In vertebrates, sensory neurons interconnect a variety of peripheral tissues and central targets, conveying sensory information from different types of sensory receptors to appropriate second-order neurons in the central nervous system (CNS). To explore the possibility that the different rhombomere environments where sensory neurons enter into the hindbrain affect the pathfinding capability of ...

Anti-myelin oligodendrocyte (MOG)-positive cases have a variable clinical presentation. MOG autoantibodies are associated with acute disseminated encephalomyelitis, multiple sclerosis, clinically isolated syndrome, neuromyelitis optica, optic neuritis, and transverse myelitis. Our patient had bilateral neuritis tetraparesis. Cranial magnetic resonance imaging (MRI) showed leptomeningeal contras...

The relation between age at dystonia onset and sex was investigated in 264 patients with cranial-cervical dystonia and 56 patients with upper limb dystonia. In cranial-cervical dystonia, women had a significantly greater age at the onset of dystonia than men. The association was independent of duration of disease and distance of referral, but it was no longer detectable after adjustment for edu...

Small breed dogs were visited for the evaluation of neurologic deficits. On neurologic examination, all dogs were showed hyperesthesia, pain, neck stiffness or ataxia. After diagnosis by magnetic resonance imaging (MRI) dogs had cranial cervical decompression with durotomy. These dogs had the durotomy patched with autologous subcutaneous fat. The clinical signs of all dogs improved postoperativ...

Patients with small fibre neuropathy typically manifest pain in distal extremities and severe autonomic dysfunction. However, occasionally patients present with minimal autonomic symptoms. The basis for this phenotypic difference is not understood. Sodium channel Na(v)1.7, encoded by the SCN9A gene, is preferentially expressed in the peripheral nervous system within sensory dorsal root ganglion...

background: most research on autonomic dysfunction of diabetes mellitus is conducted on ganglions innervating gastrointestinal (gi) tract and there are limited works focusing on cervical sympathetic ganglia. the effects of diabetes mellitus (dm) on the neurons of superior cervical sympathetic ganglion (scsg) are investigated by stereological methods.   material and methods: female rats (n=72) r...

Cranial nerves govern sensory and motor information exchange between the brain and tissues of the head and neck. The cranial nerves are derived from two specialized populations of cells, cranial neural crest cells and ectodermal placode cells. Defects in either cell type can result in cranial nerve developmental defects. Although several signaling pathways are known to regulate cranial nerve fo...

Dendritic arborizations of neurons in the adult rat superior cervical ganglion were measured in control ganglia and in ganglia innervating peripheral targets that were relatively larger or smaller than normal. The relative size of the target--the submandibular gland in these experiments--was manipulated during development by changing the ratio between the amount of target tissue and the number ...
