New imaging method shows how genes activate in the living brain

For the first time, scientists have figured out how to view changes to gene activity in living brains. The brain scan technique may aid discoveries in how Alzheimer’s treatments, schizophrenia, and other neurological disorders work. And not just that: this approach may also help scientists evaluate whether drugs work the way they’re supposed to.
The researchers focused on molecules that regulate how tightly DNA wraps around the proteins that serve as structural units for our genetic
