Based on more than 8000 autopsies of male and female patients without brain diseases the normal brain weight of adult males and females in relation to sex, age, body-weight, and body-height as well as Body Mass Index were calculated. The average brain weight of the adult male was 1336 gr; for the adult female 1198 gr. With increasing age, brain weight decreases by 2.7 gr in males, and by 2.2 gr in females per year. Per centimeter body height brain weight increases independent of sex by an average of about 3.7 gr. Body Mass Index is of minor importance and only relevant in males. Based on these data the independent variables, age and height, were for the first time combined in a nomogram for the calculation of brain weight. The mathematical functions were integrated in a computer program which facilitates the calculation of normal brain weights in individual cases.
基于8000多例无脑部疾病的男性和女性患者的尸检，计算了成年男性和女性的正常脑重与性别、年龄、体重、身高以及体重指数的关系。成年男性的平均脑重为1336克；成年女性为1198克。随着年龄的增长，男性脑重每年减少2.7克，女性每年减少2.2克。每厘米身高的脑重增加，与性别无关，平均约为3.7克。体重指数的影响较小，仅在男性中相关。基于这些数据，首次将年龄和身高这两个自变量组合在一个列线图中用于计算脑重。数学函数被整合到一个计算机程序中，该程序便于计算个体病例的正常脑重。
