Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)
The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.
Traumatic injuries to the OCULOMOTOR NERVE. This may result in various eye movement dysfunction.
Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.
Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to injury of the pupillary fibers in the oculomotor nerve, in acute angle-closure glaucoma, and in ADIE SYNDROME.
The 4th cranial nerve. The trochlear nerve carries the motor innervation of the superior oblique muscles of the eye.
The 6th cranial nerve which originates in the ABDUCENS NUCLEUS of the PONS and sends motor fibers to the lateral rectus muscles of the EYE. Damage to the nerve or its nucleus disrupts horizontal eye movement control.
Unequal pupil size, which may represent a benign physiologic variant or a manifestation of disease. Pathologic anisocoria reflects an abnormality in the musculature of the iris (IRIS DISEASES) or in the parasympathetic or sympathetic pathways that innervate the pupil. Physiologic anisocoria refers to an asymmetry of pupil diameter, usually less than 2mm, that is not associated with disease.
Nerve fibers which project from parasympathetic ganglia to synapses on target organs. Parasympathetic postganglionic fibers use acetylcholine as transmitter. They may also release peptide cotransmitters.
Drooping of the upper lid due to deficient development or paralysis of the levator palpebrae muscle.

Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and ESOTROPIA. Common conditions associated with nerve injury include INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; ISCHEMIA; and INFRATENTORIAL NEOPLASMS.
An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.

Constriction of the pupil in response to light stimulation of the retina. It refers also to any reflex involving the iris, with resultant alteration of the diameter of the pupil. (Cline et al., Dictionary of Visual Science, 4th ed)
Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.
A form of ocular misalignment where the visual axes diverge inappropriately. For example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. An exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.
Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE.

A form of bacterial meningitis caused by MYCOBACTERIUM TUBERCULOSIS or rarely MYCOBACTERIUM BOVIS. The organism seeds the meninges and forms microtuberculomas which subsequently rupture. The clinical course tends to be subacute, with progressions occurring over a period of several days or longer. Headache and meningeal irritation may be followed by SEIZURES, cranial neuropathies, focal neurologic deficits, somnolence, and eventually COMA.

Recovery of the vestibulocolic reflex after aminoglycoside ototoxicity in domestic chickens. (1/219)

Avian auditory and vestibular hair cells regenerate after damage by ototoxic drugs, but until recently there was little evidence that regenerated vestibular hair cells function normally. In an earlier study we showed that the vestibuloocular reflex (VOR) is eliminated with aminoglycoside antibiotic treatment and recovers as hair cells regenerate. The VOR, which stabilizes the eye in the head, is an open-loop system that is thought to depend largely on regularly firing afferents. Recovery of the VOR is highly correlated with the regeneration of type I hair cells. In contrast, the vestibulocolic reflex (VCR), which stabilizes the head in space, is a closed-loop, negative-feedback system that seems to depend more on irregularly firing afferent input and is thought to be subserved by different circuitry than the VOR. We examined whether this different reflex also of vestibular origin would show similar recovery after hair cell regeneration. Lesions of the vestibular hair cells of 10-day-old chicks were created by a 5-day course of streptomycin sulfate. One day after completion of streptomycin treatment there was no measurable VCR gain, and total hair cell density was approximately 35% of that in untreated, age-matched controls. At 2 wk postlesion there was significant recovery of the VCR; at this time two subjects showed VCR gains within the range of control chicks. At 3 wk postlesion all subjects showed VCR gains and phase shifts within the normal range. These data show that the VCR recovers before the VOR. Unlike VOR gain, recovering VCR gain correlates equally well with the density of regenerating type I and type II vestibular hair cells, except at high frequencies. Several factors other than hair cell regeneration, such as length of stereocilia, reafferentation of hair cells, and compensation involving central neural pathways, may be involved in behavioral recovery. Our data suggest that one or more of these factors differentially affect the recovery of these two vestibular reflexes.  (+info)

Microstimulation of the lateral wall of the intraparietal sulcus compared with the frontal eye field during oculomotor tasks. (2/219)

We compared the effects of intracortical microstimulation (ICMS) of the lateral wall of the intraparietal sulcus (LIP) with those of ICMS of the frontal eye field (FEF) on monkeys performing oculomotor tasks. When ICMS was applied during a task that involved fixation, contraversive saccades evoked in the LIP and FEF appeared similar. When ICMS was applied to the FEF at the onset of voluntary saccades, the evoked saccades collided with the ongoing voluntary saccade so that the trajectory of voluntary saccade was compensated by the stimulus. Thus the resultant saccade was redirected and came close to the endpoint of saccades evoked from the fixation point before the start of voluntary saccade. In contrast, when ICMS was applied to the LIP at the onset of voluntary saccades, the resultant saccade followed a trajectory that was different from that evoked from the FEF. In that case, the colliding saccades were redirected toward an endpoint that was close to the endpoint of saccades evoked when animals were already fixating at the target of the voluntary saccade. This finding suggests that the colliding saccade was directed toward an endpoint calculated with reference to the target of the voluntary saccade. We hypothesize that, shortly before initiation of voluntary saccades, a dynamic process occurs in the LIP so that the reference point for calculating the saccade target shifts from the fixation point to the target of a voluntary saccade. Such predictive updating of reference points seems useful for immediate reprogramming of upcoming saccades that can occur in rapid succession.  (+info)

Oculomotor tracking in two dimensions. (3/219)

Results from studies of oculomotor tracking in one dimension have indicated that saccades are driven primarily by errors in position, whereas smooth pursuit movements are driven primarily by errors in velocity. To test whether this result generalizes to two-dimensional tracking, we asked subjects to track a target that moved initially in a straight line then changed direction. We found that the general premise does indeed hold true; however, the study of oculomotor tracking in two dimensions provides additional insight. The first saccade was directed slightly in advance of target location at saccade onset. Thus its direction was related primarily to angular positional error. The direction of the smooth pursuit movement after the saccade was related linearly to the direction of target motion with an average slope of 0.8. Furthermore the magnitude and direction of smooth pursuit velocity did not change abruptly; consequently the direction of smooth pursuit appeared to rotate smoothly over time.  (+info)

Effect of reversible inactivation of macaque lateral intraparietal area on visual and memory saccades. (4/219)

Previous studies from our laboratory identified a parietal eye field in the primate lateral intraparietal sulcus, the lateral intraparietal area (area LIP). Here we further explore the role of area LIP in processing saccadic eye movements by observing the effects of reversible inactivation of this area. One to 2 microl of muscimol (8 mg/ml) were injected at locations where saccade-related activities were recorded for each lesion experiment. After the muscimol injection we observed in two macaque monkeys consistent effects on both the metrics and dynamics of saccadic eye movements at many injection sites. These effects usually took place within 10-30 min and disappeared after 5-6 h in most cases and certainly when tested the next day. After muscimol injection memory saccades directed toward the contralesional and upper space became hypometric, and in one monkey those to the ipsilesional space were slightly but significantly hypermetric. In some cases, the scatter of the end points of memory saccades was also increased. On the other hand, the metrics of visual saccades remained relatively intact. Latency for both visual and memory saccades toward the contralesional space was increased and in many cases displayed a higher variance after muscimol lesion. At many injection sites we also observed an increase of latency for visual and memory saccades toward the upper space. The peak velocities for memory saccades toward the contralesional space were decreased after muscimol injection. The peak velocities of visual saccades were not significantly different from those of the controls. The duration of saccadic eye movements either to the ipsilesional or contralesional space remained relatively the same for both visual and memory saccades. Overall these results demonstrated that we were able to selectively inactivate area LIP and observe effects on saccadic eye movements. Together with our previous recording studies these results futher support the view that area LIP plays a direct role in processing incoming sensory information to program saccadic eye movements. The results are consistent with our unit recording data and microstimulation studies, which suggest that area LIP represents contralateral space and also has a bias for the upper visual field.  (+info)

Isodirectional tuning of adjacent interneurons and pyramidal cells during working memory: evidence for microcolumnar organization in PFC. (5/219)

Studies on the cellular mechanisms of working memory demonstrated that neurons in dorsolateral prefrontal cortex (dPFC) exhibit directionally tuned activity during an oculomotor delayed response. To determine the particular contributions of pyramidal cells and interneurons to spatial tuning in dPFC, we examined both individually and in pairs the tuning properties of regular-spiking (RS) and fast-spiking (FS) units that represent putative pyramidal cells and interneurons, respectively. Our main finding is that FS units possess spatially tuned sensory, motor, and delay activity (i. e., "memory fields") similar to those found in RS units. Furthermore, when recorded simultaneously at the same site, the majority of neighboring neurons, whether FS or RS, displayed isodirectional tuning, i.e., they shared very similar tuning angles for the sensory and delay phases of the task. As the trial entered the response phase of the task, many FS units shifted their direction of tuning and became cross-directional to adjacent RS units by the end of the trial. These results establish that a large part of inhibition in prefrontal cortex is spatially oriented rather than being untuned and simply regulating the threshold response of pyramidal cell output. Moreover, the isodirectional tuning between adjacent neurons supports a functional microcolumnar organization in dPFC for spatial memory fields similar to that found in other areas of cortex for sensory receptive fields.  (+info)

MR imaging of Dejerine-Sottas disease. (6/219)

We report the MR findings in two patients with clinically and histologically proved Dejerine-Sottas disease. One patient had spinal involvement with multiple thickened and clumped nerve roots of the cauda equina; the second had multiple enlarged and enhancing cranial nerves. Although these findings are not specific for Dejerine-Sottas disease, they are suggestive of the diagnosis, which is further corroborated with history and confirmed with sural nerve biopsy and laboratory studies.  (+info)

Stereotactic radiosurgery for cavernous sinus cavernous hemangioma--case report. (7/219)

A 40-year-old female presented with cavernous sinus cavernous hemangioma manifesting as left abducens and trigeminal nerve pareses. Magnetic resonance imaging revealed a left cavernous sinus tumor. The tumor was partially removed. Histological examination of the specimen confirmed cavernous hemangioma. Radiosurgery was performed using the gamma knife. The tumor markedly decreased in size after radiosurgery and morbidity was avoided. Cavernous sinus cavernous hemangiomas may be difficult to treat surgically due to intraoperative bleeding and cranial nerve injury. Stereotactic radiosurgery can be used either as an adjunct treatment to craniotomy, or as the primary treatment for small cavernous sinus cavernous hemangioma.  (+info)

Model for the translational vestibuloocular reflex (VOR). (8/219)

The function of the translational vestibuloocular reflex (tVOR) and the angular vestibuloocular reflex (aVOR) is to stabilize images on the retina during translational and rotational motion, respectively. It has generally been assumed that these two reflexes differ in their central processing because they differ significantly in their primary afferent behavior and characteristics at the motor level. So far, models of the tVOR have focused on the type of processing that the primary afferent signal must undergo before reaching the neural integrator. Here, we propose a model that does not require any prefiltering. It is known that the eye plant requires signals in phase with velocity and position. We propose that the velocity signal is obtained directly from the neural integrator, whereas the position signal is obtained directly from the primary afferents synapsing onto the oculomotor nuclei. This design proved sufficient to simulate eye movements in response to translational motion.  (+info)

In a companion paper, we reported that the goldfish oculomotor neural integrator could be trained to instability or leak by rotating the visual surround with a velocity proportional to +/- horizontal eye position, respectively. Here we analyze changes in the firing rate behavior of neurons in area I in the caudal brainstem, a central component of the oculomotor neural integrator. Persistent firing could be detuned to instability and leak, respectively, along with fixation behavior. Prolonged training could reduce the time constant of persistent firing of some cells by more than an order of magnitude, to |1 s. Normal visual feedback gradually retuned persistent firing of integrator neurons toward stability, along with fixation behavior. In animals with unstable fixations, approximately half of the eye position-related cells had upward or unstable firing rate drift. In animals with leaky fixations, two-thirds of the eye position-related cells showed leaky firing drift. The remaining eye position-related

The oculomotor nerve is the third cranial nerve. It enters the orbit via the superior orbital fissure and innervates muscles that enable most movements of the eye and that raise the eyelid. The nerve also contains fibers that innervate the muscles that enable pupillary constriction and accommodation (ability to focus on near objects as in reading). The oculomotor nerve is derived from the basal plate of the embryonic midbrain. Cranial nerves IV and VI also participate in control of eye movement. The oculomotor nerve originates from the third nerve nucleus at the level of the superior colliculus in the midbrain. The third nerve nucleus is located ventral to the cerebral aqueduct, on the pre-aqueductal grey matter. The fibers from the two third nerve nuclei located laterally on either side of the cerebral aqueduct then pass through the red nucleus. From the red nucleus fibers then pass via the substantia nigra exiting through the interpeduncular fossa. On emerging from the brainstem, the nerve is ...
The Edinger-Westphal nucleus (accessory oculomotor nucleus) is the parasympathetic pre-ganglionic nucleus that innervates the iris sphincter muscle and the ciliary muscle. Alternatively, the Edinger-Westphal nucleus is a term often used to refer to the adjacent population of non-preganglionic neurons that do not project to the ciliary ganglion, but rather project to the spinal cord, dorsal raphe nucleus, and lateral septal nuclei.[1] Unlike the classical preganglionic Edinger-Westphal neurons that contain choline acetyltransferase, neurons of the non-preganglionic Edinger-Westphal nucleus contain various neuropeptides, such as Urocortin and cocaine- and amphetamine-regulated transcript.[2] Previously, it had been proposed to rename this group of non-preganglionic, neuropeptide-containing neurons to perioculomotor subgriseal neuronal stream, abbreviated pIIISG.[3] However, more recently, a final nomenclature has been determined. Preganglionic oculomotor neurons within the Edinger-Westphal nucleus ...

The oculomotor nerve is responsible for several parasympathetic functions related to the eye. The oculomotor PSN fibers originate in the Edinger-Westphal nucleus in the CNS and travel through the superior orbital fissure to synapse in the ciliary ganglion located just behind the orbit (eye). From the ciliary ganglion, the postganglionic PSN fibers leave via short ciliary nerve fibers, a continuation of the nasociliary nerve (a branch of ophthalmic division of the trigeminal nerve, CN V1). The short ciliary nerves innervate the orbit to control the ciliary muscle (responsible for accommodation) and the sphincter pupillae muscle, which is responsible for miosis or constriction of the pupil (in response to light or accommodation) (Netter and Hansen 2003).. The parasympathetic aspect of the facial nerve controls secretion of the sublingual and submandibular salivary glands, the lacrimal gland, and the glands associated with the nasal cavity. The preganglionic fibers originate within the CNS in the ...

Purpose: Innervation of the superior oblique muscle is separated into minimally overlapping lateral and medial compartments in primates, and superior and inferior compartments in non-primate mammalian species. The horizontal rectus muscles are divided into superior and inferior zones innervating non-overlapping sets of muscle fibers. We explored the innervation pattern of the IO muscle and determined the possibility of a compartmentalized model.. Methods: Whole orbits were obtained from two adult humans and three rhesus monkeys. Each orbit was formalin fixed, embedded in paraffin, coronally sectioned at 10 μm thickness, and stained with Masson trichrome. In digital micrographs, oculomotor nerve (CN3) branches were traced in serial sections using Photoshop and reconstructed using ImageJ to create 3-D overlays of CN3 innervation in the IO muscle fibers.. Results: CN3 travels from the deep orbit and innervates at the muscle belly of the IO. In both humans and monkeys, CN3 bifurcated into two major ...

Brain MRI (figure, A-E) revealed thickening of the right optic and third nerves. Fundus examination (figure, F) found Roth spots, which are highly suggestive of retinal leukemic infiltration.1 Lumbar puncture revealed blast cells. Other possible differentials were excluded. The right-side headache was probably due to ischemic changes of the nerves secondary to the leukemic infiltration. ...

Uncal herniation is a typical type of transtentorial herniation in which uncus, which is the innermost part of the temporal lobe of brain, heads for the tentorium and eventually puts pressure on the midbrain (upper brainstem) and the oculomotor nerve. Several clinical complications may arise from this condition relating to the eye and possibly brain damage. Uncal herniation is a medical emergency and should be dealt with immediately since delaying the treatment can cause permanent damage, and possibly death.. ...
Accommodation: The initial stimulus for accommodation is a blurred visual image that first reaches the visual cortex. Through a series of cortical connections, the blurred image reaches two specialized motor centres. One of these, located in the frontal cortex, sends motor commands to neurons in the oculomotor nucleus controlling the…
We recently examined a patient who developed a nearly complete unilateral third cranial nerve palsy attributed to sphenoid sinus aspergillosis. The unusual feature is that the palsy resolved spontaneously within 2 days.. A 78-year-old retired teacher presented with the sudden onset of a ptotic right upper lid and diplopia for 1 day. There was no headache. He had hypertension and chronic renal impairment but no diabetes or head trauma.. Vital signs were normal. Visual acuity was 20/40 in both eyes attributed to cataract. Intraocular pressures were 12 mm Hg in both eyes. In dim light, pupils measured 4.5 mm in the right eye and 3 mm in the left eye. The right pupil was not reactive to light; the left pupil was normally reactive. There was no afferent pupil defect. There was complete right upper lid ptosis and a complete deficit of adduction, supraduction, and infraduction of the right eye with normal incyclotorsion and abduction. Ductions of the left eye were normal. Findings from ophthalmoscopy ...
Paralysis of the third cranial nerve affects the medial, superior, and inferior recti, and inferior oblique muscles.. The eye is incapable of movement upwards, downwards or inwards, and at rest the eye looks laterally and downwards owing to the overriding influence of the lateral rectus and superior oblique muscles respectively. The reduced response of levator palpebrae superioris results in ptosis - a drooping of the upper eyelid.. A third nerve palsy with pupillary sparing is often termed a medical third palsy and often has an ischaemic or diabetic aetiology.. Full assessment of oculomotor nerve function involves testing of movement, reaction to light, and accommodation. If all of these are normal, PERLA may be written in the notes - pupils equal, reactive to light and normal accommodation. ...
Aberrant regeneration (reinnervation) is a misdirection of axons that occurs in the process of repair following conditions that cause mechanical disruption of a nerve. Axons that originally innervated one muscle are mistakenly routed to a different muscle. Following a command to the original muscle to contract, the aberrantly reinnervated muscle contracts in addition to, or instead of, the agonist. In aberrant regeneration of CN III, fibers originally destined to innervate the medial rectus may reinnervate the levator palpebrae or other extraocular muscles.(1,2) The lid elevates on adduction because of synkinesis between the medial rectus and the levator. Attempted upgaze may cause adduction because of misdirection of superior rectus fibers into the medial rectus. The upper lid may elevate on downgaze due to inferior rectus fibers aberrantly innervating the levator.

Recurrent painful ophthalmologic neuropathy (RPON), previously termed ophthalmoplegic migraine, is characterised by repeated attacks of one or more ocular cranial nerve palsies with ipsilateral headache. Its cause remains unclear; it is currently thought to be neuropathic in origin, but there is debate in the literature. In documented cases, a third cranial nerve palsy is by far the most common. Here we present a case of RPON involveing the fourth and sixth cranial nervesonly. Thorough investigation, including MR scan of brain and lumbar puncture, found no alternative explanation. This case adds to the debate over whether the cause of RPON is truly neuropathic or migrainous. ...

It is still unclear which neurotransmitters are being used by BIN neurons, how these neurons are connected to the rest of the brain and what their activity patterns look like. Here, we studied BIN neurons in a range of mammals, including macaque, human, rat, mouse, rabbit and ferret, using tracing, immunohistological and electrophysiological approaches. We show that BIN neurons are GABAergic and glycinergic, that in primates they also ...

A 9-year-old girl arrived at Schneider Childrens Emergency Medicine Department (ER) recently after her mother noticed a difference in the size of her pupils in both her eyes. Dr. Asaf Gershoni, an ophthalmologist in the ER, discerned that in addition to the dissimilar pupils, she also displayed limited eye movement as well as a fallen eyelid, concluding that the condition resulted from partial paralysis of the third cranial nerve.. The 3rd cranial nerve serves most of the eye and eyelid muscles, and the muscle of the iris at the rear which contracts the pupil. Paralysis of this nerve, especially when the pupil is involved, is a medical emergency because one of the possible causes could be an aneurysm in one of the brains arteries pressing along the path of the nerve at the base of the skull.. An emergency angiogram (CT scan of the brains vessels) confirmed the diagnosis of a brain aneurysm, a very rare occurance in children and life-threatening. If not treated immediately, it could lead to ...

Decision-making is a hallmark of higher-order cognitive processing. The neural substrates of decision-making have been studied extensively in the monkey oculomotor system. It has been found that neurons in the oculomotor system modulate their activity by the variable on which animals base their decision, and also appear to encode the dynamics of the decision process. An outstanding question raised by this work is whether the decision-related findings in the oculomotor system generalize to other systems beyond the oculomotor system. This question is of critical importance to decision sciences as decision-related neural signals serve to construct and constraint models of choice behavior. However, the work on the neural basis of decision-making in the monkey oculomotor system cannot address this question because in this literature animals make choices using eye movements. In these tasks, the decision-related neuronal modulation could therefore specifically reflect the decision to make an eye movement, and

Transcriptome analyses were performed in the anterior raphe area of mutant mice deficient in the serotonin transporter (5-HTT KO) or overexpressing this protein (5-HTT TG), which exhibit opposite changes in anxiety-related behavior. Among genes with altered expression, the gene encoding the neuropeptide urocortin 1 was down-regulated in 5-HTT KO and up-regulated in 5-HTT TG mice. Expression of the gene encoding cocaine-and-amphetamine-related-peptide, which colocalizes with urocortin 1, was also increased in 5-HTT TG mutants. Real-time RT-PCR confirmed these data and immunoautoradiographic labeling showed that parallel changes in neuropeptide levels were confined to the non-preganglionic Edinger-Westphal nucleus. Thus, 5-HTT expression correlates with that of urocortin 1, suggesting that this peptide can be involved in the behavioral changes observed in 5-HTT mutant mice.
