    An open-source device for measuring food intake and operant behavior in rodent home-cages

    Bridget A Matikainen-Ankney, Thomas Earnest ... Alexxai V Kravitz
    An open-source behavioral platform allows for operant, feeding, and circadian experiments in rodent home-cages.

    Organelle calcium-derived voltage oscillations in pacemaker neurons drive the motor program for food-seeking behavior in Aplysia

    Alexis Bédécarrats, Laura Puygrenier ... Romuald Nargeot
    An atypical neuronal pacemaker mechanism triggers feeding motor pattern in Aplysia..

    Hippocampus ghrelin signaling mediates appetite through lateral hypothalamic orexin pathways

    Ted M Hsu, Joel D Hahn ... Scott E Kanoski
    A communication pathway linking memory processing and feeding behavior exists between the gut hormone ghrelin, the hippocampus and the hypothalamic neuropeptide orexin.

    Transition to siblinghood causes a substantial and long-lasting increase in urinary cortisol levels in wild bonobos

    Verena Behringer, Andreas Berghänel ... Gottfried Hohmann
    In wild bonobos, sibling birth induced a sudden increase in urinary cortisol levels in the older offspring, a physiological response that occurred in all subjects and was independent of their age.

    Implications of being born late in the active season for growth, fattening, torpor use, winter survival and fecundity

    Britta Mahlert, Hanno Gerritsmann ... Sylvain Giroud
    Being born late in the active season is associated with a fast life history in a hibernating species, the garden dormouse (Eliomys quercinus).

    Tuning of olfactory cortex ventral tenia tecta neurons to distinct task elements of goal-directed behavior

    Kazuki Shiotani, Yuta Tanisumi ... Hiroyuki Manabe
    Individual neurons of ventral tenia tecta which is a part of olfactory cortex tune to specific time windows in the behavioral context during odor-guided goal-directed behaviors.
    1. Neuroscience

    Conditional chemoconnectomics (cCCTomics) as a strategy for efficient and conditional targeting of chemical transmission

    Renbo Mao, Jianjun Yu ... Yi Rao
    New toolkits have been developed to enable cell-type-specific manipulation of CCT genes with remarkable efficiency while also uncovering the role of CNMa signal in regulating morning anticipation.

    daf-16/FoxO promotes gluconeogenesis and trehalose synthesis during starvation to support survival

    Jonathan D Hibshman, Alexander E Doan ... L Ryan Baugh
    daf-16/FoxO restructures metabolism during acute starvation to promote synthesis of trehalose, which supports survival as a stress protectant and energy source.

    The effect of weight loss following 18 months of lifestyle intervention on brain age assessed with resting-state functional connectivity

    Gidon Levakov, Alon Kaplan ... Iris Shai
    Assessing predicted fMRI-based functional brain age before and after a lifestyle intervention suggests that weight loss, improved liver biomarkers, decreased liver fat, and visceral and deep subcutaneous adipose tissues correlate with attenuated brain aging.

    The Alk receptor tyrosine kinase regulates Sparkly, a novel activity regulating neuropeptide precursor in the Drosophila central nervous system

    Sanjay Kumar Sukumar, Vimala Antonydhason ... Ruth H Palmer
    The newly characterized activity regulating neuropeptide encoding gene Spar is a transcriptional target of the Jeb/Alk receptor tyrosine kinase signaling pathway in the Drosophila nervous system.
