简介：
Overview
This study investigates potential biomarkers for epilepsy by comparing cerebrospinal fluid (CSF) and plasma samples taken from epileptic rats during spontaneous seizure monitoring using video-electroencephalogram (EEG). The approach aims to correlate the levels of different molecules with seizure activity while addressing concerns of sample quality and stress management in the animals.
