文摘
- •
C-LTMs (C-mechanoreceptors) are thought to exist only in the hairy skin.
- •
Direct evidence that C-LTMs exist in glabrous skin of rat hindpaw is provided.
- •
They constituted >6% of the C-fiber neurons with receptive fields in glabrous skin.
- •
Their mechanical and electrical thresholds are much lower than those of C-nociceptors.
- •
They have faster action potential kinetics than C-nociceptors.
