Recent neurophysiological studies showed that patients with psychiatric disorders demonstrated abnormalities in sensorimotor functions addition to cognitive deficits. These findings intrigued us investigate whether trait anxiety, a persistent inclination towards being anxious multiple contexts, would affect motor cortical functions. Event-related desynchronization (ERD) and event-related synchronization (ERS) of α β oscillations are associated movement execution termination, respectively. However, no study has comprehensively examined the effects anxiety on ERD ERS. Therefore, this aimed determine how influences these oscillations. Twenty subjects (top 10% score distribution from 400 college students) higher (HTA) 20 (bottom same sample) lower (LTA) were recruited perform Go-Nogo task during electroencephalographic recordings. ERS Go responses compared between two groups. The associations each group also examined. Neither nor power changes significantly different LTA HTA Interestingly, significant correlation ERS/β was found individuals LTA; however, such functional coupling not present HTA.
