Google and HHMI Release Complete Map of Male Fruit Fly Brain, Elucidating 166,000 Neuronal Connections via AI

Google Research, HHMI Janelia, and collaborating researchers have released the first complete brain map mapping the entire brain and central nervous system of the male fruit fly, a key model organism in science. This project was established through years of research and is intended to serve as foundational data for understanding how sensory inputs are converted into movement and behavior.

The research team used Artificial Intelligence (AI) technology to reconstruct complex neural pathways, thereby documenting all neural connections in the adult male fruit fly brain. This mapping includes over 166,000 neurons and approximately 12,000 distinct cell types.

Elucidating Brain Structure Differences by Sex

This study reveals key differences in how female and male fruit fly brains process information. These findings provide an important foundation for setting the future direction of neuroscience and brain research.

The research results can be verified on the Neural Mapping website through 5 new visualizations and 3 companion studies, contributing to the advancement of neuroscience understanding.
