Science writer Charles Fernyhough, author of the new book, Pieces of Light: The New Science of Memory, offered this explanation in The Guardian:
Personal memories are more like mental reconstructions where the original details are contorted, at least to some degree, by who we are today. The challenge, we think, is in retrieving the uncorrupted files.īut recent research suggests that memory doesn’t work like that.
We like to believe that memories, once created, are like data filed away, constant and enduring. What about the rest of us? Our personal memories are much more erratic, some powerfully vivid, most frustratingly murky. Is it all about how brain structures communicate? Is it genetic? Is it molecular? To follow the clues, they’re analyzing at least another three dozen people who also seem to have the uncanny ability to retrieve their pasts in precisely-drawn scenes. But they’re anxious to see where this leads and what it might teach them about how memory works. They don’t know how much, or even if that behavior is directly related to a person’s autobiographical memory. The scientists are wary, as yet, of drawing any conclusions. Many were collectors–of magazines, shoes, videos, stamps, postcards–the type of collectors who keep intricately detailed catalogs of their prized possessions. In line with that discovery, the researchers determined that the study’s subjects were more likely than usual to have OCD tendencies. Also, the region of the brain often associated with Obsessive-Compulsive Disorder (OCD), was larger than normal. They had stronger “white matter” connections between their mid and forebrains, when compared with the control subjects. They found, not surprisingly, that their brains are different. How does science explain it? Well, the research is still a bit limited, but recently scientists at the University of California at Irvine, published a report on 11 people with superior autobiographical memory. Nope, only in the recollection of the days of their lives are they exceptional. In fact, they generally perform no better on standard memory tests than the rest of us. These are not savants who can rattle off long strings of numbers, Rainman-style, or effortlessly retrieve tidbits from a deep vault of historical facts. What makes this condition, known as hyperthymesia, so fascinating is that it’s so selective. The most famous is probably actress Marilu Henner, who showed off her stunning recall of autobiographical minutiae on “60 Minutes” a few years ago. Others, no doubt, have this remarkable ability, but so far only those 33 have been confirmed by scientific research. Pick any date and they can pull from their memory the most prosaic details of that thin slice of their personal history. Or who they talked to on October 28, 1986.

HYPERTHYMESIA VS EIDETIC HOW TO
Okay, I'm not sure how to change it or make it into a link.Memory is a collaborative effort within the brain. Hyperthymesia is the proper condition to describe Thane's unique alien brain architecture.- Captainhu 02:15, Aug(UTC) I know it's nitpicking, and I'm not trying to be a jerk or anything, I just thought it would be cool to have it a little close to correct. I'm sure it could be eidetic, but eidetic is flawed in that the memory does fade eventually, whereas Thane's memories from years ago are perfect. So in addition to remembering everything he's been through, he feels them as well. I know he says Drell have perfect memories, but it seems more like an advanced form of hyperthymesia. From the way Thane describes it, it seems like he has hyperthymesia, meaning that he perfectly recalls everything he experienced.
Hyperthymesia is absolute perfect recall of all personally experienced events. Eidetic memory is the ability to recall almost every detail about something studied. I'm curious as to which condition applies more accurately for Thane (or any Drell). Forums: Index > Help desk > Eidetic Memory or Hyperthymesia?
