Indians have smaller brains, reveals study

[PradoTLC]

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 diagnosis. “There is clear evidence based on the study that it is desirable to build a larger atlas as it is important to understand structurally what is normal. This would help catch several brain conditions early on.”


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.

a nation that thinks it is cool to drink cow piss or call their god a pile of stone....

so surprise surprise?...

What a circle jerk thread, holy shit.

 

[Indus Pakistan]

A considerable chunk of North India has the same light blue patch...and Bulk of Indian population is in the north.If Pakistan was 5-10 points ahead of India in terms of IQ, Believe you me, Pakistan would be of the same standard today as Turkey,Brazil,Argentina,Malaysia

The fact is there is a differance. You can't expect huge differances between neighbours but that differance is there and is even more pronounced with South India which is scoring with Africa, not entirely surprised about that.

Bulk of Indian population is in the north.

If you look at the map I would say it is about about 55% that is falling in the light patch which still leaves 45% of 1.4 billion equal to about 650 million indians in Africa/par African category.

I may have many misgivings about how 1947 came about and how it was handled but still thanks god for 1947 which killed the British project in South Asia and placed the Durand Line. Phew ..... !

Dood different races have different brain volumes..Eskimos have the highest..Whites are at no 2 or no 3 spot..Indians will be low because

I wonder what may the reasons behind Eskimos having the largest brain size. Can it be lacking other foods they have the habits of too much eating of sea fish?

 

[loanranger]

I knew it all along. Brain size is directly proportional to intelligence.

They experienced the coldest weather for tens of thousands of years...which gave them the biggest brain volume...But their population density was low, which means the gene mutations that favoured even further intelligence spikes never really came about or could not spread among them...But yes the more animal protein you consume, the more brain mass and muscle mass you will carry on average..


Brain---------------------------------------------->Engine
Intelligence------------------------------------->Engine Power
IQ measurement------------------------------>Engine power measurement in terms of Horsepower through dynamometer
Brain Size--------------------------------------->Engine Displacement
Genetical Mutations for Intelligence--->High RPMs in smaller engines which makes it more powerful than larger Engines

So Ashkenazi Jews even though have smaller brains, they have high intelligence because somehow those favourable mutations for intelligence took hold in their populace the last 1300 or so years.(extremely small mutations over a few dozen generations can produce a 10 point gap in a 1,000 years)

Ashkenazi Jews may be likened to high performance Honda Engines that rev like F1 race cars and even though they are small 2 litre engines, they can give bigger 3-4 litre engines a run for their money

"Human intelligence is the intellectual prowess of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.[1] Through their intelligence, humans possess the cognitive abilities to learn, form concepts, understand, apply logic, and reason, including the capacities to recognize patterns, comprehend ideas, plan, solve problems, make decisions, retain information, and use language to communicate".

Above is what wiki says about human intelligence. Now, the cognitive abilities of the Eskimoes whose lifestyle, thought matters etc in the specialized geography of the North Pole are not supposed to increase their intelligence capacity although their brain sizes are larger comparing to others.

So, I fail to comprehend any direct relationship between brain size and intelligence.

 

[Indus Pakistan]

One thing for sure, we can all fight about who has higher IQ as it is very diificult to measure but i think nobody can argue that differant human groups have differant attributes clustered around them. Blacks for instance are faster, stronger, taller, darker then other demographic groups. Would it then not also follow other human traits [pos or neg] differ amongst differant demographic groups?

the tea is fantastic = high iq = cost of mig

 

[Nilgiri]

Dood different races have different brain volumes..Eskimos have the highest..Whites are at no 2 or no 3 spot..Indians will be low because

1) Indians are short..
reasons being

2) rampant vegetarianism,

3) tropical diseases(if you ever came down with a viral fever before adolescence,Boom there goes a fraction of a point of your intelligence),

4) parasitic load,

5) high allostatic load,

6) lack of iodized salt..

7) lack of hygiene

..But I am sure Pakistanis are within touching distance of India..Given Pakistanis are only 2 points and not even one inch taller than Indians on average

Here you go...Plenty of Indians and Pakistanis have same average brain size

1) IQ and brain size have very poor correlation.

2) IQ relevance to broader question of "intelligence" (esp functional) is ongoing debate, its not settled at all

3) You (and others) seem to have no understanding of where the "IQ Nations" clickbait stuff got its numbers from or what a terrible (low pop + heavy biased) sample it did and extrapolated. When you keep extenuating variables more controlled (i.e more unbiased) and actually DIRECTLY SAMPLE enough scale/volume recent and meaningful sample units. You get results like this one:

http://www.unz.com/jthompson/intelligence-of-5-year-olds-in-uk/

The socio-economic performance of these groups (say in the UK) can then also be correlated and start to be explained.

Indians average IQ is 82, which is borderline retarded

Probably explains Indian behaviour on PDF.

 

[Hakikat ve Hikmet]

PAF vs IAF “dog fights” have already proved it decisively?!! Anyway, a “scientific” corroboration always helps to justify the “observations”.....

yeah 1 abhinadan = 93k pakis

Still that tamil super hero got beaten by a few unarmed villagers

not poor but moderate correlation of 0.3 and 0.4 between intelligence and brain size...that is substantially significant in the social sciences/psychology where multiple competing causes are the norm

Now the immigrant groups to Western countries are irrelavant because they are a self selected cognitive elite. A huge percentage of Indian cognitive elite emigrates abroad permanently. So your studies ahould be taken with a pinch of salt. Studuies that take into account the bottom 80 percent of Indian population are much more relevant...You quote Anatoly Karlin and the scientist James Thompson. One look through their database, and you will find they overwhelmingly support the fact that there is moderate positive correlation between brain size and intelligence...I already explained small brains working at higher RPMs can have more intelligence than bigger brains running cooler..Jews are the prime example.But for that they pay the price with neurological disorders like Tay Sachs...Just like a high reving engine wears out faster than a large lazily revving engine
