Not very good, I couldn't get it to isolate the arteries of the brain.

Digital Atlas of the Human Brain
See the brain here: www.brain-map.org Not sure if this is really any use to us survivors except to question our doctors. Although maybe we could figure out the epigenics of neuron regeneration.
Scientists funded by Microsoft Corp. co-founder Paul Allen unveiled a $55 million computerized atlas of the human brain Tuesday, offering the first interactive research guide to the anatomy and genes that animate the mind.
A project of the Seattle-based Allen Institute for Brain Science, the online atlas offers researchers a powerful new tool to understand where and how genes are at work in the brain. That could help them find new clues to conditions rooted in the brain, such as Alzheimer's disease, autism and mental-health disorders like depression.
"Until now, a definitive map of the human brain at this level of detail simply hasn't existed," said Allan Jones, the nonprofit institute's chief executive. "For the first time, we have generated a comprehensive map of the brain that includes the underlying biochemistry."
The institute is making the atlas freely available at www.brain-map.org as a resource for scientists studying brain diseases, along with a set of computational tools to help them analyze the data for clues to conditions such as Alzheimer's disease, autism and mental-health disorders like depression.
Advances in the ability to probe the human brain have driven a renaissance in neuroscience in recent decades. The new online atlas is considered significant because it combines several reliable imaging techniques into one three-dimensional interactive archive that accurately maps overall anatomy, nerve structure, cell features and a comprehensive read-out of gene activity.
"The Allen atlas tells you where a gene is turned on in the brain and that's why it is important," said neurologist Jeffrey L. Noebels, who studies epilepsy at the Baylor College of Medicine in Houston.
Until now, researchers have been hard-pressed to link symptoms of the diseases they study to the biochemistry of genes that might be responsible for them.
"The location of where these genes are active is at the very center of understanding how brain diseases work," Dr. Noebels said.
The atlas has cataloged 1,000 anatomical landmarks in each of two normal adult brains, donated for research, and then linked those tissues to thousands of genes that must act in complex combinations for normal neural development and function. The atlas encompasses more than 100 million data points measuring how strongly or weakly different genes acted at each landmark.
As they assembled the brain images and genetic data, the researchers were surprised to discover that by this neural measure, any two people are 94% alike. Moreover, they found that more than 80% of all known human genes are actively at work in the brain.
This first edition of the atlas took four years to compile and, in its preliminary drafts, has already become a research tool for 4,000 scientists who have adopted it to probe brain biology. It builds on computer techniques that the Allen Institute developed during the creation of an interactive atlas of the mouse brain, which it released in 2006.
Yet the human brain atlas is far from finished. So far, the online archive is exclusively male. The researchers expect to add eight more brains to the archive by the end of next year, to better account for variations between people. The researchers said that, when completed, the online archive will include one or more female brains.
In the meantime, "We feel confident that we are giving a good average picture of the human brain to the people who are mining this data," said Dr. Jones.

Allen Institute for Brain Science
A thin section of human brain tissue was used to help compile the Allen Insitute's brain atlas in Seattle.
Scientists have unveiled a computerized atlas of the human brain that charts the underlying biochemistry of the mind. WSJ's Robert Lee Hotz talks with Kelsey Hubbard about how it was created and how researchers hope to use it.

3d anatomy and stroke rehab
I've always thought that survivors need to understand anatomy.
Anatomy of Pilates $199
http://www.primalpictures.com/Anatomy_for_Pilates.aspx
demo and free trial here
http://www.anatomy.tv/
My OT had a copy of this and it looked fascinating. You could move various limbs and agonist and antagonist muscles would be color coded so you could tell what was working vs. relaxing. At the time it only cost $80 but since my computer didn't have a DVD drive I didn't get it. It was great to see muscles in 3d rather than just flat depictions in an anatomy book.
This site also has demos and a free trial http://www.muscleandmotion.com/
I haven't gotten google body maps to work yet so that might be another possibility.
And you could stump your therapists.

anatomy and stroke rehab
Your OT and PT probably rattle off muscle names assuming that you know exactly what they are talking about. Of course you know that your calf muscle is triceps surae and is a pair of muscles located at the calf. The gastrocnemius and the soleus. The muscle you can't control that causes dropfoot is your Tibialis anterior muscle , otherwise known as lack of dorsiflexion. I could keep going but the point here is that having an understanding of what muscles are problematic is needed in order to mentally imagine and neuroplastically move control to a new area. The best book I found for this is Anatomy of Movement by Blandine Calais-Germain This one came recommended from my OT. It helps me visualize what muscles are being used for what movements and has some excellent diagrams. Bodybuilding books would be a good second choice and available at all libraries.
If we ever get to a damage diagnosis where our doctors specify exactly what sections of the brain are damaged then our therapists could use that diagnosis along with anatomy diagrams to show you exactly what you need to work on. Either easy neuroplasticity, from the penumbra or the draining bleed area, or hard neuroplasticity, moving dead brain function control to another location. And if you are lucky and smart enough you won't canabalize your executive control to get back motor movement.
