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?"
