title: Exteroceptive silent periods of temporalis muscle activity: correlation with neuropsychological findings.
abstract: The latency and duration of the early (ES 1) and late (ES 2) exteroceptive silent period of temporalis muscle activity were determined in 51 neurological patients. We investigated whether these electrophysiological parameters correlated with neuropsychological variables of the patients using standardized scores for personality index, state of well-being and physical symptoms. There were no correlations between personality traits and the electrophysiological parameters, while we found significant correlations between the duration of ES 2 and momentary psychological and physical well-being variables. Moreover, the score of the momentary well-being item 'general feeling of well-being' was demonstrated to moderate significantly the ES 2 duration (P = 0.018). Therefore, neuropsychological factors prove to be of great relevance to the exteroceptive silent periods of temporalis muscle activity.
