false memory
Do you ever doubt your own memory? New research at the Institute suggests that some of the things we think we remember could be wrong. It seems that our brains are surprisingly willing to exchange a true memory for a false one, just on the basis of friends' claims. The scientists not only demonstrated just how easy it is to create false memories, they showed that the switch in memory has a signature pattern of brain activity. The most significant feature? They found strong connectivity between areas of the brain known to be involved in memory and learning, and the amygdala, which, among other…
THE humble fruit fly (Drosophila melanogaster) has the ability to learn and remember, and to make predictions about the outcome of its behaviours on the basis of past experience. Compared to a human brain, that of the fruit fly is relatively simple, containing approximately 250,000 cells. Even so, little is known about the anatomical basis of memory formation. The neural circuitry underlying memories in these insects has now been dissected. In an elegant new study published in the journal Cell, researchers from the University of Oxford show that aversive memories are dependent on a tiny…
