Very huge step forward for brain sensory mapping.

Data from functional magnetic resonance imaging (fMRI) have provided eye-popping pictures of the way the brain is wired, and allowed neuroscientists and laypeople alike to view intricate anatomical and functional connections between regions of the brain. But what if a new tool could be applied to MRI and other data, to listen to the way the brain works and how it is forged with connections?

An emerging effort to “sonify” imaging data is taking root at UT Dallas’ Center for Vital Longevity, in the lab of Dr. Gagan Wig. The approach, now funded by the Defense Advanced Research Projects Agency (DARPA), allows data to be represented by sounds from which a trained listener might be able to discern patterns of brain connectivity not readily seen in available visualization strategies.

Wig, an assistant professor in the School of Behavioral and Brain Sciences, is working with his UT Dallas colleagues Dr. Roger Malina, Arts and Technology Distinguished Chair, Scot Gresham-Lancaster, assistant professor in the sound design program in the School of Arts, Technology, and Emerging Communication, and a mix of scientists, computer programmers and artists to translate data to sight and sound.

I do know that a certain form of Glioblastoma does run in families; however, 3 sisters and all so young is a tragedy.

BONITA SPRINGS, Florida — A Florida family is remembering another child whose life was taken too soon.

Ten-year-old Isabella Mading died on Saturday, February 6th after her year-long battle with a rare form of brain cancer — the same disease that killed her older brother in 2010 and her older sister 2013.

Enough said; hope folks are paying attention when re-creating those “Cognitive Thinking” skills in AI; otherwise, they miss the boat with almost 60% of the world’s population.

NEW YORK: Male and female behavioural differences correlate with their different brain networks, say researchers, including one of Indian origin.

Structural differences in the brain may relate to male and female behaviour differences such as men being more likely to be better at learning and performing a single task at hand and women being more likely to exhibit superior memory and social cognition skills, the study said.

“Our results suggest a synchrony between sex-related differences in the brain network and behaviour,” said senior study author Ragini Verma, associate professor at Perelman School of Medicine at University of Pennsylvania in the US.

Interesting. What do you think of this?

A mammal brain has been defrosted from cryogenic storage in an almost perfect state for the first time. This breakthrough, accomplished using a rabbit brain, brings us one – albeit tiny – step closer to the prospect of reanimating a human brain that has been cryogenically preserved.

After death, organs begin to decay, but we can delay this by cooling these tissues, just like freezing food. But in the same way that a frozen strawberry becomes soggy when defrosted, it is difficult to perfectly preserve mammals at cold temperatures. We, and strawberries, contain large amounts of water, which freezes into ice crystals that damage cells.

Cryoprotectants can prevent this ice damage, working like medical-grade antifreezes and preventing organs from freezing. This works in small worms and rabbit kidneys, but it needs to be administered quickly, which usually causes brains to dehydrate and shrink.
