# Researchers publish first complete connectome of fruit fly brain and 'spinal cord'

> **Open Intelligence Dossier** · First detected: 2026-06-15 04:07 UTC · Category: Science

## Executive Summary
Researchers have successfully mapped the complete neural circuitry of an adult fruit fly, detailing over 139,000 individual neurons.

## Intelligence Brief
Scientists have released the first comprehensive connectome of the adult fruit fly brain and its associated nerve cord. This map delineates every neural connection present within the specimen, totaling 139,225 neurons.


Coverage from outlets including EurekAlert!, Scientific Frontline, ScienceDaily, 동아사이언스, Harvard Medical School, and Phys.org emphasizes the scale of the mapping project known as Flywire. Reports highlight that the process yielded unexpected findings regarding the insect's neural architecture.


Future developments will depend on how this structural data is utilized by the scientific community to analyze neural pathways. Coverage does not yet specify the long-term applications of this mapping for broader neurological research.
