Introduction: In Iran, thousands of young individuals become victims of head injury annually. Head injury can damage neuronal cells which may in turn complicate the recovery of the patients. Also, the increase of iron in cerebrospinal fluid (CSF) following head injury may contribute to the hypoxic-ischemia brain damage by catalyzing the formation of free radicals (Harber-Weiss Rection). The obj...

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 ...

A full understanding of nervous system function requires recording from large populations of neurons during naturalistic behaviors. Here we enable paralyzed larval zebrafish to fictively navigate two-dimensional virtual environments while we record optically from many neurons with two-photon imaging. Electrical recordings from motor nerves in the tail are decoded into intended forward swims and...

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

the rostral ventromedial medulla (rvm) acts a key role in the descending inhibitory pain modulation. neuropeptide orexin-a (orxa) is confined to thousands of neurons in the lateral hypothalamus (lh). while rvm gets the orexinergic projections, the orexin receptors are also expressed in this structure. the aim of this study was to specify the cellular effects of orxa on rvm neurons in vitro by u...

Neuroethologists try to assign behavioral functions to certain brain centers, if possible down to individual neurons and to the expression of specific genes. This approach has been successfully applied for the control of circadian rhythmic behavior in the fruit fly Drosophila melanogaster. Several so-called "clock genes" are expressed in specific neurons in the lateral and dorsal brain where th...
