A confocal laser microscopic study of enkephalin-immunoreactive appositions onto physiologically identified neurons in the rostral ventromedial medulla.
Neurons in the rostral ventromedial medulla (RVM) are important in the opioid modulation of dorsal horn nociceptive transmission. Systemically administered morphine inhibits one class of RVM cells, the on-cells; excites a second class of RVM cells, the off-cells; and has no effect on a third class, neutral cells. In contrast, iontophoretic application of morphine inhibits on-cells but does not ...
متن کاملorexin-a modulates firing of rat rostral ventromedial medulla neurons: an in vitro study
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...

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولIdentification of cardiovascular neurons in the rostral ventromedial medulla in anesthetized rats.
Recent studies have identified a region in the rostral ventromedial medulla (RVMM) of rats that appears to be involved in cardiovascular function. Since these studies used either microinjection of lidocaine or electrical stimulation, the exact contribution of intrinsic neurons as opposed to fibers of passage could not be determined. The present study was performed to map the location of neurons...
