For the traditional understanding of neuroscience, touch from the skin only in the most advanced part of the brain – the cerebral cortex assembled to form a complete experience. However, a new study from Lund University in Sweden found that subvert this awareness, this new study shows that other aspects of the brain play a larger role than previously thought, and the different structures of the brain involved in touch perception plays a larger proportion.

“It is believed that the touch, like the touch of a simple object, only the activation of the cerebral cortex of a very small part, but our findings suggest that this may be a larger part of the activation fact, the feeling is the beginning of the brainstem assembly, “neuroscience researcher at Lund University Henrik J? rntell said.

His colleague Frederick Bengtsson (also involved in the study) said that this is the first study to show that the complex tactile coding from the skin at the level of how the brain cells. He said: “Our new findings give us a key to understanding how the perception of touch skin treatment, and communicated to the brain.”

Researchers at Lund University in collaboration with researchers in Paris, studied how individual nerve cells receive information from the skin. They used a technique called “haptic interface” technology, to create the feeling of rolling and sliding control, and contacts to start and stop the action. Movement played a decisive role in the perception of touch – this is no technology in the study of the previous function.

The study was published in a recent “Neuron” magazine, this work is the first and basic research experiments on animals, its purpose is to increase the knowledge of brain function. However, it is also possible areas of application.

“Normal prosthetic arm there is no sense, there is no feeling of a ‘real’ hands or arms, however, there is now a new, advanced prostheses have sensors that can provide information to the amputation of arms, our study may contribute to the further development of this sensor, “Henrik J? rntell said.

The new findings may also be of mental illness and brain disorders such as stroke and impact of Parkinson’s disease. Detailed knowledge about the brain information processing and tactile experience and various parts of the picture drawn for understanding these situations is very important.

“If we know how a healthy brain works, we can compare the situation of different diseases, then we might be able to help patients become more normal brain function,” Henrik J? Rntell said.
