Indians have smaller brains, reveals study
Chinese, Caucasians Have Bigger Brains: IIIT-H
Hyderabad: Researchers at the International Institute of Information Technology, Hyderabad (IIIT-H) have created the first-ever Indian Brain Atlas. The study has revealed that the Indian brain, on an average, is smaller in height, width and volume when compared to Western and other eastern populations. This will help in early diagnosis of Alzheimer’s and other brain-related ailments.
The research has been published in Neurology India, a peer-reviewed journal.
Jayanthi Sivaswamy of the Centre for Visual Information Technology, who worked on the project, said that the Montreal Neurological Institute (MNI) template, which is used as the standard, was created using Caucasian brains. This, according to the researchers, is not ideal to analyse brain differences in the Indian population.
“As Indian brains are smaller in size when compared to MNI, the difference in scans can look alarming and lead to misdiagnosis,” Jayanthi told TOI. She added that MRI images are compared with pre-loaded MNI template to arrive at a diag
