NMDA受体的激活是启动和维持敏化的必要步骤(n-甲基-d -天冬氨酸是谷氨酸)受体。 Glutamate is a widespread excitatory neurotransmitter in the nervous system). * Under normal circumstances this receptor channel is blocked by Mg2+ ionsMayer ML, Westbroke GL, Guthrie, PB. Voltage-dependant block by Mg2+ of NMDA responses in spinal cord neurones. Nature 1984;309:261-263.. * Sustained release by nociceptors of glutamate, substance P and CGRP leads to membrane de-polarization, forcing the Mg2+ from the NMDA receptor. * This rapidly boosts synaptic efficacy and allows Ca2+ in to the neuron, activating intracellular pathways and maintaining central sensitisation.
