  • Episode Description
  • How does a brain work? When does the structure of a brain produce true intelligence? What is the relationship between brain size and behavior. How are libraries an extension of our brains? In this installment, Dr. Sagan discusses the human brain, guiding the viewer through a maze of a brain model to demonstrate the intricacies of thought. He compares the intelligence of a whale to that of a human, and offers an explanation of how all the information needed for survival is stored in human genetic material and brains, and in books.moreless
