 Researchers cut thin slices of a brain using a tool called a microtome.

3-D model shows brain in finer detailA group of international researchers announced Thursday that they have created a three-dimensional model of the human brain in unprecedented resolution. It's called BigBrain. "BigBrain is the first ever brain model in 3-D, which really presents a realistic human brain with all the cells and all the structures of a human brain," said Karl Zilles, senior professor of the Julich Aachen Research Alliance, in a press briefing. The research is being published in the journal Science. This model is akin to a scaffold into which information about the living brain can be inserted. It's a reference to provide framework for research in many directions, such as how the brain is organized. BigBrain will be made freely available to the public. Researchers who study neuroscience can use BigBrain to simulate how a brain develops normally or how it degenerates in conditions such as Alzheimer's disease, said Alan Evans of the Montreal Neurological Institute at McGill University and senior author on the paper. It makes it possible to model how the brain would perform without certain key connections or structures, investigating the process of age-related impairment. "We can understand more about how the brain works if we can model it inside a powerful computing system," Evans said. An Alzheimer's researcher could also use BigBrain to look into the details of the hippocampus, a seahorse-shaped structure in the brain crucial for memory, Zilles said. Creating such a model of the human brain is substantially more difficult than creating a similar model for a mouse. The human cerebral cortex volume is about 7,500 times larger than that of a mouse cortex. The human brain has 53,000 times more white matter than that of a mouse. The researchers assembled this model based on the brain of a single person: A 65-year-old woman. They cut her brain into more than 7,000 sections at a thickness of .02 millimeters, and stained each of these pieces to detect cell bodies. Then each section was digitized. The BigBrain will eventually be able to integrate molecular data into the model, something the researchers are presently working on. "Only if we understand the level of molecular distribution patterns and expression patterns in the brain, and connect it with the detailed anatomy, then we can really understand the relationship between structure and function in the human brain," Zilles said. The size of the data is mind boggling: It's on the order of a terabyte, which is about 100,000 times larger than a typical MRI, Evans said. The researchers have also been in touch with the Allen Institute for Brain Science, which has its own brain atlas data portal, about integrating the Allen data with BigBrain. It's important for the field of neuroscience to have one brain model that serves as the common basis for scientific discussions, Zilles said. Ultimately, researchers would like to have a model with a resolution of one micrometer, such that details at the single-cell level would be revealed. The research is part of the Human Brain Project, a 1-billion euro European program to recreate the human brain inside a supercomputer.

Hello there, I think your site could possibly be having browser compatibility issues. Whenever I take a look at your web site in Safari, it looks fine however, if opening in IE, it's got some overlapping issues. I merely wanted to provide you with a quick heads up! Other than that, wonderful blog!

Aw, this was a very nice post. Spending some time and actual effort to make a top notch article… but what can I say… I put things off a whole lot and don't seem to get anything done.

An impressive share! I've just forwarded this onto a friend who had been doing a little research on this. And he in fact ordered me dinner simply because I found it for him... lol. So let me reword this.... Thanks for the meal!! But yeah, thanks for spending the time to discuss this issue here on your web site.

Having read this I thought it was really informative. I appreciate you finding the time and energy to put this informative article together. I once again find myself spending way too much time both reading and leaving comments. But so what, it was still worthwhile!

The very next time I read a blog, I hope that it doesn't fail me just as much as this one. After all, Yes, it was my choice to read, however I genuinely believed you would have something interesting to say. All I hear is a bunch of complaining about something you could fix if you were not too busy seeking attention.

Iím amazed, I have to admit. Seldom do I come across a blog thatís equally educative and amusing, and without a doubt, you've hit the nail on the head. The issue is something which too few people are speaking intelligently about. Now i'm very happy that I found this during my hunt for something concerning this.
