在中枢它作为神经递质发挥作用且与痛觉传导有关，在外周神经它作为诱导神经源炎症的物质发挥作用。
As a neuropeptide it plays role and conducts the senses of pain in the central nervous system, as well as inducts neurogenic inflammation in the peripheral nervous system.
这些神经元可以将痛觉、温度以及触觉传导至大脑。 （以前的研究表明，给予产生瘙痒的感觉像组胺之类的物质后可以激活STT，而且这些神经元可以将那些痒觉传导至大脑。）
Previous studies have shown that STT neurons can be activated with the application of an itch-producing chemical like histamine, and that the neurons send that itch sensation to the brain.
NGF似乎和痛觉信号的传导有关。
分析其可能的原因是传导痛觉的脊髓丘脑侧束在上行过程中有不交叉纤维。
The cause may be that there were uncrossing nerve fibers in the lateral spinothalamic tract.
SCN9A是一种基因的名称，一种蛋白质的代码。这种蛋白质让神经信号的传导通道长久地保持活性，结果是传递了更多的痛觉信号。
One gene, known as SCN9A, codes for a protein that allows the channels along which nerve signals are transmitted to remain active for longer and thus transmit more pain signals.
脊髓丘脑束神经细胞在传导痛觉中同样起主要作用，但疼痛时抓挠却不会止痛，其原因目前仍不知。
Scientists have shown scratching helps relieve an itch as it blocks activity in some spinal cord nerve cells that transmit the sensation to the brain.
脊髓丘脑束神经细胞在传导痛觉中同样起主要作用，但疼痛时抓挠却不会止痛，其原因目前仍不知。
Scientists have shown scratching helps relieve an itch as it blocks activity in some spinal cord nerve cells that transmit the sensation to the brain.
