Ventrally Located Cervical Dumbbell Ganglioneuroma Producing Spinal Cord Compression
Ganglioneuroma is an uncommon benign tumor and arise from neural crest cells or sympathetic and peripheral nerves. A 13-year-old boy was referred to our institute and presented with three-day history of right upper extremity weakness associated with neck pain for nearly one month. Magnetic resonance imaging showed right side dumbbell shaped extramedullary lesion at the C2-3 level extending outs...
متن کاملActivity patterns and synaptic organization of ventrally located interneurons in the embryonic chick spinal cord.
To investigate the origin of spontaneous activity in developing spinal networks, we examined the activity patterns and synaptic organization of ventrally located lumbosacral interneurons, including those whose axons project into the ventrolateral funiculus (VLF), in embryonic day 9 (E9)-E12 chick embryos. During spontaneous episodes, rhythmic synaptic potentials were recorded from the VLF and f...
متن کاملA dorsally located giant posterior fossa neurenteric cyst in a Chinese woman.
Neurenteric cysts (NC) are rare, endodermal-derived intracranial lesions, commonly located anteriorly in the posterior cranial fossa. We describe a rare case of a giant posterior fossa NC (6.5 × 5.9 × 4.3cm) located dorsal to the brain stem in a Chinese woman with a 1 week history of cerebellar symptoms. To our knowledge, this is the largest documented cyst of this type and the third dorsally l...
متن کاملPatterns of synaptic drive to ventrally located spinal neurones in Rana temporaria embryos during rhythmic and non-rhythmic motor responses.
1. Intracellular recordings have been made from ventrally located neurones in the spinal cord of Rana temporaria embryos at around the time of hatching. Both short-latency 'reflex' and more prolonged rhythmic motor responses can be elicited by stimulation of the skin in immobilized embryos. Initial responses to single-sided skin stimuli usually involve excitation of neurones on the opposite sid...
متن کاملDorsally and ventrally derived oligodendrocytes have similar electrical properties but myelinate preferred tracts.
In the developing spinal cord, most oligodendrocyte precursors (OLPs) arise from the ventral ventricular zone (VZ) under the influence of Sonic Hedgehog, but a minority are generated from the dorsal VZ in a Hedgehog-independent manner. In the developing forebrain too, OLPs arise from both the ventral and the dorsal VZ. It is not known whether dorsally and ventrally derived oligodendrocyte (OL) ...
