Lighting up the brain
So far, 295 individual neurons have been reconstructed and mapped into this framework.
Mapping the neurons
Here, the images shows the individual neuronal connections as mapped into the CCF.
A common framework
The process will continue for the remaining neurons in the brain. Scientists estimate there are about 14 million neurons in the mouse cortex and about 70 million in the entire mouse brain. Here, the ones mapped so far so up like specks on the brain.

The process requires painstaking effort to map the stunningly intricate detail in the mouse brain. However, the current progress is just a small step on the road toward mapping a human brain.
Here, another view of the mouse brain as depicted in the Mouse Common Coordinate Framework, which can be freely accessed by researchers at brain-map.org
