Recently it has become possible to undertake what had previously been thought impossible - charting the activities of the mind, such as memory and thought. Join Dr. David Suzuki as he investigates evidence that our minds - thoughts, feelings, spirituality and creativity - are merely complicated networks of biochemical reactions. Imagine the dramatic social implications this theory could have on the world today. Memory: An aneurysm deep in the "reptilian brain" of former law student Jeremy Cuss left him amnesic - proving that the hippocampus is linked to short-term memory. How can this help doctors cure Alzheimer's, one of the most debilitating brain diseases known? The Miraculous Mind: Learn how the brain's ability to reconnect neural pathways after severe injury, such as a stroke, may be its most remarkable characteristic. The secret may be in a tiny bundle of 6,000 neurons in the brain stem - altogether, the size of a pea.
