Researchers at Lund University in Sweden have developed a new stimulation method that uses ultra-thin microelectrodes to combat severe pain
The lack of treatment for long-term pain without side effects often greatly impairs the quality of life of patients
Pain can also bring considerable costs to society in the form of sick leave, health care costs and production losses
In Lund, a research team led by professor of neurophysiology Jens Schouenborg has developed a method to combat pain through personalized stimulation with ultra-thin, tissue-friendly microelectrodes
"The electrodes are very soft and gentle on the brain
Pain is blocked by activating the pain control centers of the brain, and these centers in turn only block the transmission of pain signals to the cerebral cortex
"We have almost achieved a complete blockade of pain without affecting any other sensory systems or motor skills.
In this project, which has been running for several years, researchers have developed a tissue-friendly gelatin-based technique and surgical technique that makes it possible to implant flexible microelectrodes with very high precision
The most common painkillers today are through the use of drugs
"In our study, we also compared our method with morphine, which has a much smaller analgesic effect
Lund’s research was conducted on rats
"This is our goal
Researchers hope that within 5 to 8 years, this method will lead to satisfactory stimulation treatments for particularly severe pain, such as cancer pain or chronic pain associated with spinal cord injury.
Researchers also believe that in addition to pain, this method can also be used for a wider range of treatments
"In principle, this method can be applied to all parts of the brain, so we believe it can also be used to treat degenerative brain diseases, such as Parkinson's disease, as well as depression, epilepsy and possible stroke
