    PDF-1 neuropeptide signaling regulates sexually dimorphic gene expression in shared sensory neurons of C. elegans

    Zoë A Hilbert, Dennis H Kim
    Sex-specific neuropeptide signaling in the shared sensory nervous system regulates sexually dimorphic gene expression and male-specific behavior in C. elegans.
    1. Neuroscience

    Sexually dimorphic neuronal responses to social isolation

    Laura Senst et al.
    Male and female mice react differently to social isolation but not to an acute physical stress.
    1. Neuroscience

    Dopaminergic and opioidergic regulation during anticipation and consumption of social and nonsocial rewards

    Sebastian Korb et al.
    Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).
    1. Neuroscience

    Transient oxytocin signaling primes the development and function of excitatory hippocampal neurons

    Silvia Ripamonti et al.
    Perturbation of oxytocin signaling causes alterations that may be causally involved in the etiology of oxytocin-related neurobehavioral disorders.
    1. Neuroscience

    Relaxation of synaptic inhibitory events as a compensatory mechanism in fetal SOD spinal motor networks

    Pascal Branchereau et al.
    Electrophysiological and simulation approaches show that a chloride-related longer relaxation of the inhibitory synaptic events partially compensates the early defect in the chloride homeostasis detected in fetal SOD spinal motoneurons.

    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.

    The adipocyte hormone leptin sets the emergence of hippocampal inhibition in mice

    Camille Dumon et al.
    Maternal obesity and excess of the adipocyte hormone leptin delays the emergence of synaptic inhibition in the developing brain mice.
    1. Developmental Biology

    Developmental evolution of the forebrain in cavefish, from natural variations in neuropeptides to behavior

    Alexandre Alié et al.
    A comparative approach shows that developmental evolution of neuropeptidergic neuronal groups in the hypothalamus of blind cavefish drives adaptive behavioral evolution.
    1. Neuroscience

    Oxytocin signaling in the medial amygdala is required for sex discrimination of social cues

    Shenqin Yao et al.
    Oxytocin signaling plays a critical role in a molecularly defined neuronal population of the Medial Amygdala to modulate the behavioral and physiological responses of male mice to females on a moment-to-moment basis.
