    Reward signal in a recurrent circuit drives appetitive long-term memory formation

    Toshiharu Ichinose et al.
    A recurrent reward circuit in Drosophila, comprised of specific dopamine neurons and a single class of mushroom body output neurons, transforms a nascent memory trace into a stable long-term memory.
