Examining population differences in cerebral morphometry between Chinese and Indian undergraduate students

Area of Science:

• Neuroscience
• Anthropology
• Medical Imaging

Background:

• Understanding population-specific variations in brain structure is crucial for neuroscience and anthropology.
• Magnetic Resonance Imaging (MRI) provides detailed insights into brain morphometry.

Purpose of the Study:

• To investigate ethnic differences in brain morphometry between Chinese and Indian undergraduate students.
• To analyze variations in gray matter volume, cortical thickness, and cortical surface area.

Main Methods:

• Utilized MRI scans from 36 Chinese and 32 Indian undergraduate students.
• Employed the BrainLab toolbox for processing and obtaining morphometric values.
• Conducted region of interest (ROI)-based analysis to compare brain structures.

Main Results:

• Significant population-related differences in brain morphometry were observed between the Chinese and Indian groups.
• Cerebral variations were predominantly found in the frontal, temporal, and occipital lobes.
• Subgroup analysis indicated sex-based differences within the studied populations.

Conclusions:

• Brain morphometry, including gray matter volume, cortical thickness, and surface area, exhibits population-specific variations.
• Ethnic background is a significant factor influencing brain structure in young adults.
• Further research is warranted to explore the implications of these findings.
