(Via Gainsville.com). Why does the aging brain lose memory abilities? "The traditional thinking is that when older people lose the ability to 'bank' new memories, it may be because of deterioration in the brain's temporal lobe. Loring believes it is possible that some older people actually lack the attention span to log new information into their memory, which places the problem in the prefrontal cortex - the brain's attention center - rather than the temporal lobe. ... We have all the tools in our hands; the problem is combining the right people with the right cells to answer the question of what kind of genes contribute to long-term memory formation. Nobody really understands on the level of specific cells how many genes work together. We are excited because this is the first time we will be able to monitor all the genes in specific neurons."
