科技日报电,日本理化研究所脑科学综合研究中心平濑肇和大江祐树等领导的联合研究小组,开发出一种脑内糖原分布变化可视化技术,并利用这一技术成功观察到脑内糖原随年龄改变的分布变化。糖原是由肝脏和肌肉合成并储存能量的一种多糖,在脑中也有储存。科学家最近发现,糖原不仅是脑活动的能源,还参与记忆固定等重要的大脑活动。但脑糖原极微量且易于分解,以目前的方法不可能保存脑糖原并使其可视化,因此无法在细 Science and Technology Daily News, Japan Institute of Physical and Chemical Research Center for Brain Science Ping Ping and Ozawa Yushu, and other leaders of the joint research team to develop a visual brain distribution of changes in glycogen technology and the use of this technology successfully observed in the brain Glycogen changes with age distribution changes. Glycogen, a polysaccharide that is synthesized and stored by the liver and muscle, is also stored in the brain. Scientists recently discovered that glycogen is not only an energy source of brain activity but also involved in important brain activities such as memory fixation. However, since the original amount of brain glycogen is very small and easily decomposed, it is impossible to preserve and visualize brain glycogen in the current method
