Scene 2 (16s)
Principles in motivational and emotional brain research Specific brain structures generate specific motivational states. e.g., hypothalamus hunger Biochemical agents stimulate these brain structures. e.g., ghrelin —Y bloodstream -+ hypothalamus Day-to-day events stir biochemical agents into action. e.g., dieting & sleep deprivation -+ t ghrelin & I leptin.
Scene 3 (32s)
Environ- mental event Food deprivation (i.e., dieting) Biochem -ical agent Ghrelin (a hormone) produced and circulated in the bloodstream Brain struct- ure Ghrelin stimulates hypothalmus Aroused motivati on Stimulated hypothalamus creates the psychological experience o hunger.
