Hagmann et al. use diffusion mapping techniques to provide some awesome summary graphics of connectivity networks of our cerebral cortex. Regions of the neocortex are linked by a dense network of neural pathways, with several distinct nodes, like airline hubs. Their data:
...provides evidence for the existence of a structural core in human cerebral cortex. This complex of densely connected regions in posterior medial and parietal cortex is both spatially and topologically central within the brain. Its anatomical correspondence with regions of high metabolic activity and with some elements of the human default network suggests that the core may be an important structural basis for shaping large-scale brain dynamics. The availability of single-participant structural and functional connection maps now provides the opportunity to investigate interparticipant connectional variability and to relate it to differences in individual functional connectivity and behavior.

OMG! I can't believe someone wrote a blog just for me! (Of course, I'm being facitious here - I'm not experiencing psychosis - LOL!)
ReplyDeleteAnyway, I'm a mental health counselor who uses information on brain processes to help my clients understand not only how their problems originated, but also how they can change their brains to work better.
Your blog will help me A LOT - and, of course, I always note where I get my information (gotta stay ethical, you know.)
If you want, please check out my blog at: http://mhrecoveryproject.blogspot.com
Great description of brain processes.
ReplyDeleteIt will be interesting to connect them to other aspects of life.
