Thibodaux native's son was world's most famous amnesiac

From CNN: Henry Molaison, known as H.M. in scientific literature, was perhaps the most famous patient in all of brain science in the 20th century.

"My daddy's family came from the South and moved North, they came from Thibodaux Louisiana, and moved north," Molaison would say. "My mother's family came from the North and moved South." Within 15 minutes he might repeat this exact statement twice more, unable to remember that he'd already said it. Scientists studied him for most of his adult life.

This week, researchers are dissecting his brain to figure out exactly which structures contributed to his amnesia, which he suffered for more than 50 years.
