Spicy ginger or too old to unveil the elderly brain science better than poor young man!

 Introduction: People often hear the old complaint: not only did not diminish the brain, and in some ways far better than young people. then we can understand the on the decline in their function, two recent studies have inventive, trying to better reveal the little-known aspect of the aging brain. University of Michigan, Ann Arbor (University of Michigan, Ann Arbor) about the challenge of the task of brain areas related to report, Johns Hopkins University (Johns Hopkins University) for the Experimental Analysis of older mice mm Both studies found that aging of the brain and the young brain there are differences in the mode of operation.
University of Michigan, Ann Arbor Branch of Cindy. Lustig (Cindy Lustig) using functional magnetic resonance imaging to observe the young group (18 to 30 years) and elderly (65 to 92 years) volunteers respond to different brain when the difficulty of intelligence tests information. When the deal with relatively simple problems, the young group and elderly group of subjects the brain works almost the same; However, when dealing with difficult issues,bailey UGG boots, the difference would have emerged. elderly activated at the front of a few brain areas, but young people do not. Another difference is that young people in problem-solving process will be In the activated state. Lustig concluded,UGG shoes, Hopkins University, Mi Kaila. Gallagher (Michela Gallagher) on the six months of a large rat pups and two years old (higher than the average life span of mice) were compared with observation. her older experimental group further mice were divided into functional groups and functional decline is still a sound group. Gallagher compared the distribution of their synapses mm gap in the small neurons, the connections of neurons and is responsible for the organization of information transfer between cells and found that functional decline group of mice group showed a loss of synapses will adjust the capacity of activity, while still robust set of functional groups of rats did not. It is in these connections and they produce and store the memory keys.
