I graduated in 2002 from Emory as well. I would highly recommend this University to anyone considering it. I initially didn't want to go (I wanted to go to Duke), but am glad that I did. You have the CDC right down the road, as well Yerkes Primate Center (where I volunteered)....so there are tons of research oppurtunities. Some say that if a cure for AIDS is found, it is going to be at Emory (I don't know about that, but that's what people say).
I majored in Anthropology. If you get a B.S. in Anthro, they call it Anthro&Human Biology. I thought it was a great major. You get to take both science oriented courses as well as humanities in this major, which I really liked. After all, there's more to life than just science. I took classes like Evolutionary Medicine, Emerging Infectious Diseases. I even got to take a course through the Emory School of Public Health called International Health: An Anthro Perspective (I subsequently had that professor write me a rec letter!). I had a lot of friends choose NBB as their major. They all seemed to like, but I wanted something different. And some of the neuroscience courses are both Anthro and NBB classes. My advisor was Dr. Konner (MD from Harvard), who was an anthro professor and tought NBB. So there are some similarities.
The social life is nice as well. Fraternities and sororities there are pretty good, even though the Greek Life office is trying to kill them. Atlanta is a great city with lots to do.
Just make sure you like Coke and not Pepsi, because that's all you are going to see. Emory gets tons and tons of $$$$ from them.
In terms of rankings, don't buy into them too much. Emory was something like number 6 or 7 when I applied. I have no idea what it is now, but I can tell you that it is certainly one of the top universities in the nation.
