The H-reflex is produced when action potentials traveling proximally along sensory fibers enter the dorsal horn
of the spinal cord, stimulating the monosynaptic reflex arc.
Nociceptor signals, following acute injury, undergo complex processing in the dorsal horn
of the spinal cord (as explained by Melzack and Wall's gate control theory (12)).
The bombardment of neurons in the dorsal horn
by the primary afferent system stimulates N-methyl-D-aspartate receptors and overwhelms pain control centers (40).
2+]-dependent kinases to initiate the MAPK signaling cascade in the spinal dorsal horn
neurons (Wang et al.
1] cannabinoid receptors found on pre-synaptic cell membranes in the dorsal horn
of the spinal cord, hypothalamus, and peri-aqueductal gray matter (Mackie 2008).
After removing the receptor protein from the dorsal horn
, the itch was stopped and there was no impact on any other sensory sensations, such as pain, touch and temperature, meaning they had found the biocircut that causes itchy feelings.
Gamma-aminobutyric-immunoreactive neurons in the cerebral ganglion were detected in the medial edge of the cortex of the dorsal horn
of the ganglion in both sexes (Fig.
It features increased excitation at the level of the dorsal horn
nuclei and inhibition of descending pathways responsible for diffuse noxious inhibitory control.
After the nerve is damaged, it degrades and rebuilds itself at the site of the injury, but remodeling also occurs, possibly over a longer period, at the terminus of the nerve where it connects to dorsal horn
neurons," Patti said.
Fink and his colleagues are in the process of constructing a human-grade glutamic acid decarboxylase-expressing vector that will release gamma-aminobutyric acid into the dorsal horn
of Florence, Italy) explains in her introduction, the 22 chapters of this book "have evolved around the concept that the first sensory synapse between the central terminals of primary sensory neurons and dorsal horn
neurons in the spinal cord is plastic and modifiable" by neuronal and non-neuronal regulators, promising the identification of new targets for the treatment of chronic pain.
This sensitisation decreases the response of wide-dynamic-range neurons in the superficial dorsal horn
and high-threshold cells in the superficial or deep layers to mechanical stimulation by intradermal nociceptive stimuli (21).
In a article published in Science, Falk Eippert and colleagues from the University Medical Centre, Hamburg, found those who believed they had received pain relief experienced a dampening of the pain signalling in a region of the spinal cord, the dorsal horn
Increased ROS in dorsal horn
neurons may contribute to central sensitization in neuropathic rats (7).
These nerves are wired to the dorsal horn
of the spinal cord, which grabs the message and sends it on to the brain.
