Pain is essential for survival. However, it could also slow rehabilitation, or could become a distinct disorder. How strongly we feel it depends on our individual pain threshold. Scientists have discovered that this threshold can be increased by a new fitness method called Jymmin. It combines working out on gym machines with free musical improvisation -- and makes us less sensitive towards physical discomfort.
Researchers have detailed, for the first time, the normal human transcriptome of the blood-nerve barrier. This barrier -- a tight covering of endothelial cells -- maintains the microenvironment of peripheral nerves. Knowledge of the transcriptome will aid research in peripheral nerve disease.
Several studies have shown an association between legalizing medical marijuana and lower death rates from opioids. A new study finds that link is more complex than previously described and appears to be changing as both medical marijuana laws and the opioid crisis evolve.
Two papers published today look at the current evidence of the effects of medical marijuana laws and conclude there is little support that such laws increase recreational marijuana use among adolescents or reduce opioid overdose deaths.
Neuroscientists have developed a method to measure brain activity during transcranial magnetic stimulation (TMS). TMS has been under investigation for 30 years, yet we still know very little about its mechanisms. A better understanding of TMS could contribute to the further development of this non-invasive, pain-free diagnostic and therapeutic tool.
Over-the-counter pain medicine such as Ibuprofen and acetaminophen may influence how people process information, experience hurt feelings, and react to emotionally evocative images, according to recent studies.
