Like humans, dolphins have large brains and a complex social structure. In this Nova documentary, Private Lives of Dolphins, we see footage of behavior never witnessed before. While the privacy of dolphins at research stations in Florida and Australia may not be as secluded as in the open seas, we do get a glimpse of their behavior in the wild. In addition, the dolphin's relationship with humans is closely examined. This fascinating study of the dolphin's intelligence, and their interactions with both their own kind and with us, furnishes the viewer with a unique insight into the development of the mammalian brain.

Brain Transplant is a continuation of the 1986 Nova presentation The Case of the Frozen Addict. In the earlier film, drug users were stricken with a strange illness and became paralyzed or "frozen."

In this update, Nova follows two afflicted addicts to Sweden where they receive treatment unavailable in the U.S. Other treatments are discussed, including L-dopa and adrenal cell transplants. The ethics of fetal tissue research are also debated.
