The Glass Brain

26.03.2007
It is one of the great dreams of brain research to visualize at once all nerve cells and their connections of a complete brain in 3D. Scientists of the Max Planck Institute of Psychiatry in Munich and the Vienna University of Technology (TU Vienna) have now come a step closer to turning this dream into reality.

They have succeeded in making whole mouse brains transparent and then to reconstruct parts of their neuronal networks with a computer. During their investigations at the MPI of Psychiatry they put mouse brains in an oil solution which rendered the brains completely transparent, as now published in Nature Methods. They transilluminated these transparent brains with a laser from the side layer by layer. This way, green fluorescence was induced in genetically marked nerve cells.

Using the many images from their “ultramicroscope” the scientists in the research group of the medical doctor and physicist Hans-Ulrich Dodt were able to reconstruct parts of the neuronal network in three dimensions, comparable to computer tomography but with much higher resolution.

Prof. Dodt who was appointed to the chair of Bioelectronics of the TU Vienna in January, plans to utilize this method to investigate the complex neuronal networks of the cortex. The scientists are interested to see if it is possible to visualize alterations at nerve cells after learning using this method. Ultramicroscopy will also be used to investigate the development of neuronal diseases like Alzheimer`s in mice. Besides science, the technique also has an aesthetic aspect: One can simulate a fly-through the brain using the recorded data. Therefore in the future the technique of the glass brain will be used probably for teaching students employing a “Playstation Brain”.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
