Event-Related Synchronization/Desynchronization for Evaluating Cortical Response Detection Induced by Dynamic Visual Stimuli

摘要: In the present work, Event-Related Synchronization and Desynchronization (ERD/ERS) index was used for evaluating cortical response to dynamic visual stimulation in an postural control protocol. EEG signals (O1, P3, P4 O2 derivations) of 33 healthy subjects were acquired during stabilometric test. The trials conducted with subject observing a white wall (WW) virtual scene on static (SS) (DS) conditions. power spectra estimates compared using Spectral F-Test (SFT, α = 0.05 Bonferroni correction) ERD/ERS index. SFT results indicate no difference between contribution WW SS, decreased within alpha band DS all derivations. allowed successfully detecting above 83% desynchronization stimulation. Moreover, it also promotes instability. This finding indicates potentiality technique studies assessed by
