In a new study recently published in Frontiers in Neurology, James, Carlstedt and other collaborators set out to understand how the implanted sensory root was connecting with the spinal cord in the dorsal horn.
These spikes transmit to lamina I secondary sensory neurons in dorsal horn, and finally to sensory cortex evoking a pain sensation.
SNI induced a robust astrocytic activation, indicated by GFAP upregulation in the ipsilateral spinal dorsal horn of SNI group (Fig.
The robust increase of JNK expression in JNK-IR cells was observed in the superficial region (laminae I–III) of the dorsal horn.
Interneuronal networks in the dorsal horn are responsible not only for the transmission of nociceptive information but also help modulate that information and pass it on to other spinal cord neurons, therefore, certain patterns of stimulation can lead to increase nociceptive transmission or inputs result in the inhibition of projection neurons.
As shown in figure 1, control rats showed a few c-Fos positive nuclei scattered throughout the dorsal horn without any clustering or apparent pattern, 2 hours after they received intrathecal saline.
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)).
In that study, whole-cell patch clamp recordings were performed from dorsal horn NK1 expressing neurons in an acute spinal cord slice preparation [12].
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 neurons, no.
Spinal cord stimulation attenuates augmented dorsal horn release of excitatory amino acids in mononeuropathy via a GABAergic mechanism.
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.
Next, transmission occurs when action potential is transmitted to the dorsal horn of the spinal cord (Pasero & McCaffery, 2011).
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.
