    Changes to social feeding behaviors are not sufficient for fitness gains of the Caenorhabditis elegans N2 reference strain

    Yuehui Zhao et al.
    Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

    Drosophila mushroom bodies integrate hunger and satiety signals to control innate food-seeking behavior

    Chang-Hui Tsao et al.
    Mushroom bodies are a hunger and satiety integrative center that controls food-seeking behavior in Drosophila..

    optoPAD, a closed-loop optogenetics system to study the circuit basis of feeding behaviors

    José-Maria Moreira et al.
    The optoPAD system combines real-time behavioral analysis with optogenetic manipulations to study how animals adapt to dynamic gustatory environments and to identify the circuit basis of feeding.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    Freezing suppression by oxytocin in central amygdala allows alternate defensive behaviours and mother-pup interactions

    Elizabeth Rickenbacher et al.
    Oxytocin in the amygdala suppresses freezing of mothers when exposed to a threat in the presence of their offspring, allowing for pup protection and transmission of information about danger from mothers to pups.

    An opioid-like system regulating feeding behavior in C. elegans

    Mi Cheong Cheong et al.
    The discovery that opioid neuropeptide neuronal signaling controls feeding behavior in a genetically tractable invertebrate model may help unravel the mechanisms of appetite control in humans.

    Closed-loop optogenetic activation of peripheral or central neurons modulates feeding in freely moving Drosophila

    Pierre-Yves Musso et al.
    The Sip-Triggered Optogenetic Behavior Enclosure (STROBE) produces robust behaviors via activation of peripheral or central neurons in the fly, and mimics key features of feeding driven by chemical taste ligands.
    1. Neuroscience

    Ventral pallidal encoding of reward-seeking behavior depends on the underlying associative structure

    Jocelyn M Richard et al.
    Reward-related cues elicit phasic changes in activity in ventral pallidum neurons, which predict and functionally contribute to the speed of behaviors trained on the basis of act-outcome, but not stimulus-outcome, contingencies.

    Folding behavior of a T-shaped, ribosome-binding translation enhancer implicated in a wide-spread conformational switch

    My-Tra Le et al.
    Folding and unfolding pathways are described for a ribosome-binding 3' cap-independent translation enhancer at the center of a conformational rearrangement that is implicated in the transition from translation to replication of an RNA virus.

    Maternal Behavior: Why mother rats protect their children

    Ksenia Z Meyza, Ewelina Knapska
    The presence of the hormone oxytocin in the central amygdala makes a mother rat willing to put her life in danger in order to protect her offspring.
