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
