Objective: Cataplexy is defined as episodes of sudden, transient loss of voluntary muscle tone usually triggered by positive emotional stimuli. Due to the triggering factors, involvement of emotion-processing structures such as the amygdala and limbic system was suggested. Although electrophysiologically hypersynchronous paroxysmal slow wave activities were reported during cataplexy attacks, the involved area was not clear. In this study we examined functional couplings by using coherence analysis to investigate electrophysiological data among the involved brain regions during cataplexy attacks in adult patients.
