封面和图1。（封面）矢状面、冠状面和轴位MRI扫描显示了脑梗死的大致位置和范围。中央沟将小脑分为前叶（粉红色）和后叶（绿色）。（左）在轴向MRI上显示了在鳃盖和屏状骨之间的骨的位置。（中）一张简化的矢状面图描绘了脑回。（右）识别一个区域内可能的功能细分的一种方法是创建细胞结构（细胞结构）的地图。最近的一项人体研究报告了细胞结构从背后颗粒区（G和g）到腹前无颗粒区（a2-a1）的进展，并伴有异常颗粒皮质的过渡区（d3-d1）。的位置和范围的七个cytoarchitectonic细分确定的近似简化矢状图。图1显示了包含大部分von Economo神经元（VEN）的位置（由白色线包围的区域）。
Cover and FIGURE 1.(Cover) The approximate location and extent of the insula is illustrated on sagittal, coronal, and axial MRI scans. The insula is divided by the central sulcus into anterior (pink) and posterior (green) lobes.(Left) The insula’s location between the opercula and the claustrum is illustrated on an axial MRI.(Center) A simplified sagittal drawing of the insula depicts the major gyri.(Right) One way to identify possible functional subdivisions within an area is to create maps of the cellular structure (cytoarchitecture). A recent study in humans reported a progression in cellular structure from the dorsal-posterior granular region (G and g) to the ventral-anterior agranular region (a2–a1) with a transition zone of dysgranular cortex (d3–d1). The locations and extents of the seven cytoarchitectonic subdivisions identified are approximated on a simplified sagittal drawing. 1 The locations containing the majority of von Economo neurons (VENs) are indicated (region enclosed by white line).
