现在，明尼苏达大学的一项研究表明，抓挠能够抑制脊髓神经的活动，正是脊髓神经向大脑传递痒的感觉。研究者希望最终能弄清这种抑制是如何工作的。

Giesler theorizes that the itch sensation creates an excited state in the STT neurons that scratching inhibits - as if our fingernails were sending a message to spinal-cord neurons to cool off.

Giesler提出一种理论认为，瘙痒感在STT神经元里面产生一种兴奋的状态，而搔痒可以抑制这种状态——好像是我们的手指给脊髓神经元发指令让它们冷静下来。
