A group of Japanese neuroscientists is trying to peer into the mind literally. They have devised a way to turn the brains opaque gray matter into a glassy, see-through substance.
The group, based at the government-financed Riken Brain Science Institute in Wako, Japan, has created an inexpensive chemical cocktail that transforms dead biological tissue from a colored mass into what looks like translucent jelly. Soaking brain tissue in the solution makes it easier for neuroscientists to see whats inside, a step they hope will uncover the physical basis of personality traits, memories and even consciousness.
Im very excited about the potential, said Dr. Atsushi Miyawaki, a researcher on the team, which published its discovery in the journal Nature Neuroscience.
The chemical solution patented under the name Scale, a phonetic approximation of the Japanese word for transparent could help neuroscientists map the brains underlying architecture, though that goal is still a distant one. At the moment, researchers are working to build such a map, called a connectome, of mouse brains, which are far less complex than human ones.
Ultimately, this mapping could be conducted on brains of different ages, Dr. Miyawaki said, providing a glimpse into how the organ develops and even how genetic differences might affect that development.
Dr. Miyawaki and his team have yet to try Scale on a human brain their lab works with mice but they plan to as soon as the gated process of obtaining a specimen is completed. He expects that the transparency solution will work just as well as it does on mouse brains.
Dr. Jeff Lichtman, a neuroscientist at Harvard University who is involved with the Human Connectome Project a multi-institution effort to map a mouse brain, and then a human one thinks that Scale shows...

The evolutionary stages of the Liberal brain??

Not mutually exclusive concepts....
Ha ha ha.
I know their secret sauce.
We used to use it on boiled eggs to turn them into superballs.
The bonus is that these scientists will be able to bounce those brains like super balls all over the Lab.
Perhaps the most transparent administration in American history has a brain they aren’t using available to donate?
FReepmail me if you want on or off my health and science ping list.
Hopefully this stuff does not dissolve away more details than it reveals. Why some kind of computed tomography couldn’t be used on the original specimen — and there’s no danger of overexposing it because it’s not living — is a question to me.
"Because it clarifies tissue without removing water, the solution sustains genetically introduced cell labels used to differentiate one neuron from the next in a wet environment like the one in which they originally evolved. The labels are made of proteins that come from jellyfish and corals."
"Scale is not difficult to make: It is a cheap mixture of urea (found in urine and fertilizer), glycerol and detergent."
IMHO, that's beyond the resolution of computed tomography.
From the quotes in the Times' article, they're using two naturally found molecules and the detergent in an aqueous solution to get images below the level individual neurons with the aid of fluorescent proteins, IMHO.
Seems a stretch like attempting to discover a physical basis for the soul.
While it might strike some as a metephysical quest, the dopaminergic system is involved in personality traits and memory, at least. Consciousness is vital for survival, e.g. fight or flight.
Check a search of "dopamine receptors" and "fluorescent proteins." (That period is there only for punctuation, not searching.)
