In Your Brain, It’s A Small World After All
CognitiveScience Wednesday, January 5, 2005 . This is a SciScoop post by Ricky James
The second common characteristic the researchers found was a strong “in-homogeneity” — many nodes had few connections and a very few nodes connected with many others. These “super-connected” nodes act as hubs, providing the networks with fast transmission of information.
“Overall, our initial results indicate that the brain networks share these two fundamental properties, implying that the underlying properties can be understood using the theoretical framework already advanced in the study of other, disparate, networks,” Chialvo said.
The research opens fascinating possibilities for future basic and applied studies to investigate the dynamics of brain states, particularly in cases of dysfunction — such as schizophrenia, Alzheimer’s disease and chronic pain — without requiring external markers.
Dante R. Chialvo, research associate professor of physiology at Northwestern University Feinberg School of Medicine, led the study, which appeared in the Dec. 31 online issue of the journal Physical Review Letters. The research group included scientists from the IBM T.J. Watson Research Center, Yorktown Heights, N.Y., and the University of Islas Baleares, Mallorca, Spain.
The studies were conducted by a multidisciplinary group of researchers at Feinberg, with funding from the National Institutes of Health; at the IMEDEA of University of Islas Baleares, Mallorca, Spain, with funding of the McyT of Spain; and at IBM T.J. Watson Research Center, Yorktown Heights, N.Y.

I had to read this article three times before I could get through it because “that darn tune” is now stuck in my head.
Plus I kept looking for something in the press release about why songs get stuck in our heads in the first place… :-)

At disneyland in California. My family went there when I was a kid.
Although I can’t remember anymore whether I liked or hated the song at that time…

…the ride in Florida. I think I probably cried my first time through… when I was all into the mommy thing.
But my current pique is not being able to remember the words to the VERSES.
