In Memorial-Hermann hospital at the University of Texas Medical Center in Houston, Neurosurgeon Nitin Tandon visits 26-year-old epilepsy patient Tyler.
Dr. Tandon has placed platinum Coach Outlet Store Online electrodes on the surface of Tyler's brain so that he can monitor electrical signals when Tyler is having a seizure
"Before we can even understand how we would come up with prosthetic devices that we may be able to use to supplant certain brain functions that have been lost, we have to model those and understand those Michael Kors Purses at a computational level," Tandon said.
Since such studies contribute to the understanding of epilepsy, Tyler is a willing participant. "I think the more education there is about it, the better off the Coach Outlet Online rest of the people will be," Tyler said.
Patients like Tyler have also contributed to a study of how the brain forms memories of events in terms of time and space. It has Coach Factory Outlet Online been a puzzle how the brain communicates both with the "where" and the "when" areas, Tandon said.
Dr. Tandon had patients with implanted electrodes carry out learning tasks that involved both space and time Michael Kors Handbags Outlet to see how the brain handled the information.
"The way the brain does this, that it accomplishes communication with these two different areas at the same time, is by using two different frequencies coming coach outlet store from the same part of the brain, the hippocampus," he said.
The hippocampus is a structure on the lower side of the brain that regulates the formation of memories that are then stored in Coach Outlet separate areas of the brain.
It is very much like saying that you have a radio station that is sending out signals to two different groups of listeners at the same time and it michael kors does that by using two different frequencies, Tandon said.
At the University of California, Davis, neuroscientist Arne Ekstrom analyzed data from the brain scans -- applying graph theory techniques used to study information flow. Michael Kors Outlet Store He, Tandon and their colleagues hope to pursue this investigation in future studies.
Since memory loss is one of the problems associated with epilepsy, Dr. Tandon says this research holds promise for epileptics Coach Factory Outlet store as well. We are setting ourselves up for being able to restore memory dysfunction much better than we have with these electrodes in patients with epilepsy and also, potentially, at some point, being able Coach Outlet Stores to restore normal network dynamics, Tandon said
