How does the nervous system code, transmit, and process the information that steers our behaviour? Ronald S. Johansson’s research team at Umeå University in Sweden is now publishing its discovery of a new principle for this.
The prevailing view is that information is coded and transmitted by variations in the number of nerve impulses per time unit in the fibres of the nerve cells, that is, as a frequency code.
Johansson’s research team at the Section for Physiology present in the journal Nature Neuroscience a new principle for how information is coded and transmitted in the nervous system. When we manipulate objects, the brain reacts more quickly to the form of the objects and the direction of the contact forces than would be possible with frequency coding of information from the sensory organs of the fingertips. Frequency coding would require that the individual nerve fibre would have time to signal at least two impulses, and to interpret the message the brain needs to monitor signal traffic for a considerable period of time.

Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.
The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...
For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
