Brain Activity

We all may know that imaging techniques have become an integral part of the neurosciences. 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. Tonio Ball of the Bernstein Center Freiburg and colleagues from the universities of ldenburg, Basel and Magdeburg demonstrate how variable the results of imaging techniques like functional Magnetic Resonance Imaging (fMRI) can be – depending on the way how the original data are filtered.
