Deciphering the sequence of neuronal firing
How does the brain retain a sequence of events in memory? Researchers from the University Hospital Bonn (UKB), the University of Bonn, the University Hospital Tübingen and the University of Tübingen investigated this question. Using a unique measurement technique with implanted electrodes in the human brain, they were able to test a widely accepted theory…

Novel memristors against the catastrophic forgetting of AI
They require extremely little power and behave similarly to brain cells: so-called memristors. Jülich researchers led by Ilia Valov have now presented novel memristive components in Nature Communications that have significant advantages over previous versions: They are more robust, function in a wider voltage range and can be operated both analogue and digitally. With these…

Why deep sleep promotes our memory Slow brain waves make the cerebral cortex particularly receptive
It has been known for almost 20 years that slow, synchronised excitation waves during deep sleep support memory formation. It was previously unknown why this is the case. A research team from Charité – Universitätsmedizin Berlin has now provided an explanation in the journal Nature Communications*. The slow waves make the cerebral cortex, the seat…

How is our memory wired Pattern completion process
The black box of the human brain is beginning to open. Although animal models are crucial to our understanding of the mammalian brain, the less frequently collected human data is revealing important features. In a paper published in Cell, a team led by the Jonas Group at the Institute of Science and Technology Austria (ISTA)…

Cooperation in society How our memory influences our behaviour
Co-operation often arises through ‘direct reciprocity’, where help is based on mutuality. A study shows that strategies that take into account several past moves of a fellow player promote co-operation. It is crucial to analyse the entire behaviour rather than just the frequency of cooperation. This emphasises the importance of a longer memory and complex…

Autobiographical memory in the digital age – our lives reflected in our data
Never before have people recorded more information about their lives than today. But what does this mean for the way we remember our lives and how we talk about them? A research team from the University of Würzburg and the Leibniz-Institut für Wissensmedien (IWM) in Tübingen is trying to find answers to these questions. Together…
