    Drosophila neprilysins control insulin signaling and food intake via cleavage of regulatory peptides

    Benjamin Hallier et al.
    The catalytic activity of a Drosophila neprilysin is critical to proper insulin expression and food intake by regulating homeostasis of distinct signaling peptides.

    Light reintroduction after dark exposure reactivates plasticity in adults via perisynaptic activation of MMP-9

    Sachiko Murase et al.
    Light reintroduction (LRx) after dark exposure reactivates structural and functional plasticity in the adult mouse visual cortex by increasing the activity of MMP-9 at thalamo-cortical synapses.

    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 rate of transient beta frequency events predicts behavior across tasks and species

    Hyeyoung Shin et al.
    Across species, tasks and recording modalities, the rate of transient neocortical beta frequency (15-29Hz) events strongly predicts perceptual ability, providing fundamental mechanistic insight, with implications for tracking and manipulating brain dynamics.

    A microRNA negative feedback loop downregulates vesicle transport and inhibits fear memory

    Rebecca S Mathew et al.
    A fear conditioning-induced miRNA acts in a negative feedback loop that targets vesicle exocytosis and neurotransmitter receptor trafficking, and inhibits memory formation.

    Intramuscular Neurotrophin-3 normalizes low threshold spinal reflexes, reduces spasms and improves mobility after bilateral corticospinal tract injury in rats

    Claudia Kathe et al.
    Delayed intramuscular gene therapy with neurotrophin-3 after corticospinal tract injury reduces spasticity and improves locomotion by treating underlying causes of spasticity.

    Arcuate hypothalamic AgRP and putative POMC neurons show opposite changes in spiking across multiple timescales

    Yael Mandelblat-Cerf et al.
    Gradual changes in the firing of specific hypothalamic neurons over many hours signal falling energy levels, while short-lived changes over seconds and minutes signal the availability of food.

    Altered paracrine signaling from the injured knee joint impairs postnatal long bone growth

    Alberto Roselló-Díez et al.
    Genetic analyses in mice reveal a communication system between the knee joint and the developing bones that could be explored in studies addressing evolutionary changes in body proportions and in future therapies for growth disorders.

    Oxytocin functions as a spatiotemporal filter for excitatory synaptic inputs to VTA dopamine neurons

    Lei Xiao et al.
    Oxytocin, a peptide linked to the processing of socially meaningful stimuli, modulates excitatory synaptic transmission in dopaminergic neurons of ventral tegmental area via retrograde endocannabinoid signaling, acting as a pathway-specific temporal filter for synaptic inputs.

    Shared rhythmic subcortical GABAergic input to the entorhinal cortex and presubiculum

    Tim James Viney et al.
    GABAergic parvalbumin-expressing 'orchid cells' of the medial septum selectively target GABAergic neurons in connected extra-hippocampal areas of the mouse, providing rhythmically bursting inhibitory input at the peak of hippocampal 5-12 Hz theta oscillatory cycles.
