Using the eye-coil/magnetic field method, we measured the torsional vestibulo-ocular reflex (VOR) in ten subjects during active head rotations in roll at about 0.5 Hz. In the dark, regardless of instructions or mental effort, the gains (eye velocity/head velocity) had a mean value of around 0.61. When they viewed a visual display that was stationary, gains(More)
We studied the horizontal vestibulo-ocular reflex (VOR) during transient, high-acceleration (1900-7100 degrees/s2) head rotations in 4 human subjects. Such stimuli perturbed the angle of gaze and caused illusory movement of a viewed target (oscillopsia). The disturbance of gaze could be attributed to the latency of the VOR (which ranged from 6-15 ms) and(More)
We studied the ocular motor abnormalities in 4 patients chronically addicted to sniffing glue containing toluene. They showed acquired pendular nystagmus with horizontal and vertical components. One patient also showed saccadic oscillations. The pendular nystagmus may be a manifestation of a disturbance in brainstem-cerebellar connections secondary to the(More)
We examined 35 patients with unilateral cerebral lesions to determine the incidence of lateral deviation of the eyes under forcefully closed lids and the reliability of this sign in predicting the side of the lesion. Only patients with radiologically confirmed unilateral lesions were studied. Over 70% of patients had contralateral ocular deviation (Cogan's(More)
We describe an unusual case of digital neuropathy of the thumb due to compression of the median nerve in the distal forearm by an extruded ganglion cyst originating from the radio-scaphoid joint of the wrist. Electrophysiologically, both conduction slowing and block of median motor and sensory axons were present across the cyst. These changes improved after(More)
