目的探讨人大脑半球脑回形态观察的新途径,了解脑回形态的二元一次函数表述。方法以人大脑半球枕叶脑回为观察对象,利用脑后面特殊标志作坐标并测量,得出同一部位脑回二元一次函数,进行分析并归纳特征。结果得到枕叶降回形态变化的函数斜率和tan值,从而表示出脑沟的走向和曲折程度。结论二元一次函数能描述人脑脑回的形态特征,可以作为脑回形态表述的方法之一。
Objective To explore a new way to observe the morphology of cerebral hemispheric brain gyrus in human and understand the expression of bivariate one-time function of the morphology of brain gyrus. Methods Taking the occipital lobe of the human brain hemisphere as the observation object, using the special signs behind the brain as the coordinates and measuring, we got the bivariate linear function of the brain in the same part and analyzed and summarized the features. The results obtained by the occipital lobe morphological changes in the slope and tan value of the function, which shows the sulcus direction and tortuosity. Conclusions The bivariate function can describe the morphological characteristics of the brain and brain, which can be used as one of the methods to describe the morphology of the brain.
