To examine how people deal with perceivable consequences of their voluntary actions, we recorded event-related potentials (ERPs) during a self-paced, two-choice random generation task. Sixteen participants were asked to press one of two buttons randomly at a regular but self-selected interval of once per 1-2 s. Each button press produced either a 1000-Hz or(More)
To examine how people perceive their action effects and how they learn by experience, we recorded event-related potentials (ERPs) during a self-paced, random generation task. Sixteen participants pressed one of two buttons randomly with a self-selected regular pace once per 1–2 s. Each button press triggered either a 1000 Hz or a 2000 Hz tone. Five blocks(More)
Temporary tinnitus and/or hearing loss elicited by contraction of facial mimetic muscles are often observed on the affected side in patients recovering from facial nerve paralysis and in those with facial spasm. In order to clarify the mechanism of this phenomenon, changes in auditory threshold and middle ear compliance during voluntary contraction of(More)
Two small facial neurinomas located in the horizontal portion were presented to demonstrate the clinical features, diagnostic evaluation, and surgical treatment. These two cases show the early state of facial neurinoma and suggest the mechanism of facial paralysis by facial neurinoma. Facial nerve decompression is recommended for Bell's palsy unresponsive(More)
