Scientists have created a transparent implant for the study of the living brain in real time
Scientists from the University of Minnesota have created a unique implant See-Shells for the skull, which will help to unravel the causes of Alzheimer's and Parkinson's diseases and that it is equally important to find ways to treat these and other dangerous diseases. The implant is a solid transparent enclosure created by using 3D-printing technology. According to the creators of the implant, the device helps to look at the head and see how your illness or injury affects the entire body as a whole. A detailed article on the development and research scientists has been published in the journal Nature Communications.
"The new device allows us to visualize brain activity and interact with large amounts of land surface, in this case - the entire cerebral cortex," - explains one of the authors of development Suhas Kodandaramayah.
Previously specialists could conduct monitoring only certain areas of the brain, to examine them in detail. New See-Shell is a tool to help learn what happens in one part of the brain and what the response to this activity takes place in the other. As the object of study and a candidate for the installation of a new implant scientists chose the brain of laboratory mice. First, they had a digital scan of the skull of rodents, and then print the 3D-printer of artificial transparent copies.
After that rodents spent surgical operation, during which the upper part of the mouse skull was removed. Its scientists have replaced the transparent implant. This manipulation allowed the researchers to observe the brain activity of the animals and to obtain images of the entire organ in real time.
As the authors point out the development, the implant was not rejected by the immune system of rodents, which allows for long-term monitoring of their brain.
"Such studies can not be performed on humans, but they are important for our understanding of the brain, so that we can improve the treatment of people who have an injury or disease of the brain," - says another author Timothy Ebner development.
