We've finally identified the nerve cells in the clitoris and penis that respond to vibration

Sagittal sections of mouse clitoris (left) and mouse penis (right) stained for S100 (magenta) and tdtomato (green) showing higher density of Krause corpuscles in the clitoris. S100 is a marker for terminal Schwann cells that wrap around the nerve terminals, while tdtomato labels the sensory nerve that innervates the Krause corpuscles.

Scientists have pinpointed the nerve cells that respond to vibration and light touch in the clitoris and penis — at least in mice. 

The new study also found that the ability of these neurons to respond to both light touch and vibration may be key to normal sexual function.
