There is evidence that new memories can partially override old ones, so seeing a white house similar to Grandma’s yellow one might unconsciously tint the original memory. Lynch says it is not known exactly how this happens. As soon as the need for the information is gone, scratch-pad memory tosses it overboard.īut how could the memory of Grandma’s white house be so vivid yet so wrong? This also explains why you don’t remember the time only seconds after looking at your watch. The hormones released when you feel strong emotions intensifies these memories, and your hormones really pumped on prom night.īut the location of your keys was recorded in your “scratch-pad memory,” which is separate and notable for two qualities: You can’t store much information there, and the information evaporates quickly, usually within a few hours. The prom is engraved in your “episodic memory,” a very powerful system for preserving the rich details of events. You are using two physically separate kinds of memory, Lynch says. Why is it you can remember the prom but not where you put your keys? What we know now compared to just five years ago is incredible.” A decade of discoveries now allows science to describe “with some degree of confidence things that would have sounded like science fiction 10 years ago. So far, its effect in people is untested.īut this is only the latest development in brain research, Lynch says. The university has licensed an Irvine pharmaceuticals firm to develop Ampakine as a possible prescription drug, hoping it will increase memory in mild cases of dementia, stroke and Alzheimer’s disease.
