The Authors Reply We appreciate the clinical and radiological comments by Tsuda, concerning partial oculomotor fascicular paresis in our patient (1). He proposed the possibility that the left medial longitudinal fasciculus (MLF) syndrome and palsy of the right inferior rectus muscle were present in our patient. The red glass test and Hess chart were performed in our patient. These results revea...

Keeping the finger pointing at an Earth-fixed object during body displacements can be achieved if compensatory arm movements counteract the effect of the rotation on the hand's position in space. Here we investigated the fusion of signals that originated from systems having different neurophysiological properties (i.e., the visuo-oculomotor and vestibular systems) in the production of such comp...

We describe a case of acute oculomotor nerve palsy caused by a ruptured middle cerebral artery (MCA) aneurysm. A 59-year-old female presenting with headache and nausea was admitted to our hospital. Her consciousness was alert, and had no other neurological deficit without left oculomotor nerve palsy. A computed tomography (CT) showed SAH extending from left sylvian cistern to basal cistern. CT ...

Eye movements in vertebrates are controlled by six extraocular muscles innervated by three of the cranial nerves – the oculomotor, trochlear and abducens. Incorrect development of this wiring network can lead to eye movement disorders, such as the congenital condition Duane retraction syndrome (DRS), which results in squint (strabismus). In DRS patients, the abducens nerve is often absent, and ...

The current study investigated the role of the frontal eye fields (FEF) in the suppression of an unwanted eye movement ('oculomotor inhibition'). Oculomotor inhibition has generally been investigated using the antisaccade task, in which an eye movement to a task-relevant onset must be inhibited. Various lines of research have suggested that successful inhibition in the antisaccade task relies h...

Using PET and H215O, we investigated the cortical areas that merge two different ways of coding space in the cerebral cortex, those concerned with the oculomotor and the somatomotor space. Normal subjects performed a visuomotor task that required the spatial coding of visual stimuli in oculomotor space and of motor responses in somatomotor space. We manipulated the mapping of oculomotor and som...
