Abstract

The long-standing ambition of neuroscience to move from static maps of the brain, called connectomes, to predictive, mechanistic models of behavior, has taken a decisive step forward. Advances spanning 2024 to 2026 have transformed the complete connectome of an adult Drosophila melanogaster (fruit fly) from an anatomical achievement into a functioning, virtually embodied system. Together, these developments mark the first instance in which a fully specified animal nervous system has been rendered into a dynamic computational model capable of generating behavior. In this News and Views article, we briefly review these fascinating developments and their scientific, technological and philosophical implications.
