Google helps publish the largest high-res map of brain connectivity
It's 'just' for a fruit fly, but it still represents a major milestone

A joint effort between Google and the Janelia Research Campus has just achieved a significant breakthrough in brain mapping. They've published the largest high-resolution map of brain connectivity to date, offering a 3D model of 25,000 fruit fly neurons across a diverse range of cell types and multiple brain regions.

The brain map won't accomplish much by itself. However, it could prove to be a treasure trove of data for scientists looking to understand fruit flies in particular or brain functionality at large.

Even as large as this map is, it represents just a quarter of the 100,000 neurons in a typical fruit fly. Most larger species' brains are considerably more complex, and a human's 86 billion neurons would take much, much more work to map correctly. This is an important moment, but it's ultimately a stepping stone.

The most complete brain map ever is here: A fly’s “connectome“

It took 12 years and at least $40 million to chart a region about 250µm across
“It’s a landmark,” says Clay Reid, a neuroscientist at the Allen Institute in Seattle who has been working to create a similar map for a cubic millimeter of mouse brain.
