Indians have smaller brains, reveals study
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.
Jayanthi said that even Chinese and Korean brain templates had been constructed, but there was no corresponding template for the India-specific population. She said that the first attempt by the IIIT-H team at creating an India-specific atlas involved 50 individuals, evenly balanced out across genders.
“MRI scans of these subjects’ brains were taken at three different hospitals across three different scanners to rule out variations in scanning machines. Emboldened by the results of the pilot study, we went on to recruit 100 willing participants in the eventual construction of the atlas, referred to as IBA 100,” she added.
Jayanthi said that the atlas was validated against other atlases for various populations. “These differences in height, width, and volume are found even at the structural level, such as in the volume of the hippocampus and so on. But overall, IBA 100 is more comparable with Chinese and Korean atlases than the distant Caucasian one (MNI),” she said.
She added that her team is currently focussing on understanding the aging process. “There are many changes that take place in a brain due to advancing age, with the most typical one being atrophy, shrinking of structures,” She also added that this will help in diagnosing dementia or Alzheimers as they are associated with atrophy of the hippocampus.

This whole news is about the frame size of the brain , not the function . If indians brain is not as smart as Europeans or American then why they have to depend on indian doctors and Engineers.

Where were the samples taken from? What kind of population are they talking about? Ethnicity of Indians varies across the country, esp. a broad north and south difference, and there are even differences between states from one region. Results cannot be generalized for all of India.

Haha as a doctor i would say it doesn''t matter. Smaller is not always worse. Latest processors are smaller and faster. It''s evolution. We are higher on evolutionary chain than others . Cro magnon was a primitive human and had brain of 1600 cc and was dumb , whereas sapiens have 1300 cc.

Agree totally . Indian brain are much evolved . This proved by the fact that most Indians are good in basic mathematics and problem solving skills compared to Western counterparts

I really don''t think the size of the brain matters. I think Einstein had a smaller than average brain. But most of on this forum won''t know that.

There is direct co relation between intelligence and body to brain ration. Also, Avg IQ of Indians is not great.

Brahmin brain is larger than 90% of Europeans this is why they are one of the most intelligent people on earth. This gives rise to immense jealousy from Dalits, Muslims, convert Christians and other low IQ groups.

The average IQ of india is 82, among the lowest in the world. You can Google it. There is no correlation between brain size and IQ though.
