From inter-ictal to pre-ictal, SFG (BA10) showed maximum decreased delta oscillations. Results: Compared with the resting-state EEG data of the HC group, the EEG data from AE patients during inter-ictal periods showed decreased alpha oscillations in regions involving the superior frontal gyrus (SFG) (BA11). Functional independent components analysis (ICA) was carried out using the LORETA KEY tool. For the HC group, five 10-s resting-state EEG epochs were extracted. For AE patients, five epochs of 10-s EEG data in inter-ictal, pre-ictal, and post-ictal states were collected. Each included subject underwent a 2-h and 19-channel video EEG examination. Methods: 21 AE patients with a current high frequency of seizures and 21 sex- and age-matched health control (HC) who reported no history of neurological or psychiatric disorders and visited the hospital for routine physical examinations were included. Objective: To investigate the dynamical brain network changes before and after an absence seizure episode in absence epilepsy (AE). ![]() ![]() 3Department of Neurology, Suining Central Hospital, Suining, China.2Laboratory of Neurological Diseases and Brain Function, Luzhou, China.1Department of Neurology, The Affiliated Hospital of Southwest Medical University, Luzhou, China.Zhiye Li 1,2 † Jialing Huang 1,2 † Wei Wei 1,2 Sili Jiang 3 Hong Liu 1,2 Hua Luo 1,2 * Jianghai Ruan 1,2 * ![]()
