Brian Moore is one of the people who has volunteered a couple of times for Helen Neville’s language fMRI studies at the University of Oregon. Find out why in this video clip.

We started in the morning with what turned into a rather chaotic fMRI scene -- six people in two locations. And the magnetism of the equipment made filming complicated.

Larry Engel, Director and Director of Photography for "The Human Spark," shares his initial thoughts on his task of filming Alan Alda.

Alan Alda gives an introduction to "The Human Spark," a new series that explores the question, "What makes us human?"

Graham Chedd tells the story of what happened at the European Synchrotron Radiation Facility, where researchers were examining Neanderthal teeth with a high-power x-ray.

While we can manipulate elaborate equations with square roots and derivatives, new research shows monkeys can “count” audible beeps and equate them to visual representations of the same amount.

How long did it take Neanderthals to grow up? Graham Chedd meets with researchers who are using a giant particle accelerator to find an answer to this question.
