How do spinal circuits mediating tactile sensation and pain get entangled to evoke allodynia, i.e., pain sensation, in response to a normally innocuous stimulus? Recent breakthroughs are now closing this long-standing, critical gap. VGLUT3-expressing neurons and their polysynaptic connectivity to calretinin-expressing neurons are now identified as key determinants of the spinal circuitry underlying mechanical allodynia.
