Children's holiday program for the second time at the Bernstein Center
06.12.2011: During this year's autumn school break, the BCF again hosted the holiday program of the University's family service. In the first week of November, the children of university employees made use of Freiburg’s Schlossberg as the lift-off place for self-made kites. The Bernstein Center, located at the foot of the hill, made an ideal base for this.

Divide and compute: Scientists find explanation for special wiring structure between two brain regions
28.11.2011: Although the cortex, the outer layer of our brain, is commonly seen as the seat of cognition, other areas are involved in thought processes and behaviour as well. Whenever we need to make a decision or select a course of action from several alternatives, communication between the cortex and a structure called the striatum plays a crucial role. The peculiar wiring between these regions has been known for some time, but a study by Man Yi Yim and colleagues from the Bernstein Center at the University of Freiburg for the first time provides an explanation how this kind of connection serves a specific purpose. Their work has been published in the latest issue of PLoS Computational Biology.

Crippling rhythms of the brain: Network model reveals new insights into causes and possible treatments of Parkinson’s disease
07.11.2011: Although Parkinson’s disease is one of the most common neurological disorders, its causes at the level of neuronal mechanisms are still poorly understood. Electrical stimulation has proven to alleviate many symptoms, but how exactly it achieves this, remains a mystery. Arvind Kumar and colleagues at the Bernstein Center Freiburg now provide a unified explanation of how Parkinson’s symptoms arise, how deep-brain stimulation (DBS) can counteract them, and how the method can be improved. Their study appears in the current issue of “Frontiers in Systems Neuroscience”.

Getting a grip on grasping: Scientists from Freiburg decipher brain commands for different grasp types
22.07.2011: Quickly grabbing a cup of coffee is an everyday action for most of us. For people with severe paralysis however, this task is unfeasible – yet not “unthinkable”. Because of this, interfaces between the brain and a computer can in principle detect these “thoughts” and transform them into steering commands. Scientists from Freiburg now have found a way to distinguish between different types of grasping on the basis of the accompanying brain activity.

In 2011, the three awardees are Jan Korvink (IMTEK), Bent Gebert (German Seminar) and Janina Kirsch, the Teaching & Training Coordinator of the Bernstein Center Freiburg.
How does network structure shape brain activity? : New article in PLoS Computational Biology relates correlations in the activity of nerve cells to the detailed structure of the underlying network
20.05.2011: Despite recent advances in our understanding of brain function, it is still largely unknown how activity in the brain’s cortex ultimately contributes to our mental abilities – to perceive, to remember, or to think. It is widely accepted, though, that neurons cannot achieve any of these functions in isolation. Rather, they have to partner up with others. As groups or larger populations of neurons orchestrate their activities, this is accompanied by a certain degree of temporal coordination between the involved signals. In data analysis this leads to so-called “correlations”.
Article by BCF members in PLoS Computational Biology on learning from dopamine signals

Thinking outside the column: BCF members publish in "Frontiers in Neuroscience", new insights into brain structure reveal new facets of information processing in the nervous system
28.04.2011: For more than 50 years, a dominating assumption in brain research was that nerve cells in the cortex of the brain are organised in the form of microscopically small columns. Subsequently, it became a textbook standard that connections are created predominantly between nerve cells within these columns. In a review article for the journal “Frontiers in Neuroscience”, Clemens Boucsein and Martin Nawrot – together with their colleagues from the Bernstein Centers in Freiburg and Berlin – show that this view has to be revised: Input from cells that lie outside this column plays a much more important role than hitherto assumed.
Masked fears: New article by BCF scientists in PLoS Computational Biology explains the origin of fear processes in the brain – and why it is so difficult to overcome them
18.03.2011: Fear is a natural part of our emotional life and acts as a necessary protection mechanism. However, fears sometimes grow beyond proportions and become difficult to shed. Scientists from Freiburg, Basel and Bordeaux have used computer simulations to understand the processes within the brain during the formation and extinction of fears. In the current issue of the scientific journal PLoS Computational Biology, Ioannis Vlachos from the Bernstein Center Freiburg and colleagues propose for the first time an explanation for how fears that were seemingly overcome are in reality only hidden.
How clear is our view of brain activity? : BCF researchers publish article in "Human Brain Mapping", demonstrating the large influence of filtering algorithms on results in brain imaging
17.03.2011: Imaging techniques have become an integral part of the neurosciences. Methods that enable us to look through the human skull and right into the active brain have become an important tool for research and medical diagnosis alike. However, the underlying data have to be processed in elaborate ways before a colourful image informs us about brain activity. Scientists from Freiburg and colleagues were now able to demonstrate how the use of different filters may influence the resulting images and lead to contradicting conclusions.
