For a long time , astrocytes have been thought to provide mainly a structural , trophic , and metabolic support to neurons . with the development of research techniques , a growing body of evidence has emerged on the existence in the brain of a close bidirectional communication between neurons and astrocytes . astrocytes are not inertia cell and can regulated actively neuronal activity 傳統觀點認為,星形膠質細胞( ast )對神經元起支持、營養和保護功能,但隨著研究技術的不斷進步,越來越多的證據表明, ast并非惰性細胞,而是與周圍神經元之間存在雙向通訊,并能主動調控神經元的活動。 |
