目的：研究脑岛区脑回和脑沟的形态。这项研究检查了20个被福尔马林固定的大脑半球（10个左右半球）。观察描述：岛沟周围、岛沟和脑回的解剖变化、岛中央沟和大脑中央沟之间的关系以及岛动脉的解剖结构。每个岛呈梯形，周围有四个岛周围沟（前、上、后、下）。我们区分了岛周后沟和岛周下沟。这两条沟有两个不同的轴，中间有一个明显的角。岛中央沟将岛分成两部分。前岛包括三个短脑回和前岛极。后岛包括两个长脑回和后岛极。这个结构定义了两个岛内包。在60%的病例中，岛中央沟的上端与大脑中央沟的下端直接连续。大脑中动脉的上支支配大部分的岛前回，下支支配大部分的岛后回。本研究详细描述了每个岛岛结构（脑回、脑沟和脑极）的形态，这些数据可以促进手术进入这一皮层深部区域，并有助于未来将解剖学与功能联系起来的工作。
To study the morphology of the gyri and sulci of the insular region.This study examined 20 formalin-fixed cerebral hemispheres (10 right and 10 left). Observations described: the peri-insular sulci, anatomical variations in the insular sulci and gyri, and the relationships between the central insular sulcus and the central cerebral sulcus and the anatomy of the insular arteries.Each insula had a trapezoid shape, surrounded by four peri-insular sulci (anterior, superior, posterior, and inferior). We differentiated the posterior peri-insular sulcus from the inferior peri-insular sulcus. These two sulci have two different axes separated by a clear angle. The central insular sulcus divides the insula into two parts. The anterior insula includes three short gyri and the anterior insular pole. The posterior insula includes two long gyri and the posterior insular pole. This structure defines two intra-insular opercula. In 60% of cases, the superior extremity of the central insular sulcus is in direct continuity with the inferior extremity of the cerebral central sulcus. The superior branch of the middle cerebral artery supplies the majority of the anterior insular gyri, and the inferior branch supplies the majority of the posterior insular gyri.This study details the morphology of each insular structure (gyri, sulci and poles), data which could facilitate surgical access to this deep cortical area and assist in future work correlating anatomy with function.
