New insights into the energy balance of brain neurons
A research team at the Carl Ludwig Institute for Physiology at Leipzig University has,for the first time, demonstrated how the energy levels of individual neurons in the brain change during so-called spreading depolarizations – waves of activity that occur in various brain disorders. The findings provide important foundations for understanding energy metabolism in cases of…

Study The brain learns to filter out distracting stimuli over time
The human brain can learn through experience to filter out disturbing and distracting stimuli – such as a glaring roadside billboard or a flashing banner on the internet. Scientists at Leipzig University and Vrije Universiteit Amsterdam have used electroencephalography (EEG) to show that early visual processing in humans changes with repeated exposure. Their joint study…

How the brain controls movements in the face of uncertainty
A new study by neuroscientists at the German Primate Centre (DPZ) – Leibniz Institute for Primate Research in Göttingen shows that our brain deals with different forms of visual uncertainty during movements in different ways. Depending on which type of uncertainty is involved, this has very different effects on the planning and execution of movements…

What is the difference between the brains of men and women? The focus is on glial cells
Alzheimer’s disease predominantly affects women, while more men suffer from Parkinson’s disease. The reason for this presumably lies in differences in the brain that emerge early in embryonic development. So far, research has focussed on neurons. However, another cell type, glial cells, could also influence diseases in a gender-specific way. They are therefore the focus…

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…
