Research on Brain Mapping

Various experiments have been Conducted among the scientists to map the connections in the brain this is called as 'connectome’ and to understand how it relates to human behaviour, such as intelligence and mental disorders.

Research published in the journal Neuron, Scientists of the University of Cambridge and the National Institutes of Health (NIH), USA, has shown that it is possible to build up a map of the connectome by analysing regular brain scans taken by magnetic resonance imaging (MRI) scanner.

The group compared the brains of 296 typically adolescent volunteers. These results were certified in a cohort of a further 124 volunteers. The group used conventional 3T MRI scanner, i.e. where 3T represents the strength of magnetic field. Cambridge has recently install a much more powerful Siemens 7T Terra MRI scanner, which should allow the technique to give an even more precise mapping to the human brain.

MRI scan will be providing a one image of the brain from which, it is possible to calculate the multiple structural features of the brain. The scientists must show, that if two regions have similar profiles and have 'morphometric similarity'.

Morphometric similarity network, the scientists must generate a map showing the connection between every neuron to neuron. Scientists found a link among the connectivity channel.

"What makes some brains more connected than to others, as it is down to their genetics or their educational upbringing, i.e., how do these connections strengthen or weaken across development?"
