New research: teaching the brain to reduce pain

10.07.2014

People can be conditioned to feel less pain when they hear a neutral sound, new research from the University of Luxembourg has found. This lends weight to the idea that we can learn to use mind-over-matter to beat pain. The scientific article was published recently in the online journal “PLOS One”.

Scientists have known for many years that on-going pain in one part of the body is reduced when a new pain is inflicted to another part of the body. This pain blocking is a physiological reaction by the nervous system to help the body deal with a potentially more relevant novel threat.

To explore this “pain inhibits pain” phenomenon, painful electric pulses were first administered to a subject’s foot (first pain) and the resulting pain intensity was then measured.

Then the subject was asked to put their hand in a bucket of ice water (novel stimulus causing pain reduction), and as they did so, a telephone ringtone sounded in headphones. After this procedure had been repeated several times, it was observed that the pain felt from the electrical stimulation was reduced simply when the ring tone sounded.

The brain had been conditioned to the ringtone being a signal to trigger the body’s physical pain blocking mechanism. The people being tested not only felt significantly less pain, but there were also fewer objective signs of pain, such as activity in the muscles used in the facial expression of pain (frowning). In total, 32 people were tested.

“We have shown that just as the physiological reaction of saliva secretion was provoked in Pavlov’s dogs by the ringing of a bell, an analogous effect occurs regarding the ability to mask pain in humans,” said Fernand Anton, Professor of Biological Psychology at the University of Luxembourg. “Conversely, similar learning effects may be involved in the enhancement and maintenance of pain in some patients,” added Raymonde Scheuren, lead researcher in this study.

Im Focus: Thousands on one chip: New Method to study Proteins

Since the completion of the human genome an important goal has been to elucidate the function of the now known proteins: a new molecular method enables the investigation of the function for thousands of proteins in parallel. Applying this new method, an international team of researchers with leading participation of the Technical University of Munich (TUM) was able to identify hundreds of previously unknown interactions among proteins.

Im Focus: 3-D printing produces cartilage from strands of bioink

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."

Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is...
