...When a hungry person is hit with such multisensory stimuli, it's no surprise that the brain starts screaming chow time, and the PET scan showed that it was screaming loudly. Appetite and hunger are processed in a lot of regions - most notably the orbital frontal cortex, which is linked to self-control; the striatum, which is linked to motivation; the hippocampus, which is linked to memory; and the amygdala, which is linked to powerful emotions. In Wang's subjects, all these regions were ringing the dinner bell...
...rank each on a 1-to-10 scale. The researchers then selected one food for each subject, the only requirement being that it scored 7 or above in desirability. When the 17 hours were up, the volunteers were injected with a nuclear tracer, placed in a brain-imaging PET scanner and presented with a food they craved. Actually, they were more than merely presented with...
...Wang then told his volunteers to do what few mortal people could do: think about something else. For the next 40 minutes, while the PET scanner hummed, the subjects fought to close their minds to the thoughts of food in any way they could, though they were required to keep their eyes open. "We tried to make it a real-life experience," says Wang. "It's like being in a buffet line, only it lasts a lot longer." (See the top 10 food trends...
...Wang is not certain what's behind the differences, though he suspects hormones may play a significant role. He did get a better sense of the areas of the brain those hormones affect most, owing to the fact that he used a long-running PET scan rather than a shorter session with a functional magnetic resonance imager (fMRI), which is how such studies are usually conducted. This afforded him a good look at the amygdala, the deepest and most primitive of the brain structures involved. When the amygdala acts up, it's exceedingly hard to bring it to heel...
...plot is a massive indulgence of the desire to adopt with abandon that generally happens when children visit a shelter. With the help of young pet-store employee Dave (Johnny Simmons), who provides discounted kibble and makes Andi's heart beat faster, his sassy sidekick Heather (Kyla Pratt) and a neighborhood kid (Troy Gentile), Andi and Bruce are soon actively recruiting stray dogs. The movie shifts into slapstick mode, much of it centered on the dining and bathroom habits of the hundred or so newly arrived hotel guests...
