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 ...

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.

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 ...

N2 - Background: The purpose of this study was to consider the mechanism of isolated oculomotor nerve palsy after minor head trauma. Case Description: We report a rare case of delayed and isolated oculomotor nerve palsy following minor head trauma. A 19-year-old boy complained of double vision 1 day after a minor head trauma. Neuro-ophthalmic examination showed isolated left oculomotor nerve palsy. Computed tomography and magnetic resonance imaging examination revealed no abnormal findings and steroid therapy was administered for a week. Three months after the injury, the ptosis and extraocular movements had fully resolved, although the pupillary light reflex was still abnormal. Conclusions: Delayed and isolated oculomotor nerve palsy may be caused by an injury at the point where the oculomotor nerve ...

A 34-year-old man with a history of acute lymphoblastic leukemia (ALL) under consolidation treatment presented right-side blurred vision and headache associated with complete third right cranial nerve palsy. 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.. ...

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.
