Listen: What Craniopagus Twins Say about Mind and Brain

On a new episode of ID the Future, neurosurgery professor Michael Egnor explores the case of Tatiana and Krista Hogan, the “Craniopagus Twins.”

Their condition, he says, provides evidence against strict materialism.  Tatiana and Krista are connected at the thalamus (which controls such things as wakefulness, motor function, and vision) through a structure called a thalamic bridge. This bridge enables them to see through each other’s eyes and control each other’s limbs. Egnor explains how their separate personalities and thoughts nevertheless show that there is something about the mind not reducible to the brain.

He also describes the mind-brain research of Roger Sperry, Benjamin Libet, and Wilder Penfield.  Listen to the podcast here.
