概括

用3D成像分析了单胞胎双胞胎的软组织差异. 脸部和下巴的下部表现出最多的变化,这表明了不同的遗传和环境影响.

科学领域:

ортодонтика和面研究.

背景情况:

单胞胎 (MZ) 双胞胎共享相同的基因,使他们对研究面部发育的遗传与环境影响有价值.
评估微妙的软组织变异对于理解面部生长模式至关重要.

研究的目的:

量化单胞双胞胎的全脸和特定面部区域的软组织差异.
利用先进的3D立体相像测量和基于表面的偏差分析进行精确的测量.

主要方法:

14个未经治疗的单胞胎双胞胎对使用3dMDface系统进行了3D面部成像.
在图像叠加后,使用立体石版 (.stl) 文件进行了基于表面的3D偏差分析.
脸部被划分为三分之一,以及上唇和下唇/下巴区域,以便进行详细的比较.

主要成果:

在面部三分之一之间没有发现平均软组织偏差的显著差异.
根平均平方 (RMS) 值显示了上面和下面以及唇部/下巴部之间的统计学上显著差异.
中位数和四分位数间范围分析显示,面部区域之间没有显著差异.

结论:

下面的面部三分之一和下唇/下巴区域在单胞胎双胞胎中表现出最显著的软组织变异.
这些发现表明,遗传和环境因素可能对各种面部区域产生不同的影响.

关键词:

分析3D偏差的分析.这是一种单胞性单胞性.这是一种立体摄影仪表学.他们是双胞胎,双胞胎.

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
