Observation of EEG coherence after repetitive transcranial magnetic stimulation

Objective: The effects before and after repetitive transcranial magnetic stimulation (rTMS) on EEG activity were investigated. Methods: Nineteen healthy subjects received two trains (10 Hz, 100% of motor threshold, 3 s/train) of rTMS to the left frontal area. Directed coherence and ordinary coherenc...

Zusammenfassung:	Objective: The effects before and after repetitive transcranial magnetic stimulation (rTMS) on EEG activity were investigated. Methods: Nineteen healthy subjects received two trains (10 Hz, 100% of motor threshold, 3 s/train) of rTMS to the left frontal area. Directed coherence and ordinary coherence were calculated from EEG epochs recorded before and after (1~3 and 3~5 min) rTMS. The results were compared and demonstrated on maps. Results: Directed coherence between cortical areas increased after rTMS ( F=5.62, P
