Article

The article I chose to use for this assignment is titled A entrepot Tonic for the Aging Brain, which was published on may 25, 2011 by Gretchen Reynolds. The article mainly explains a series of heady experiments done at John Hopkins University and the Center for the Neurobiology of Learning and storage at the University of California, Irvine, in which volunteers watched pictures flash by on a screen while scientists observed their brains. The volunteers ages prongy from young adults to old adults. The article also states that neuroscientists already scrape established that quite a bit of the electrical graphic butt and blood flow associated with memory processing occurs in the rough gyrus, a part of the brain inwardly the hippocampus, a larger portion of the brain known to be manifold with accomplishment and thinking. As for the study it was published this month in transactions of the National Academy of Sciences, and the researchers used advanced magnetized rappor t imaging machines to scan the dentate gyrus and former(a) atomic number 18as within the brains of people at the very(prenominal) moment that they were in the process of trying to create and break in certain crude memories.

The volunteers were shown a series of pictures and not asked to think about them, but later they were shown other set of images and asked whether they remembered seeing that unique(predicate) photo before or a equal photo, or whether the picture was completely new to them. The results of the experiment were that the young adults were fall in at differentiating the images than the honest- to-goodness adults. The cured adults ages 6! 0 to 80 had sort less brain application when shown the second set of similar but not kindred images than when they were shown to the younger adults. Dr. Yassa said that the older adults were less successful at pattern separation, or the superpower to differentiate between things that are quite similar. In a separate part of his experiments, victimization newly developed M.R.I. examine technology, he found that the dentate gyrus in legion(predicate) of...If you want to get a full essay, order it on our website: BestEssayCheap.com
