岛盖(英文:Operculum),可分为额叶岛盖、颞叶岛盖或顶叶岛盖,共同覆盖大脑皮层中的岛叶[1][2][3]

结构

编辑

岛盖覆盖岛叶,后者是大脑皮层的一处内陷结构,埋藏在外侧沟深处[4]。其中,额顶叶岛盖(frontoparietal operculum)位于中央前回中央后回[1][5]

胎儿一般在母体怀孕第20-22周开始形成岛盖,其中在产前发育第14-16周时,大脑表面开始出现相关的内陷结构[6]

功能

编辑

额叶岛盖与思考、认知以及规划行为紧密相关[1][7]。颞叶岛盖包含颞横回,与听觉相关[1][8]。额顶叶岛盖与味觉品质、初级感觉以及运动功能相关[1][2][9]
