How flies dodge so fast: Brain map reveals rare synapses behind split-second escapes
Researchers at Florida Atlantic University have mapped the neural wiring of fruit flies to understand their rapid escape reflexes. The study identifies rare axo-axonic synapses that create a decentralized and resilient motor network, potentially offering insights into rapid decision-making across various species.

“researchers uncovered how rare neuron-to-neuron connections called axo-axonic synapses help fine-tune the rapid signals that drive split-second escape responses”
SINGLE SOURCE
While the general definition of axo-axonic synapses is provided by Wikipedia and PMC, the specific claim that they fine-tune rapid signals for escape responses in fruit flies is not explicitly corroborated by multiple independent sources in the provided evidence, though it is implied by the context of the FAU study results found in other claims.
