研究人员记录了53具人类尸体的中枢大脑温度，这些尸体被储存在10摄氏度到30摄氏度的恒定环境温度下。测量平均在死后1.6小时开始，并持续8-50小时。温度曲线的S形形状符合马歇尔和霍尔（1962）的数学模型。该模型提供了温度曲线的精确描述。对于44具尸体，在10摄氏度到25摄氏度之间的温度下进行研究，使用模型适应参数的固定值计算死亡时间。95%容许限度的误差范围为+/- 1.5 h至尸检后6.5 h，+/- 2.5 h至尸检后10.5 h，+/- 3.5 h至尸检后10.5 h。对于推荐的实际应用，提出了“脑温-死亡时间”列线图。我们发现冷却的速度受到头发数量的影响。此外，有人认为，研究方法可以进一步改进。因此，我们预计，在计算死亡时间时，中枢脑温度甚至比根据现有材料所讨论和显示的更准确。
The central brain temperature was recorded in 53 human corpses, stored at constant ambient temperatures between 10 degrees and 30 degrees C. The measurements were started on average 1.6 h post mortem and continued for 8-50 h. The sigmoidal shape of the temperature curves fitted the mathematical model of Marshall and Hoare (1962). This model provides a precise description of the temperature curves. For 44 corpses, studied at temperatures between 10 degrees and 25 degrees C, the time of death was calculated using fixed values for the adaptation parameters of the model. The margins of error for the 95% tolerance limit were +/- 1.5 h up to 6.5 h post mortem, +/- 2.5 h between 6.5 and 10.5 h post mortem and +/- 3.5 h between 10.5 and 13.5 h post mortem. For the recommended practical application a "brain temperature--time of death" nomogram is presented. We found that the rate of cooling was influenced by the amount of hair. Furthermore, it has been argued that the study method could be improved further. In consequence, we expect the central brain temperature to be even more accurate in the calculation of the time of death than has been discussed and shown on the basis of the present material.
