A brain circuit linking pain and breathing may offer a path to prevent opioid deaths

Opioids can kill because they reduce breathing along with pain. Now brain scientists have made a discovery that could lead to potent pain drugs that don't affect breathing.

How your brain copes with grief, and why it takes time to heal

Grieving is a form of learning, says a scientist who studies the brain's response to loss. When someone you love dies, you have to learn new rules for navigating the world and your brain has to adapt.

Everyday tasks — such as buttoning a shirt, opening a jar or brushing teeth — can suddenly seem impossible after a stroke that affects the brain's fine motor control of the hands. New research suggests starting intensive rehab a bit later than typically happens now — and continuing it longer — might improve recovery.

The Best Time For Rehabilitation After A Stroke Might Actually Be 2 To 3 Months Later

Intensive rehabilitative therapy that starts two to three months after a stroke may be key to helping the injured brain rewire, a new study suggests. That's later than covered by many insurance plans.
