Brain Maps Online

Daily Science - atlases of DIGITAL of the brains of human, monkeys, dogs, cats, mice, birds and other animals were created on line and announced by researchers to center CPU of Davis for neurology.

Comprise the highest atlases of entirety-brain of resolution ever built, with more than 50 Terabyte of in line accessible from visual data of brain directly. The users can explore the brains of human and a variety of other species to one without preceding level of detail, of an overall picture of the brain to the fine details of the nerves and connections. The Web site also includes a continuation of the free tools and downloadable for navigation and analyzing data of brain.

The charts with high resolution will make it possible researchers to employ "virtual microscopy" to compare healthy brains with others, looking at the structure, the expression of gene and the distribution of various proteins. They will allow a better arrangement of the organization of the normal the brains, and could help of the researchers by identifying very quite morphological and chemical anomalies fundamental Alzheimer, neurological Parkinson and other diseases, Mikula known as.

To make the charts, the researchers started with sections of brain assembled on the microscope slides. These slides were swept to create files of image or "virtual slides," and assembled like tiles in made up images. The charts have a resolution of better than half has micrometer by Pixel, or 55.000 points per inch, with the virtual slides approaching 30 gigaoctets in the face each one.

Paper is published in the edition of March of the NeuroImage newspaper. The other authors above paper are Issac Trotts and stone of James, the two researchers in the center for neurology, and Edouard Jones, director of the center and a professor of psychiatry at Davis CPU. Work was placed by the national institutes of health.

The doctors have known of length on ghost pain. Ambroise Paré, French surgeon of the sixteenth century, described you in soldiers with the amputated members and suggested the pain originated in the brain. But to equal it is not today completely clear what causes the mysterious sensations, said Vilayanur Ramachandran, a neurologist in the university of California, San Diego.
Pettifer and the virtual adjustment less invader of the colleagues is modeled in the previous work of Ramachandran, that implied a cardboard box with a mirror in a side. In that method, a person feels in front of the box and the arm moves.
The reflection in the mirror appears to deceive the brain of the person in the thought of the reflected member is the accessory that lack that is moving.

Pettifer says that near 80 percents of all amputees they experience a certain malaise associated to a ghost member or sensations of the members-to slight of pains that throw or electrical unloadings. Some people feel as if their members are stirred up for above in impossible positions.
Others detect their tight fingers that they dig painful in his palms. The virtual reality could carry out the key to often facilitate the sensation agonizing of a member that lack that feels as if still it is there, the experts says.
“Four of the five patients who used our virtual system of the reality disclosed the significant reduction in pain,” said to Steve Pettifer, computer science in the university of Manchester in the United Kingdom.
