Sound During Sleep Fixes Learning: Scientific American Podcast
There’s nothing like a good nap. It can refresh your mood—and possibly your memory. Because a new study in the journal Science shows that a quick snooze after a mental workout helps to consolidate learning. And that sounds heard during sleep can trigger associations that sharpen memory even more.
Neuroscience: Small, furry … and smart
Tsien, based at Princeton University in New Jersey at the time, named his creation Doogie after the teenage genius in the television programme Doogie Howser, MD. The work was one of the earliest examples of neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.

Much of the work involves making an adult brain behave more like a younger, more flexible version of itself by increasing the organ's plasticity.

Vision, the Brain and Memory: The ups and downs of forgetting (Samuel Wang)
Total Recall: The Woman Who Can't Forget
I first saw Price last May in a YouTube clip of her on 20/20. Diane Sawyer asks Price, an avid television viewer, to identify certain significant dates in broadcast history. When did CBS air the "Who shot JR?" episode of Dallas? When was All in the Family's baby episode shown? And so on. Price nails every question. She not only gives the date for the final episode of MASH but describes the weather that day.
Freedom of Memory Today by Adam Kolber
Emerging technologies raise the possibility that we may be able to treat trauma victims by pharmaceutically dampening factual or emotional aspects of their memories. Such technologies raise a panoply of legal and ethical issues. While many of these issues remain off in the distance, some have already arisen.
In this brief commentary for the journal Neuroethics, I discuss a real-life case of memory erasure. The case reveals why the contours of our freedom of memory -- our limited bundle of rights to control our memories and be free of outside control -- already merit some attention.
Reconstructive memory: Confabulating the past, simulating the future
The term 'Rashomon effect' is often used by psychologists in situations where observers give different accounts of the same event,and describes the effect of subjective perceptions on recollection. The phenomenon is named after a 1950 film by the great Japanese director Akira Kurosawa.
Brain Researchers Open Door to Editing Memory
Researchers in Brooklyn have recently accomplished comparable feats, with a single dose of an experimental drug delivered to areas of the brain critical for holding specific types of memory, like emotional associations, spatial knowledge or motor skills.
Using False Photographs to Create False Childhood Memories
Because image-enhancing technology is readily availabl e, people are frequently exposed to doctored images. However, i n prior research on how adults can be led to report false childhood memories, subjects have typical ly been exposed to personal ized and detailed narratives describing false events. Instead, we exposed 20 subjects to a false childhood event via a fake photograph and imagery instructions.
Memory Switch Could Enable Brain Hacks
Forget the memory-boosting pills: In the future, powers of recall could be boosted with programs on a handheld PDA.
A Hormone to Remember
Given only a small dose of oxytocin, individuals in a recent study found that their memory significantly improved. Not for historical dates, strings of digits, or bars of music, but for something much more significant: each other. (Seed)
Eyewitness: How Accurate Is Visual Memory?
How difficult is it to manufacture someone else`s memory? Psychology professor Elizabeth Loftus says it`s a whole lot easier than you might think.
A mother's experience can alter her offspring's memory performance.
If a similar phenomenon occurs in humans, the effectiveness of one's memory during adolescence, particularly in those with defective cell signaling mechanisms that control memory, can be influenced by environmental stimulation experienced by one's mother during her youth. (Deric Bownds' MindBlog)

The Simpsons Excites and Re-excites the same Neurons
"In the study, Prof. Fried observed the neural activity in the brains of 13 epilepsy patients, as the patients watched clips from TV shows like Seinfeld and The Simpsons. A short while after, the test subjects were asked to describe what they remembered from the video clips. During recall, the exact same neurons that had fired while viewing a clip fired once again while the subject was recalling it. Soon, the researchers were able to predict what clip the subjects would recall just by looking at the neurons that lit up seconds before the recall experience was vocalized."
Scientists may soon be able to erase fear and trauma from your mind
Neurobiologists believe they will soon be able to target and then chemically remove painful memories and phobias from the mind without causing any harm to the brain. (Telegraph)
Jacking into the Brain--Is the Brain the Ultimate Computer Interface?
How far can science advance brain-machine interface technology? Will we one day pipe the latest blog entry or NASCAR highlights directly into the human brain as if the organ were an outsize flash drive? (Scientific American)
How Lies Live and Grow in the Brain
"The brain does not simply gather and stockpile information as a computer’s hard drive does. Facts are stored first in the hippocampus, a structure deep in the brain about the size and shape of a fat man’s curled pinkie finger. But the information does not rest there. Every time we recall it, our brain writes it down again, and during this re-storage, it is also reprocessed. In time, the fact is gradually transferred to the cerebral cortex and is separated from the context in which it was originally learned. For example, you know that the capital of California is Sacramento, but you probably don’t remember how you learned it." ( NYTimes.com)
Anatomy of a false memory
"If confabulation occurs following damage to the ventromedial cortex, what functions might this part of the brain be involved in? Some researchers have suggested that it normally suppresses memories that are not relevant to the current situation, while others argue that it acts as a monitoring system which normally rejects false memories that don't "feel right"."
