Ophthalmopathy related to thyroid disease is due mainly to diffuse periorbital or eye muscle inflammation. It is more common in Grave’s hyperthyroidism and rare in Hashimoto’s hypothyroidism. Here we report a case of recurrent oculomotor nerve palsy associated with autoimmune hypothyroidism. Brain MRI revealed enhancement of the oculomotor nerves. Despite thyroid hormone replacement therapy, oc...

The mammalian oculomotor nucleus receives a strong γ-aminobutyric acid (GABA)ergic synaptic input, whereas such projections have rarely been reported in fish. In order to determine whether this synaptic organization is preserved across vertebrates, we investigated the GABAergic projections to the oculomotor nucleus in the goldfish by combining retrograde transport of biotin dextran amine, injec...

Oculomotor control in a humanoid robot faces similar problems as biological oculomotor systems, i.e. the stabilization of gaze in face of unknown perturbations of the body, selective attention, stereo vision, and dealing with large information processing delays. Given the nonlinearities of the geometry of binocular vision as well as the possible nonlinearities of the oculomotor plant, it is des...

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 ...

     Multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative disorder of the central nervous system (CNS) of unknown etiology. Isolated oculomotor nerve palsy is found rarely in children with MS. We present a case of MS in 10-year-old boy, who had bilateral ptosis associated with medial gaze restriction. The extraocular muscle examination demonstrated bilateral adduction pa...

When two objects such as billiard balls collide, observers perceive that the action of one caused the motion of the other. We have previously shown (Badler, Lefèvre, & Missal, 2010) that this extends to the oculomotor domain: subjects make more predictive movements in the expected direction of causal motion than in a noncausal direction. However, predictive oculomotor and reactive psychophysica...

There is little consensus regarding the specific processes responsible for encoding, maintenance, and retrieval of information in visuo-spatial working memory (VSWM). One influential theory is that VSWM may involve activation of the eye-movement (oculomotor) system. In this study we experimentally prevented healthy participants from planning or executing saccadic eye-movements during the encodi...
