The skin on the tips of your fingers wet wince because of the involuntary reaction of the brain. The resulting surface is an analogue of the tread on a car tire.



Mark Changizi, an evolutionary neurobiologist lab 2AI in Boise (Idaho), came across a study of the 1930s, according to which the creases on the fingers thoroughly limp filaments do not form if the nerves in the fingers cut off. One of his subordinates Changizi with which professor was discussing the find, suggested that the "potholes" on a wet finger - similar pattern on the tires, the car provides a better grip.

According compulenta.ru, Changizi and his colleagues analyzed 28 large photos of wet wrinkled fingers belonging to different people, and concluded that the arrangement of folds everywhere and always identical: single channel diverge from the pads and do not intersect. The pressure exerted on the surface of the finger is attached to the main pad, and play the role of wrinkles guttering.

The scientific world accepted the idea in different ways: Biomechanics of Columbia University Xi Chen believes that the fingers shrivel simply because of narrowing of blood vessels in hot water. However, this does not explain why there are folds in the cold, and why wrinkles do not occur on the fingers with broken nerves, says neurosurgeon Jin-Hua Xie changun hospital in Kaohsiung (Taiwan).

Pilot tests have shown that the folds on the human fingers really wet grip improves.
