We studied the spatial characteristics of 45 vestibular-only (VO) and 12 vestibular-plus-saccade (VPS) neurons in two cynomolgus monkeys using angular rotation and static tilt. The purpose was to determine the contribution of canal and otolith-related inputs to central vestibular neurons whose activity is associated with the central velocity storage integrator. Lateral canal-related neurons res...

BACKGROUND We studied the anomalous head postures (AHPs) of five monocular viewing patients and investigated the possible causes and the appropriate surgical strategies to correct each condition. METHODS Five patients with acquired visual loss in one eye and associated head tilt and/or turn were examined and treated for correcting the head posture according to the etiology of their respective...

BACKGROUND The effect of orthostatic stress on dynamic cerebral autoregulation (CA) in normal subjects and patients with recurrent vasovagal syncope (VVS) is unclear. This study assessed the dynamic CA responses of both groups to head-up tilt. METHODS AND RESULTS Seventeen patients with recurrent VVS and 17 pair-matched control subjects underwent 70 degrees head-up tilt for up to 30 minutes. ...

During surgical laparoscopy, total hepatic blood flow (THBF) may be modified by CO2insufflation, changes of tilt, ventilation with high tidal volume, hypercapnia, and anesthesia, but little information is available on the THBF during the procedure. To investigate the changes of hepatic blood flow following the combination of abdominal CO2 insufflation and changes of tilt, we measured mean arter...

Autonomic nervous system Posture Blood pressure Head up tilt Original Article AIMS: Orthostatic stress is commonly utilized to evaluate the cardiovascular autonomic function. This is done by Head Up Tilt (HUT).. Tilt table test is a standardized, physiological, clinically relevant stimulus that challenges the cardiovascular regulation. By the performance of head up tilt, it is possible to asses...

Aim: We aimed to detect the utility of head up tilt test with video electroencephalography (EEG) in children with unexplained, recurrent loss of consciousness episodes. Method: Video EEG were recorded during the head up tilt test. The test was terminated if syncope or presyncope with 30% decrease in heart rate and/or systolic blood pressure occurred. Regarding encephalography, average amplitude...

Forearm rotation occurs around an axis connecting the center of the radial head and the fovea of the distal ulna. The purpose of the present study was to demonstrate the usefulness of the difference between forearm and proximal radial axis in the treatment of malunited forearm fractures. We reviewed the results of eight corrective osteotomies for malunited fractures of the forearm without dislo...
