Researchers at the Norwegian University of Life Sciences (UMB) have published a study on a new method for analysing electrical activity in the brain. The study was published in the journal Neuron. The method may result in new developments in interpreting EEG measurement and diagnosing and treating brain illnesses, according to a university press release.
The study details how doctors and researchers can interpret brain cell signals, focusing on low frequency signals called “local field potential” (LFP). The researcher used methods from physics, mathematics and informatics and the Stallo supercomputer located in Tromsø for the study.
While doctors can relate signal shapes in the brain to different brain diseases, they haven’t had much knowledge on how these signals are formed, according to the press release. The new mathematical model developed by the researchers details the connection between the nerve activity and the electrical signal recorded by an electrode, according to Professor Gaute Einevoll at the Department of Mathematical Sciences and Technology (IMT) at UMB.
Electrodes can be used to measure brain cell activity related to seizures in epilepsy patients. The technique could be used to measure LFP signals in order to detect a seizure and stop it by injecting a suitable electrical current, according to Einevoll.
