Michał Januszewski and Viren Jain write that researchers have released a complete wiring diagram of the male fruit fly's brain and central nervous system, marking it as the largest brain map to date. In collaboration with HHMI Janelia, this project utilized computing and advanced techniques to create an annotated cellular-scale map containing over 166,000 neurons and 125 million synaptic connections. This foundational resource aims to help scientists understand how nervous systems function and may eventually assist in understanding complex human brain processes like memory or disease.
- The connectome includes the ventral nerve cord, which functions similarly to a spinal cord.
- Researchers are using similar mapping techniques on vertebrates, including fish and mice.
- This map complements previously released female fruit fly connectomes, allowing for studies of sexual dimorphism in behavior like courtship or aggression.

Researchers have completed the first comprehensive wiring map of an adult fruit fly's central nervous system, linking neurons from the brain to those in the body through the nerve cord. The findings suggest that motor control is largely organized into distributed local circuits within specific body parts rather than being directed by a single centralized command center in the brain. This breakthrough allows scientists to trace information flow across an entire nervous system, moving from sensory perception to physical action.
- Mapping of every connection between neurons in the brain and nerve cord
- Discovery of decentralized motor control via local neural modules
- Ability to observe how sensation translates into movement holistically
