    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.

    Persistent activity in a recurrent circuit underlies courtship memory in Drosophila

    Xiaoliang Zhao et al.
    Persistent activity of dopaminergic neurons in a mushroom recurrent circuit lays the foundation for courtship memory in Drosophila.

    Multiple neurons encode CrebB dependent appetitive long-term memory in the mushroom body circuit

    Yves F Widmer et al.
    The transcription factor CrebB mediates long-term memory formation in different neurons within the mushroom body learning circuit, including mushroom body intrinsic and output neurons but not dopaminergic input neurons.

    Dismantling the Papez circuit for memory in rats

    Seralynne D Vann
    In contrast to current models, inputs from midbrain limbic structures, but not from the hippocampus, are necessary for mammillary body contributions to memory.
    1. Neuroscience

    Medial entorhinal cortex activates in a traveling wave in the rat

    J Jesús Hernández-Pérez et al.
    The existence of traveling waves in the medial entorhinal cortex, like those observed in the hippocampus, supports the hypothesis that traveling waves coordinate the activity of anatomically distributed circuits.

    The neuronal architecture of the mushroom body provides a logic for associative learning

    Yoshinori Aso et al.
    A map of the entire array of cell types and potential projections in the mushroom body of the fruit fly brain provides insights into the circuitry that supports learning of stimulus-reward and stimulus–punishment associations.
    1. Neuroscience

    Reciprocal synapses between mushroom body and dopamine neurons form a positive feedback loop required for learning

    Isaac Cervantes-Sandoval et al.
    Structural and functional analysis of axonal-axonal reciprocal connections between dopamine neurons and Kenyon cells provides insight into the brain computations for normal associative olfactory learning.
    1. Neuroscience

    Direct neural pathways convey distinct visual information to Drosophila mushroom bodies

    Katrin Vogt et al.
    Building on previous work (Vogt et al. 2014), separate visual pathways have been identified to convey information for brightness and color to the learning-related area of the Drosophila brain.
    1. Neuroscience

    A single pair of neurons links sleep to memory consolidation in Drosophila melanogaster

    Paula R Haynes et al.
    Dorsal paired medial neurons, which are required for memory consolidation, promote sleep by inhibiting the excitation of mushroom body neurons.
    1. Neuroscience

    A role for descending auditory cortical projections in songbird vocal learning

    Yael Mandelblat-Cerf et al.
    Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.
