A report in the Journal of Neuroscience reported on advances made in research into ways of 'shutting off seizures'.
Researchers from Krasnow Institute for Advanced Study at George Mason University in Fairfax, Virginia, took specially treated slices of rat brain and used them in an electrical circuit. The circuit sensed when the slices of brain were firing in the same way as a seizure and then shut off the seizure by applying weak electric fields to the slices. Once this occurred, the researchers reduced the strength of the electric field until the next seizure occurred.
The researchers are currently working on desigining a device to be placed on the surface of the brain, and hope to apply in the next year to start clinical tests for safety.
