Interesting. I've stumbled over this when I was writing a piece on depression:
Physiological activity of the brain. Cutting-edge research also suggest that moods and thoughts are influenced not only by neurotransmitter and hormones but also by the cellular activity of various parts of the brain. The activity of particular areas of the brain can now be studied by measuring the rate of blood flow or energy metabolism; modern techniques permit areas as small as the nail on your little finge. to be visualized. Depressed persons often have decreased blood flow to several areas in their brain, especially the frontal regions. Brain activity appears to be shifted to other areas of the brain involved in processing emotional arousal. These changes may also be accompanied by a relative increase in the activity of the nondominant side of the brain (usually the right). Taken together, these changes in brain activity might explain why some depressed people seem to be virtually unable to use good advice or standard problem-solving strategies to reduce their difficulties. It is as if an arousal circuit of the brain is stuck in the "on" position and deactivates other, more complex circuits.
