Brain breakthrough: Dopamine doesn't work at all like we thought it did
Dopamine doesn’t flood the brain as once believed – it fires in exact, ultra-fast bursts that target specific neurons. The discovery turns a century-old view of dopamine on its head and could transform how we treat everything from attention-deficit/hyperactivity disorder (ADHD) to Parkinson’s…

I studied parts of the basal ganglia, part of the dopaminergic circuits of motor control. I'm not sure if it's a poorly written (news) article or the scientist was overstating his position - I don't know any neuroscientists who think dopamine is "sprayed" across the brain.
Edit: The paper is a breakthrough because it's reporting the first-ever direct imaging of dopamine signaling. But the news article mischaracterizes it.
