研究目的

本组基于控制学习行为的神经基础形态差异,为了从比较解剖学角度验证古人和新人的学习能力差异,开发出可对收纳大脑的容器即头骨化石及其大脑模型进行精确复原的方法,目的是对头骨中原有的大脑(大脑化石)进行假设复原。具体来说,一般所发现的头骨化石为碎片状,开发出可对这些碎片头骨化石进行组合和形变校正的新型精确复原方法,制作古人和新人头骨化石及大脑模型的正确3D模型。向C02组提供该复原头骨模型的同时,与其进行共同合作,对原本存在于其中的大脑化石进行复原和详细的形态学分析,考察头骨和大脑形态的进化过程。


研究方法:

(1)根据头骨化石的CT积层断层图像,在假设空间内构筑头骨化石的3D数码模型,引用工程学方法进行化石组合和去除变形,再次精确构筑其立体形状。

(2)对现代人类的头骨模型进行假设性分割和变形,通过在各种条件下对其进行逆变换(即复原),对方法的适当性和界限进行评估。

(3)将以上所形成的数据提供给C02组的同时,根据C02组所形成的学习能力相关大脑功能分布图的反馈信息,对头骨和大脑形态进行客观定量解析。

(4)采用多个古人头骨化石尝试上述作业,进行标准化,对古人大脑化石的形态特征进行假定复原。
