People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

First map of core white-matter connections of human brain developed at USC

RATE THIS! +32

USC neuroscientists have systematically created the first map of the core white-matter “scaffold” (connections) of the human brain, the critical communications network that supports brain function. Their work has major implications for understanding brain injury and disease.

 

By detailing the connections that have the greatest influence over all other connections, the researchers offer a landmark first map of core white matter pathways and also show which connections may be most vulnerable to damage.
 
“We coined the term white matter ‘scaffold’ because this network defines the information architecture which supports brain function,” said senior author John Darrell Van Horn of the USC Institute for Neuroimaging and Informatics and the Laboratory of Neuro Imaging.
 
“While all connections in the brain have their importance, there are particular links which are the major players,” Van Horn said.
 
Using MRI data from a large sample of 110 individuals, lead author Andrei Irimia, also of the USC Institute for Neuroimaging and Informatics, and Van Horn systematically simulated the effects of damaging each white matter pathway.

What a big differences MRI scans make for neuroscience and understanding of brain function! This is another example and the map of connections will definitely help

Already MRI can be considered the preferred neuroimaging examination for Alzheimer disease because it allows for accurate measurement of the 3D volume of brain structures

A head MRI scan has been quite acceptable to patients as they do not use radiation -just powerful magnets and radio waves Reply

MRI is also very useful to detect tumours. It usually gives the clearest picture of the brain of any type of scan and will almost certainly show up a brain Reply
