Noxious mechanical heterotopic stimulation induces inhibition of the spinal dorsal horn neuronal network: analysis of spinal somatosensory-evoked potentials.

Most of the endogenous pain modulation (EPM) involves the spinal dorsal horn (SDH). EPM including diffuse noxious inhibitory controls have been extensively described in oligoneuronal electrophysiological recordings but less attention had been paid to responses of the SDH neuronal population to heter

Extracellular adenosine 5'-triphosphate (ATP) activates cell surface P2X and P2Y receptors. P2X receptors are membrane ion channels preferably permeable to sodium, potassium and calcium that open within milliseconds of the binding of ATP. In molecular architecture, they form a unique structural fami

BACKGROUND: Sensory nerves innervating the airways play an important role in regulating various cardiopulmonary functions, maintaining homeostasis under healthy conditions and contributing to pathophysiology in disease states. Hypo-osmotic solutions elicit sensory reflexes, including cough, and are

Zinc modulates primary afferent fiber-evoked responses of ventral roots in neonatal rat spinal cord in vitro

Otsuguro K.,Ohta T.,Ito S.
Neuroscience 138(1), 281-291, 2006
… Zn2+ enhanced the substance P-evoked depolarization in the absence of tetrodotoxin (0.3μM) but not in its presence. … It is concluded that Zn2+ potentiated slow ventral root potential induced by primary afferent stimulation, which was mediated by the activation of N-methyl-d-aspartate receptors but not by activation of P2X receptors or blockade of glycinergic and GABAergic inhibition. …

Medullary reticulospinal tract mediating the generalized motor inhibition in cats: Parallel inhibitory mechanisms acting on motoneurons and on interneuronal transmission in reflex pathways

高草木薫,Kohyama J,Matsuyama K,Mori S
Neuroscience 103(2), 511-527, 2001-03
… Conditioning medullary stimulation, which was subthreshold to evoke inhibitory postsynaptic potentials in the motoneurons, neither evoked primary afferent depolarization of dorsal roots nor reduced the input resistance of the motoneurons. … In contrast, it attenuated test postsynaptic potentials evoked through reciprocal Ia inhibitory pathways, and excitatory and inhibitory pathways from flexor reflex afferent and recurrent inhibitory pathways. …
