Using retrograde transport of the fluorescent dye Evans Blue (EB), in combination with glyoxylic acid histofluorescence, the ponto-spinal catecholaminergic pathways were investigated. The cells which contain catecholamine and project to the lumbar spinal cord of the cat are most densely concentrated in the Kölliker-Fuse nucleus. Locus coeruleus, the subcoeruleus area, and the parabrachial nucle...

Background: Signal to noise ratio (SNR) is defined as the of amplitude signal received by coil noise. Methods: This research was quantitative alongside an observational approach conducted at Radiology Installation Satya Negara Hospital, North Jakarta. Alongside a population Lumbar MRI patients with HNP clinical indication from October November 2022. The sample ten aged around 25-50 years diagno...

The spinal cord extends from the base of the skull and terminates near the lower margin of the L1 vertebral body. Below L1, the spinal canal contains the lumbar, sacral and coccygeal spinal nerves that comprise the cauda equina. Therefore, injuries below L1 involve the segmental spinal nerves and/or cauda equina. Injuries above the termination of the spinal cord at L1 often involve both spinal ...

Spinal cord and spinal dural blood flow in the cervical, thoracic and lumbosacral regions were measured in dogs using the radioactive microsphere technique. Measurements were taken before and 20 and 40 minutes after lumbar subarachnoid injection of one of the following: physiologic saline; tetracaine 20 mg or tetracaine 20 mg with epinephrine 200 micrograms. No significant change in spinal cord...

Introduction: Postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. Despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. Methods: Two groups, each of 10 New Zealand white male rabbits, were studied. Control g...

Although the mammalian locomotor CPG has been localized to the lumbar spinal cord, the functional-anatomical organization of flexor and extensor interneurons has not been characterized. Here, we tested the hypothesis that flexor and extensor interneuronal networks for walking are physically segregated in the lumbar spinal cord. For this purpose, we performed optical recordings and lesion experi...

BACKGROUND Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal f...

  Clear cell variant of ependymoma is almost exclusively located in the supratentorial region. Only few cases of this tumor that located in the spinal cord have been reported. Here we report one case of intramedullary clear cell ependymoma of the lumbar spinal cord. In microscopic examination, the tumor cells were round to oval with moderate amounts of clear cytoplasm and centrally located lar...

Non-patterned electrical stimulation of the posterior structures of the lumbar spinal cord in subjects with complete, long-standing spinal cord injury, can induce patterned, locomotor-like activity. We show that epidural spinal cord stimulation can elicit step-like EMG activity and locomotor synergies in paraplegic subjects. An electrical train of stimuli applied over the second lumbar segment ...

Recent results have demonstrated complete anatomical and functional repair of descending brainstem-spinal projections in chicken embryos that underwent thoracic spinal cord transection prior to embryonic day 13 (E13) of the 21 d developmental period. To determine to what extent axonal regeneration was contributing to this repair process, we conducted experiments using a double retrograde tract-...
