Neuroscience Breakthrough: Entire Brain of Adult Fruit Fly Mapped

The open map covers nearly 140,000 neurons and 50 million synapses, and researchers say it could help explain behavior and brain disease.

Summary by Science Daily
Scientists have made an enormous step toward understanding the human brain by building a neuron-by-neuron and synapse-by-synapse roadmap -- scientifically speaking, a 'connectome' -- through the brain of an adult fruit fly (Drosophila melanogaster). Previous researchers have mapped the brain of a C. elegans worm, with its 302 neurons, and the brain of a larval fruit fly, which had 3,000 neurons, but the adult fruit fly is several orders of magni…

Using dopamine and artificial neurons Google recently announced that they had successfully created a complete 3D map of a fruit fly's brain and nervous system. It wasn't long before some amazing people managed to get the digital model of the brain to learn how to play a modded version of DOOM. A software engineer connected the fly's brain to the game and by letting the game's frames stimulate the fly's neurons and using dopamine as a "reward" f…

Scientists have mapped more than 166,000 neurons and 125 million synaptic connections in an adult male fruit fly. The AI-generated connectome offers new insights into how the brain works.

Scientists from Google and Janelia mapped the entire 166,000 brain neurons of a male Drosophile. This absolute 3D connectome explains gender-related behaviours, opening up dizzying perspectives to decipher the human mind and certain neurological conditions.
