    Shared mushroom body circuits underlie visual and olfactory memories in Drosophila

    Katrin Vogt et al.
    One memory center in the fly brain processes distinct appetitive and aversive associative memories of olfactory and visual cues using shared local circuits.

    Cannabinoid-induced actomyosin contractility shapes neuronal morphology and growth

    Alexandre B Roland et al.
    Cannabinoids inhibit neuronal expansion and growth through the rapid contraction of actomyosin.

    Neural mechanisms of economic commitment in the human medial prefrontal cortex

    Konstantinos Tsetsos et al.
    A striking dissociation exists in the medial prefrontal cortex, with different brain regions responding to value when commitments are deferred to the future and when prospects are judged to be undesirable.

    Amygdala neural activity reflects spatial attention towards stimuli promising reward or threatening punishment

    Christopher J Peck, C Daniel Salzman
    Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.

    Interpretive monitoring in the caudate nucleus

    Marianna Yanike, Vincent P Ferrera
    The caudate region of the brain signals the context in which sensory evidence is evaluated, helping animals to adapt their behavior to changing conditions.

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.

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

    Yoshinori Aso et al.
    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.

    Mechanical design principles of a mitotic spindle

    Jonathan J Ward et al.
    Precise control of microtubule architecture greatly increases the force that the spindle can exert on chromosomes.

    A neural circuit mechanism for regulating vocal variability during song learning in zebra finches

    Jonathan Garst-Orozco et al.
    By demonstrating song learning-related synaptic strengthening and pruning in the vocal control circuits of songbirds, and showing how such changes can reduce the sensitivity of the circuit to ‘noisy’ inputs, a simple neural circuit mechanism for regulating motor variability during motor skill learning is identified.

    Learning the specific quality of taste reinforcement in larval Drosophila

    Michael Schleyer et al.
    The finding that fly maggots, equipped with only 10,000 neurons, process reinforcement not only by value but also by specific quality reveals a basic operating principle of brains and challenges current models of memory organization.
