Both visceral afferents from the gut and somatic nerves have cell bodies in the dorsal root ganglia and enter the dorsal horn
of the spinal cord .
34) The H-reflex is produced when action potentials that travel proximally along sensory fibers enter the dorsal horn
of the spinal cord and stimulate the monosynaptic reflex arc (Fig.
We have recently shown that neonatal hypersensitivity to touch is due to the late maturation of glycinergic inhibitory signalling and that this signalling, in turn, requires nociceptive activity in the dorsal horn
at a critical postnatal period.
Nociceptor stimulation triggers action potentials in sensory nerve fibres that transmit impulses to the dorsal horn
of the spinal cord.
Distinct antinociceptive actions mediated by different opioid receptors in the region of lamina I and laminae III-V of the dorsal horn
of the rat.
Correlation between spinal neuron counts and axial muscle histologic changes in 15 SBV-infected newborn calves, Belgium, January-March 2012 * Structure examined Control WBD/calf ID calves WBD-0 WBD-1 A B C D E F Axial muscles, histology Musculus semispinalis 0 NT 0 0 0 3 0 capitis, cas Musculus semispinalis 0 NT 1 0 0 2 0 capitis, ces Spinal cord Dorsal horn
The response properties of the dorsal horn
and brain stem neurons change due to continuous nociceptive input (12), altering the normal processing of nociceptive and non-nociceptive information.
Intraperitoneal administration of OMT decreased the mean IOD of NR2B in the dorsal horn
and expression of NR2B, p-ERK and p-CREB protein.
This analgesic effect is mediated by cannabinoid receptors within several nervous system areas: peri-aqueductal gray matter, medulla, thalamus, and the dorsal horn
of the spinal cord.
The team then looked at the dorsal horn
, the point in the spine where sensory signals are sent to the brain, to find cells that allowed the Nppb molecule to be received.
They are present in the insula, amygdala, hypothalamus, hippocampus, rostral ventromedial medulla and spinal dorsal horn
The cells were distributed mainly in the dorsal horn
