If you made a list of things that could advance the field of science, having a mouse watch “The Matrix” and “Star Wars” probably wouldn’t make it to the top. And yet, scientists recently were able to map and render into a 3D atlas a small portion of a mouse’s brain about the size of a grain of sand. The results were a revelation. “"A millimeter seems small, but within that millimeter there are kilometers of wiring," Jacob Reimer, a neuroscientist at Baylor College of Medicine said.

"They managed to do something that we haven’t done as a neuroscience community in basically all of our history, which is to be able to map the activity of neurons onto the wiring on a very large population of neurons."

I started researching this topic with unbridled (and apparently unfounded) optimism, hoping to highlight an example of a public health problem that we handled so well. Instead, I found a bit of a mixed bag: we made quite a bit of progress in handling lead pollution and still managed to fall short.

"Researchers have created the largest and most detailed wiring diagram of a mammalian brain to date, by mapping cells in a cubic millimetre of a mouse’s brain tissue. In a landmark achievement, the diagram also details the activity of individual neurons on a large scale ― a neuroscience first."
