Nervous System as a 3-D Map: First Complete Map of Special Connections of Nerve Cells in Zebrafish.

He would be hard to understand how a city is organized without the knowledge of the course of all streets. The scientists face the same problem when trying to understand the operation of the brain. In the case of vertebrates, we have only fragmentary knowledge whose the nervous cells send their connections, supposed axons, in certain regions of the brain. Such knowledge is particularly important to understand the operation of groups of nerves that send the axons to modulate the activity of circuits of the nerves in the moved away regions of the brain. One of these groups consists of the nervous cells that use the very small dopamine of the molecule like messenger to control many types of behavior. He is exact these neurons that die dull in those heartbroken ones with Parkinson' disease of s, a cause that demonstrates to the fundamental paper he plays in medicine.
An equipment of neurobiologists of the university of Freiburg, taken by professor dr. Wolfgang Driever of the faculty of Biology and the Dr. Olaf Ronneberger of the department of of computer science and the Dr. Rolando Nitschke including of the center for the Biology of systems (ZBSA), now has been successful in creating the first complete map of all the axons that use the dopamine like messenger in a vertebrate, that is to say in zebrafish model of the organism. The data identify all the possibilities of the projection, " supposed; projectome, " of each nervous cell for a messenger class in the nervous system that is of great importance for the medicine. The investigators cooperated close by with university' center of s for the Biology of systems (ZBSA) and BIOSS, center for the biological studies of signaling. The results were published the 25 of January of 2011 in the communications of the nature of the newspaper.
