sánchez-Villagra
    The giant caiman Purussaurus from the Miocene of Venezuela is the first recorded member of crown Crocodylia having three sacrals, thus breaking the otherwise strict vertebral constraint of the group.

    The satiety hormone cholecystokinin gates reproduction in fish by controlling gonadotropin secretion

    Lian Hollander-Cohen, Omer Cohen ... Berta Levavi-Sivan
    Genetic loss-of-function approaches and functional calcium imaging reveal cholecystokinin as the primary regulator of follicle-stimulating hormone in zebrafish, redefining our understanding of gonadotropin regulation in vertebrates.

    Characterization of cephalic and non-cephalic sensory cell types provides insight into joint photo- and mechanoreceptor evolution

    Roger Revilla-i-Domingo, Vinoth Babu Veedin Rajan ... Kristin Tessmar-Raible
    Molecular, cellular and behavioral genetic approaches in Platynereis dumerilii indicate that r-Opsins can act as ancient, light-dependent modulators of mechanosensation, and suggest that light-independent mechanosensory roles of r-Opsins evolved secondarily.

    Impact of precisely-timed inhibition of gustatory cortex on taste behavior depends on single-trial ensemble dynamics

    Narendra Mukherjee, Joseph Wachutka, Donald B Katz
    Primary taste cortex does far more than code tastes by turning taste codes into motor commands via population dynamics.
