Volatility of Human Memory
prostoalex writes "Scientific Americans looks into the human brain, trying to figure out why some events just tend to stick in our memories forever, while the others are gone: "How does a gene "know" when to strengthen a synapse permanently and when to let a fleeting moment fade unrecorded? And how do the proteins encoded by the gene "know" which of thousands of synapses to strengthen? The same questions have implications for understanding fetal brain development, a time when the brain is deciding which synaptic connections to keep and which to discard. In studying that phenomenon, my lab came up with an intriguing solution to one of these mysteries of memory.""
If we can figure out what proteins need to be expressed to convert short term to long term memory and somehow in the future find some sort of drug that ups the expression of that gene we will still have a problem with what do you do when every memory is a lasting one? Do ou need to know the plate# of every car you drove by on the way home or the order of the commercials when watching Oprah? I think if we mess with the number of long term memories we make we may also lose the selectivity which is so important in making sure the brain isn't cluttered with irrelevant memories and we strengthen only important ones.
Increase the signal to noise ratio of my memory, then w're in business.
