"Frontiers has taken me to some extraordinary places - physically and intellectually. We've hunted fundamental particles in a Canadian nickel mine, heard how all Chinese folk have perfect pitch and seen how the New World was once populated by Monster Wombats and Mega-Wolves. What fascinates me about this series, though, is the scientists themselves creatively reaching into the mists of unexplored fields, sometimes coming up with some frankly wacky ideas that turn out to be sensible and revolutionary. It's sharp end science at the very apex."

Fear
In the last few years there has been a revolution in the study of emotions. Fear, anger, love desire, give colouration and meaning to everything in life - and the derangement of emotions is what leads to the profound pain and much of the disability experienced in mental illness.
With the advance in brain imaging techniques, researchers are finally getting to grips with "seeing" our feelings - and in Frontiers, Peter Evans follows the quest to elucidate the most important of emotions, fear. It is vital for our survival in the face of danger but, when not regulated, it can become responsible for anxiety disorders and some of the symptoms of depression.
The emotion of fear relies on pathways that involve a structure deep in our brains called the amygdala. As the circuitry is being worked out, new clues are finally arising as to how we store information for fearful situations, how memory gets enhanced, how we subconsciously take in information about threat and fear - even though we might not be concentrating on it. New evidence also suggests that phobias may be hitchhiking on the same pathways used by normal fear.
As we come close to seeing the brain in the act of storing information about the signal that predicts danger, a new tool opens up in the attempt to study the effects of medication and psychological therapies on a variety of mental illnesses.
