english: So the first thing we did was, we compared, what's different in the brain of someone with depression and someone who is normal, and what we did was PET scans to look at the blood flow of the brain, and what we noticed is that in patients with depression compared to normals, areas of the brain are shut down, and those are the areas in blue.

Uradili smo PET skeniranje da bismo videli protok krvi u mozgu i primetili smo da su kod pacijenata sa depresijom, u poređenju sa normalnima, neki delovi mozga isključeni, i to su ove oblasti plave boje.
