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.
Întâi am comparat diferenţele neuronale dintre o persoană depresivă şi o persoană normală, folosind scannere PET să monitorizăm fluxul sangvin. Am observat că la depresivi, în comparaţie cu cei normali, unele zone ale creierului sunt inactive, cele cu albastru.
