Sign in In subject area:Veterinary Science and Veterinary Medicine The rubrospinal tract is a lateral brainstem motor pathway that can control distal limb musculature associated with skilled movement. From:Cunningham's Textbook of Veterinary Physiology (Sixth Edition),2020 ...
A spinal cord injury (SCI) is damage to the tight bundle of cells and nerves that sends and receives signals from the brain to and from the rest of the body. The spinal cord extends from the lower part of the brain down through the lower back. An SCI can occur anywhere along the spi...
After the injection of 3 μl toluidine blue into the L5 spinal nerve, the dye appeared in the L5 DRG and the L5 spinal nerve on the ipsilateral side, without extension into the contralateral DRG or other spinal nerves (Fig. 1A) compared to the intrathecal (Fig. 1B) and intra-DRG ...
Our understanding of how abdominal organs (like the gut) communicate with the brain, via sensory nerves, has been limited by a lack of techniques to selectively activate or inhibit populations of spinal primary afferent neurons within dorsal root ganglia
It is difficult to test thetectospinal tractin isolation due to the mixture of auditory and visual information it processes, but can include examination of those pathways from the respective cranial nerves influencing them, i.e. optic, oculomotor, trochlear, abducent andvestibulocochlear nerves, as ...
Sympathetic nerves are shown as thin continuous lines and hormones as interrupted lines. Pre- and post-ganglionic sympathetic nerves are shown bilaterally with arrows indicating enhancement of function, and blunted lines as inhibition. F = frontal lobe, P = parietal lobe, PPC = posterior parietal ...
In rats under isoflurane (4%) anesthesia, the left L5 spinal nerve was isolated adjacent to the vertebral column and tightly ligated with 6–0 silk sutures distal to the dorsal root ganglion and proximal to the formation of the sciatic nerve. In sham-operated rats, the L5 spinal nerves were...

It was hypothesized that input to the dorsal horn of the spinal cord could be manipulated to “close the gate” to the nerves. As an application of the gate control theory, Shealy et al. implanted the first spinal cord stimulator device directly on the dorsal column for the treatment of ...
