By October 2024, the full map has been completed. This seem to a just science-fiction a few years ago.
The whole-brain map, traced over years with painstaking precision, is tiny but exquisite: It holds 149.2 meters of neural wiring, all tidily packed into a brain about the size of a poppy seed. As such, this map shows how neural information might flow among cells in Drosophila melanogaster, an animal that’s simpler than a human but complex enough to remain mysterious to people trying to understand its brain.
The first full map of fruit fly’s brain charted 139,255 nerve cells and their millions of connections.
A new map of the full Drosophila brain reveals the 50 largest neurons. These behemoths and their thin cellular projections are each a different color.
Already, the data have proven their utility, revealing cellular details and juicy hints about how brains work. For instance, there are only two CT1 neurons in the whole fly brain, each of which is involved with sensing changes in light and motion. Each neuron stretches across an entire eye and makes a massive number of synapses — more than 148,000, the map shows.
Neuroscientist Olaf Sporns says - “I foresee a future where connectome maps will become even more comprehensive and detailed, soon to include brains of vertebrates like mouse and human,”
Those maps will help answer big questions about brain connectomes — whether they’re variable among individuals, if they change over time, and whether they can help predict behaviors.
