Chan JL, Kucyi A. What can fMRI tell us about functional variability in the oculomotor system and saccade performance? J Neurophysiol 107: 2295–2297, 2012. First published January 18, 2012; doi:10.1152/jn.00724.2011.—Eye movement behavior is variable, and the brain’s oculomotor circuitry may not always function consistently. In a recent fMRI study, Ozyurt and Greenlee (2011) correlated the acti...

INTRODUCTION Recurrent oculomotor nerve palsies are extremely rare clinical conditions. CASE REPORT Here, we report on a unique case of a short-lasting recurrent unilateral incomplete external and complete internal oculomotor nerve palsy. The episodic palsies were probably caused by an ipsilateral mesencephalic metastasis of a breast carcinoma and occurred after successful brain radiation the...

Recent work shows that abrupt onsets reflexively capture attention and trigger saccades that compete with voluntary saccades. To test whether oculomotor capture occurs when no saccade is being planned, we measured fixational eye movements in the absence or presence of an abrupt onset at peripheral locations. We found no effect of abrupt onset location on the average pattern of eye movements dur...

We herein report the case of an 81-year-old woman with midbrain infarction causing pupil-sparing oculomotor nerve palsy with ipsilateral cerebellar ataxia. The lesion was located at the rostral end of the decussation of the superior cerebellar peduncle touching the dorsal side, further caudal and dorsal to causal lesions of Claude's syndrome, which presented as oculomotor palsy and contralatera...

Several neurological complications have been described after influenza vaccination. Oculomotor palsy has not been yet related with influenza vaccine. We report a 79-year-old man who developed an acute transient right oculomotor palsy two days after a routine influenza vaccination, for which no other cause was identified. There was no evidence of diabetes, glucose intolerance, high blood pressur...

Accurate oculomotor control is one of the essential pre-requisites of successful visuomotor coordination. Given the variable nonlinearities of the geometry of binocular vision as well as the possible nonlinearities of the oculomotor plant, it is desirable to accomplish accurate oculomotor control through learning approaches. In this paper, we investigate learning control for a biomimetic active...
