    The transcription factor NRSF contributes to epileptogenesis by selective repression of a subset of target genes

    Shawn McClelland, Gary P Brennan ... Tallie Z Baram
    Uncovering the mechanisms by which the transcription factor NRSF contributes to the development of epilepsy reveals that the regulation of gene expression by transcription factors in the brain is more finely-tuned than previously thought.

    Mushroom body output neurons encode valence and guide memory-based action selection in Drosophila

    Yoshinori Aso, Divya Sitaraman ... Gerald M Rubin
    Output neurons in the mushroom body of the fruit fly brain encode the positive or negative survival value of stimuli, enabling insects to choose adaptive approach and avoidance behaviors through associative learning.

    Increasing Notch signaling antagonizes PRC2-mediated silencing to promote reprograming of germ cells into neurons

    Stefanie Seelk, Irene Adrian-Kalchhauser ... Rafal Ciosk
    Increased Notch signaling enhances germ cell reprograming in C. elegans by antagonizing PRC2-mediated repression, which results in the activation of UTX-1 and other reprograming-promoting genes.

    Neural circuitry coordinating male copulation

    Hania J Pavlou, Andrew C Lin ... Stephen F Goodwin
    A circuit consisting of motor neurons, inhibitory interneurons and mechanosensory neurons controls copulatory behaviour in male fruit flies.

    Long-range projection neurons in the taste circuit of Drosophila

    Heesoo Kim, Colleen Kirkhart, Kristin Scott
    Taste pathways to higher brain are critical for learned responses to taste compounds.

    FlpStop, a tool for conditional gene control in Drosophila

    Yvette E Fisher, Helen H Yang ... Thomas R Clandinin
    FlpStop is a generalizable tool for conditional gene disruption and rescue and enables critical experiments examining the interactions between genes, circuits, and computation.

    Genetic and neuronal regulation of sleep by neuropeptide VF

    Daniel A Lee, Andrey Andreev ... David A Prober
    Genetic experiments in zebrafish identify neuropeptide VF (NPVF) signaling and NPVF-expressing neurons as a novel vertebrate hypothalamic sleep-promoting system that is functionally conserved with invertebrates.

    Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

    Kathrin Steck, Samuel J Walker ... Carlos Ribeiro
    Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.

    Sensorimotor pathway controlling stopping behavior during chemotaxis in the Drosophila melanogaster larva

    Ibrahim Tastekin, Avinash Khandelwal ... Matthieu Louis
    The reconstruction of a sensorimotor pathway from the olfactory-sensory neurons down to the pre-motor system reveals a descending neuron that plays a critical role in the organization of larval chemotaxis.

    Temporally specific engagement of distinct neuronal circuits regulating olfactory habituation in Drosophila

    Ourania Semelidou, Summer F Acevedo, Efthimios MC Skoulakis
    Habituation to brief olfactory stimulation is biphasic and mediated by distinct neuronal circuits where an initial latency phase is rapidly followed by stimulus devaluation signifying behavioral habituation in Drosophila.
