    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.

    From behavior to circuit modeling of light-seeking navigation in zebrafish larvae

    Sophia Karpenko et al.
    Light-seeking strategies in Zebrafish larvae are dissected using a virtual-reality assay, and these data are used to establish minimal stochastic and neural-circuits models that quantitatively capture this behavior.

    Modulation of flight and feeding behaviours requires presynaptic IP3Rs in dopaminergic neurons

    Anamika Sharma, Gaiti Hasan
    Motivation for flight and feeding behaviour requires dopamine release which depends on cholinergic stimulation and intracellular Ca2+ release from ER stores in one or two pairs of central dopaminergic neurons.

    BiteOscope, an open platform to study mosquito biting behavior

    Felix JH Hol et al.
    A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.

    Sex-specific effects of cooperative breeding and colonial nesting on prosociality in corvids

    Lisa Horn et al.
    A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
