Scientists block sensitivity to cold in mice

So far they’ve been able to do it only in mice, but scientists at the University of Southern California have found a way to shut off the body’s ability to feel cold. The study, published in the Journal of Neuroscience identified the specific sensory neurons in the skin that communicate to the brain that the body feels a chill.

When these neurons were selectively shut off in mice, the mice no longer felt cold, but did maintain their ability to respond to heat and their overall sensitivity to touch.

Researchers explained that understanding the ways the body feels specific sensations, such as cold and heat, will help them develop better pain treatments without destroying a patient's ability to feel any sensations.
