This color-coded graphic shows different populations of cells in the mouse brain, each one targeted by one of the genetic tools developed by scientists at the Allen Institute and other institutions.

Most of the time, you assume your brain is either “on” or “off,” awake or asleep. A new study shows something far more intricate. Deep inside the skull, entire networks of cells quietly hand off ...

In a scientific first, researchers from around 29 universities and institutions across North America have teamed up to create a large, versatile, and effective arsenal of new biological tools that ...

Scores of researchers have produced new tools that can deliver genes and selectively activate them in hundreds of different cell types in the brain and spinal cord, a breakthrough that scientists hope ...
