High-Resolution Imaging Of Brain Offers Clues Related To Memory Loss In Older Adults
As we grow older, it is not rare to feel “senior moments,” in which we call our kids by the incorrect names or forget where we parked our car. And we might speculate: Are these lapses in memory a standard part of growing old, or do they indicate the early phases of a grave disease such as Alzheimer’s? Presently, there is no good method to tell.
Researchers from University of California in Irvine, on the other hand, have discovered that brain’s high-resolution fMRI (functional magnetic resonance imaging) can be employed to display some of the fundamental causes of distinctions in ability of memory between younger and older adults.
The research, which is posted this week in the journal Neuron, comprised 20 young adults (in the range of 18–31 Years old) and 20 cognitively fit older adults (in the range of 64–89 Years old). The members were asked to conduct 2 types of tasks while going through fMRI scanning—a location memory task and an object memory task. Because fMRI sees at the dynamics of flow of the blood to the brain, researchers were capable of determining which regions of the brain the members were employing for every activity.
In the 1st task, members looked at pictures of daily objects and were then asked to differentiate them from latest images. “Most of the images were the same to ones they had seen before while some were new. And others were same to ones they had looked at previously be we might have altered the size and the color,” claimed the senior author of the study and director for the Neurobiology of Learning & Memory of UCI’s Center, Michael Yassa, to the media in an interview. “We name these complicated objects as the ‘lures.’ And we discovered that older adults grapple while dealing with them. They are much more prone than younger adults to think they have looked at those lures before.”
