Schnell mal einen Link zu National Geographic, das einen schönen Artikel hat zum Gehirn, Gedächtnisleistung und seltsamen Streichen, die uns der Klumpen spielen kann. Ich konnte mich kaum für einen Teasertext entscheiden, daher copypaste ich mal den Anfang zum Anfixen:

„There is a 41-year-old woman, an administrative assistant from California known in the medical literature only as “AJ,” who remembers almost every day of her life since age 11. There is an 85-year-old man, a retired lab technician called “EP,” who remembers only his most recent thought. She might have the best memory in the world. He could very well have the worst.

“My memory flows like a movie””nonstop and uncontrollable,” says AJ. She remembers that at 12:34 p.m. on Sunday, August 3, 1986, a young man she had a crush on called her on the telephone. She remembers what happened on Murphy Brown on December 12, 1988. And she remembers that on March 28, 1992, she had lunch with her father at the Beverly Hills Hotel. She remembers world events and trips to the grocery store, the weather and her emotions. Virtually every day is there. She’s not easily stumped. (…)

EP’s hippocampus was destroyed, and without it he is like a camcorder without a working tape head. He sees, but he doesn’t record.
EP has two types of amnesia””anterograde, which means he can’t form new memories, and retrograde, which means he can’t remember old memories either, at least not since 1960. His childhood, his service in the merchant marine, World War II””all that is perfectly vivid. But as far as he knows, gas costs less than a dollar a gallon, and the moon landing never happened.“
