How the brain brings back memories of past events remains largely unknown. In a collaboration between the MRC Cognition & Brain Sciences Unit in Cambridge (Dr. Maria Wimber), the University of Konstanz (Dr. Simon Hanslmayr, Zukunfskolleg) and the Otto-von-Guericke University Magdeburg, researchers have now identified a rapid memory reactivation mechanism that has so far only been speculated about. In this project, participants learned long lists of words while the screen was flickering at different frequencies. Such flickering stimulation is known to induce a frequency-specific "oscillating" brain signal that is clearly visible in the human electroencephalogram (EEG). The study revealed that when participants later remember one of the previously studied words, the brain rapidly reproduces a signal at the particular frequency that had been present during learning. These results indicate that when people recollect past events, the brain transiently returns to the state that it was in when the event had first been encountered. The study is available online in Current Biology:
Simon Hanslmayr, Research Fellow of the Zukunftskolleg, published an article concerning successful memory formation in the renowed journal “The Journal of Neuroscience”. Using simultaneous EEG–fMRI recordings in humans during long-term memory encoding it was possible to demonstrate which neuronal synchronisation pattern underlie the formation of new memory effects. The complete article “The Relationship between Brain Oscillations and BOLD Signal during Memory Formation: A Combined EEG–fMRI Study” can be found here.
Together with organic chemists of the University of Konstanz the working group of the Zukunftskolleg Fellow Malte Drescher developed an innovative research method for studying bonding mechanisms between multivalent carbohydrates and proteins. The results of this research are published as a cover article in the journal “Angewandte Chemie” and could be used in cancer research.
Further information is available in the (German) press release of the University of Konstanz.
