ScienceDaily (Apr. 1, 2008) — Biologists have just confirmed what poets have known for centuries: eyes really are windows of the soul--or at least of the brain.

Current methods involve a risky, invasive, and relatively slow process of penetrating the skull to extract tissue samples and then examining those samples in a laboratory.
