Abstract

The catecholamines play a major role in the regulation of behavior. Here we investigate, in the fly Drosophila melanogaster , the role of dopamine and octopamine (the presumed arthropod homolog of norepinephrine) during the formation of appetitive and aversive olfactory memories. We find that for the formation of both types of memories, cAMP signaling is necessary and sufficient within the same subpopulation of mushroom-body intrinsic neurons. On the other hand, memory formation can be distinguished by the requirement for different catecholamines, dopamine for aversive and octopamine for appetitive conditioning. Our results suggest that in associative conditioning, different memories are formed of the same odor under different circumstances, and that they are linked to the respective motivational systems by their specific modulatory pathways.

  • Hebbian-like plasticity in connections at the output of the mushroom body can support various forms of reinforcement learning.

    “It is well established that Hebbian-like plasticity in connections at the output of the mushroom body can support various forms of reinforcement learning [71,76–78].”

    From Phenomenal interface theory: a model for basal consciousness (2025) · cites this paper as [76]

    The Discussion (page unavailable) reports that both sugar-reward and electric-shock olfactory memories involve plasticity in mushroom-body Kenyon cells and tentatively locates it at their output synapses. The paper does not establish that this plasticity is Hebbian-like; it describes the output-synapse mechanism as tentative rather than well established. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
