Abstract

Spatial maps in the brain are most accurate when they are linked to external sensory cues. Here, we show that the compass in the Drosophila brain is linked to the direction of the wind. Shifting the wind rightward rotates the compass as if the fly were turning leftward, and vice versa. We describe the mechanisms of several computations that integrate wind information into the compass. First, an intensity-invariant representation of wind direction is computed by comparing left-right mechanosensory signals. Then, signals are reformatted to reduce the coding biases inherent in peripheral mechanics, and wind cues are brought into the same circular coordinate system that represents visual cues and self-motion signals. Because the compass incorporates both mechanosensory and visual cues, it should enable navigation under conditions where no single cue is consistently reliable. These results show how local sensory signals can be transformed into a global, multimodal, abstract representation of space.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ring neurons cluster into different types that encode the position of different orientation cues.

    “Ring neurons also cluster into different types which seem to encode the position of different orientation cues [15,17].”

    From A model of cue integration as vector summation in the insect brain (2023) · cites this paper as [17]

    The Discussion (‘R neurons connect the compass to the sensory environment’; page unavailable) reports 11 morphological R-neuron types and says characterized R neurons encode sensory cues related to the fly’s angular position. It specifically finds that both R1 and R3a encode wind direction, but does not establish that different types encode different kinds of orientation cue. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Visual and mechanosensory cues reach the ring neurons in flies, and visual input is confirmed in dung beetles.

    “Both visual and mechanosensory cues are known to reach the ring neurons in flies [17], with visual input also being confirmed in dung beetles [27].”
  • Hebbian learning is often suggested for the construction of R→E-PG mappings.

    “Hebbian learning is often suggested for the construction of R → E-PG mappings [16,17,19,20,28,41]).”
  • None of the individual elements in the model presented are new.

    “Conceptually, none of the individual elements in the model we present are new [8,13,17,21,41].”

    From A model of cue integration as vector summation in the insect brain (2023) · cites this paper as [17]

    The Results section describes this paper’s model of how wind signals reach compass neurons, providing a possible precedent for an element of the citing authors’ model. But the citing sentence does not identify its individual elements, and no passage in our copy establishes that all of them were already known. I searched the modeling results and discussion for a statement about the novelty of those elements. (LLM, conf=0.72)

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.
