Todd Suomela on 25 Jan 09In 1953, he underwent an experimental brain operation in Hartford to correct a seizure disorder, only to emerge from it fundamentally and irreparably changed. He developed a syndrome neurologists call profound amnesia. He had lost the ability to form new memories. For the next 55 years, each time he met a friend, each time he ate a meal, each time he walked in the woods, it was as if for the first time. And for those five decades, he was recognized as the most important patient in the history of brain science.
