Scientists are working on the nature of pain, by the help of light researchers get pain relief and get more pain as well.The mice in Scott Delp's lab are making it possible for scientists study about pain and about more like without any injury why pain feel.
The researchers used a technique called optogenetics, which involves light sensitive proteins to put into the nerves called opsins.One light color causes the mice to feel more pain and other causes the reduction in pain. Delp's colleague Karl Deisseroth, MD, PhD, a co-author of the study was developed Optogenetics and the study published on Feb. 16 in Nature Biotechnology.
The researchers said that the new research allows to better understand different kinds of pain and gives a chance researchers to discover more in future on the nature of pain, touch and other feelings.
"The fact that we can give a mouse an injection and two weeks later shine a light on its paw to change the way it senses pain is very powerful," Shrivats Iyer said.
Scott Delp, who takes an interest in muscles and movement , whose lab made this discovery,was using optogenetics to control movement, pain, touch and other sensations suddenly he found that the opsins were also making the nerves to control pain."We thought, wow, we're getting pain neurons—that could be really important," Scott Delp said.
At the end, Scott Delp said, "Developing a new therapy from the ground up would be incredibly rewarding," he said. "Most people don't get to do that in their careers."
