Wie ist das große Gehirn entstanden?
Neue Erkenntnisse zur Entwicklung des menschlichen Gehirns Göttingen/Germany, 27. Maerz 2025. Zwei spezifische Gene, die ausschließlich beim Menschen vorkommen, beeinflussen gemeinsam die Entwicklung des Großhirns. Dies haben Forschende des Deutschen Primatenzentrums – Leibniz-Institut für Primatenforschung und des Max-Planck-Instituts für molekulare Zellbiologie und Genetik in einer jetzt veröffentlichten Studie herausgefunden. Damit ist ihnen der Nachweis gelungen,…

Less changes a lot Reduced dopamine production influences learning ability in a surprising way
New findings on dopamine and learning. Researchers at the Leibniz Institute of Neurobiology (LIN) have shown in a recently published study that a reduction in dopamine production in the brain alters learning in a surprising way. Their study showed that a reduced dopamine level improves the association of stimuli with punishment at unusually long time…

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…

Sleep keeps memories fresh Neural patterns reorganize during sleep to boost recollection
Why is sleep so important for learning and memory? Neuroscientists from the Csicsvari group at the Institute of Science and Technology Austria (ISTA) provided new insight into this essential function by monitoring neuronal activity in rat brains for up to 20 hours of sleep following spatial learning. Central to the findings are reorganizations of neuronal…

The brain moves when we do. DFG funds cooperation on place cells and spatial learning
Researchers from Magdeburg and Erlangen are jointly investigating how our brain learns to orientate itself in spaces and store memories. At the Leibniz Institute of Neurobiology (LIN), scientists are analysing how neurons in the hippocampus control our spatial learning. To do this, they record in fast motion what happens in the brains of mice while…

Two brain areas in competition
Researchers at Ruhr-Universität Bochum have investigated how two areas of the brain influence the nature of memory content. The team from the Department of Neurophysiology showed in rats how the locus coeruleus and the ventral tegmental area permanently change brain activity in the hippocampus region, which is crucial for memory. The influences of the two…
