According to a study released on Friday, the so-called perineuronal tissue was first discovered in 1893 by Italian neurobiologist Camillo Golgi, but their role is unknown until the team at the Carilion Institute of Virginia State University is now complete. which regulates electrical impulses in the brain.
When these nets are destroyed, epilepsy attacks can occur, as they found when they investigated the brains of mice with very aggressive brain tumors called glioblastomas.
This is the only cancer that cannot spread because it is limited by the skull. Therefore, it secretes large amounts of a neurotransmitter called glutamate which kills the surrounding cells to allow the tumor to grow.
Scientists at Virginia Tech also found that tumors invade the net by dissolving it, making it difficult to regulate electrical impulses in the brain, which can then experience epileptic seizures.
Epilepsy researcher H. Steven White said the team's findings led by biologist Harald Sontheimer might apply to other forms of epilepsy obtained.
"This study shows a possible way to modify the development and development of epilepsy, which will reduce interference for patients," he said.
More than 50 million people worldwide suffer from epilepsy, according to the World Health Organization. About one third of patients do not respond to existing treatments.
