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…

How the brain evaluates rewards
Study shows how individual neurons process probability, magnitude and risk of rewards Gottingen/Germany, April 2, 2025. Researchers have gained a new understanding of how the brain processes reward and risk information. A study by neuroscientists Raymundo Báez-Mendoza from the German Primate Center (DPZ) – Leibniz Institute for Primate Research in Göttingen and Fabian Grabenhorst from…

Artificial neurons organize themselves
Novel artificial neurons learn independently and are more strongly modeled on their biological counterparts. A team of researchers from the Göttingen Campus Institute for Dynamics of Biological Networks (CIDBN) at the University of Göttingen and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) has programmed these infomorphic neurons and constructed artificial neural networks from…
