The neurons and mechanisms involved in mammalian spinal cord networks that produce rhythmic locomotor activity remain largely undefined. Hb9 interneurons, a small population of discretely localized interneurons in the mouse spinal cord, are conditionally bursting neurons. Here we applied potassium channel blockers with the aim of increasing neuronal excitability and observed that under these co...
The region surrounding the central canal (CC) of the spinal cord is a highly plastic area, defined as a postnatal neurogenic niche. Within this region are ependymal cells that can proliferate and differentiate to form new astrocytes and oligodendrocytes following injury and cerebrospinal fluid contacting cells (CSFcCs). The specific environmental conditions, including the modulation by neurotra...
Epoxyeicosatrienoic acids (EETs) are cytochrome P450-epoxygenase-derived metabolites of arachidonic acid that act as endogenous signaling molecules in multiple biological systems. Here we have investigated the specific contribution of 5,6-EET to transient receptor potential (TRP) channel activation in nociceptor neurons and its consequence for nociceptive processing. We found that, during capsa...
background & importance: acute autonomic system impairment can be dangerous and life-threatening, and a clinician should be aware of its occurrence possibility. according to the anatomy of this system, spinal cord lesions could disturb its function. there are many reports of autonomic dysreflexia in spinal cord i njuries especially spinal cord trauma. case presentation: a 28 year-old man with a...
Traumatic spinal cord injury is one of the important causes of disability.in some of vertebral fractures,spinal canal is deformed and compromised.the relationship between the shape of the cervical canal and spinal cord hnjury has been proved but such a correlation for thoraculombar spine 50 patients with compromised canal(cases) and 50 oatients with intact canal were evaluated in the light of s...
it has been shown that the immunophilin ligands have the special advantage in spinal cord repair. in this study, the effects of cyclosporine a (csa) on functional recovery and histological outcome were evaluated following spinal cord injury in rats. after spinal cord hemisection in thirty six adult female sprague-dawley rats (200- 250 g), treatment groups received csa (2.5 mg/kg i.p.) at 15min ...
The fluorescent probe FM1-43 has been used extensively for imaging vesicle recycling; however, high nonspecific adsorption resulting in elevated background levels has precluded its use in certain tissues, notably brain slices. We have found that a sulfobutylated derivative of beta-cyclodextrin (ADVASEP-7) has a higher affinity for FM1-43 than the plasma membrane. ADVASEP-7 was used as a carrier...

Neuronal networks generating rhythmic activity as an emergent property are common throughout the nervous system. Some are responsible for rhythmic behaviours, as is the case for the spinal cord locomotor networks; however, for others the function is more subtle and usually involves information processing and/or transfer. An example of the latter is sympathetic nerve activity, which is synchroni...
To ensure alternation of flexor and extensor muscles during locomotion, the spinal locomotor network provides rhythmic inhibition to motoneurons. The source of this inhibition in mammals is incompletely defined. We have identified a population of GABAergic interneurons located in medial laminae V/VI that express green fluorescent protein (GFP) in glutamic acid decarboxylase-65::GFP transgenic m...
