Maybe you got the exact toy you wanted for your birthday and you were really happy. Or your friend is sick and you feel sad. Or your little brother messed up your room, so you're really angry! Where do those feelings come from? Your brain, of course. Your brain has a little bunch of cells on each side called the amygdala (say: uh-MIG-duh-luh).
Kodiak Island. Kodiak Island (Alutiiq: Qikertaq, Russian: ÐºÐ°Ð´ÑÑÐºÑ) is a large island on the south coast of the U.S. state of Alaska, separated from the Alaska mainland by the Shelikof Strait.

Cut off from the mainland for the last 12,000 years, Kodiak Island is something close to paradise for bears. Two-thirds of the island is a national wildlife refuge, and the human population is low enough (around 13,000) that the bears face very few natural threats or competition for food.
