Chronic pain will help to manage light

Thanks to modern technology, scientists from McGill University were able to rid mice from acute pain. The opening was on the surface. It was enough to apply the available methods together with conventional light. Researchers believe that the developed method is to replace the narcotic analgesics to treat severe pain, e.g. in cancer patients. Yet such drugs are addictive and require a permanent increase in dosage. This effect does not cause optogenetics, says UPI.com.

For the experiment, scientists bred mice with the nerves that respond to light. The presence of the light source reduced pain from high temperatures.

The brighter was the light, the more pronounced effect was noted. Scientists now plan to create are harmless to humans virus that would turn the nerve endings, making them sensitive to light. About start such experiments with human participants is not reported. Apparently, they will happen not soon.
