We know the brain changes after traumatic injury, and now we have maps from mice showing what that change looks like.

A team of scientists has traced connections between nerve cells throughout the entire brain of mice, showing that distant parts of the brain become disconnected after a head injury.

The stunning visualizations of brain-wide connectivity could help scientists understand how a traumatic brain injury, or TBI, alters cross-talk between different cells and brain regions, first in mice and then in humans.
