Researchers at the Allen Institute for Brain Science, a Seattle nonprofit dedicated to neuroscience, have made a 3D map trace that can cover about 100 million brain cells. They hope the map will bring that understanding to a new level, the Allen Institute said. In doing so, neuroscientists will have a tool with which to develop new research programs and accelerate research already underway. They also did a lot better than the last time they tried.There are 2 reasons why they did it.
First of all, they got The result comprises an “average” of the brains of 1,675 laboratory mice, to make sure the map was as standard as possible. And Mice are common “model organisms” in neuroscience. Their brains have fairly similar structures to humans’, they can be trained, they breed easily, and researchers have already developed robust understandings of how their brains work.
second, they traced connections between brain cells using thin slices of tissue that can be imaged and explored layer by layer. To build a comprehensive, three-dimensional map, the Allen Institute team instead broke the mouse brain into “voxels” — 3D pixels — and then mapped the cells and connections within each voxel.
After all, the two points that I said was why they succeeded. However, as time passes I think they can do better.
