On September 4, 2023, Minister-President Michael Kretschmer and Max Planck President Patrick Cramer hosted a ceremonial event at the Kulturpalast in Dresden commemorating the 30-year success story of the Max Planck Society in Leipzig and Dresden.

When the human body is exposed to stress, it goes into the very same emergency mode that it used in the Stone Age. However, that reaction is not nearly as well suited to our way of life today. Scientists at the Max Planck Institute of Psychiatry and the Max Planck Institute for Human Cognitive and Brain Sciences are studying what happens in the body during stress, who is particularly susceptible to stress, as well as when it is an especially bad time to have to deal with a large amount of stress.

What holds matter together? What binds the universe? What is the nature of human thought? Charlotte Grosse Wiesmann of the Max Planck Institute for Human Cognitive and Brain Sciences has always been interested in the big questions. Grosse Wiesmann, who originally studied physics, now investigates which developments in the brain enable children to empathize with others.

Operatic singing. Birdsong. Loud shouting. An off-pitch violin. We instinctively find some sounds pleasant, others unpleasant. But how do we decide whether something sounds good or bad? And how is sound actually processed within the brain? In an attempt to answer these questions, a team led by David Poeppel at the Max Planck Institute for Empirical Aesthetics in Frankfurt is trying to break down speech and music into their most elementary components. And at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, researchers are investigating the secret of super-hits.

For us, it appears natural that children should start to speak at some point. Yet learning language is a major feat, which is still not fully understood even today. The Departments led by Caroline Rowland at the Max Planck Institute for Psycholinguistics in Nijmegen and Angela Friederici at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig are using a wide range of methods to investigate how children learn this complex system of communication with seemingly no effort.

Thomas Fritz, Leader of the Music Evoked Brain Plasticity Research Group at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, knows how to make people happy and fearless - essentially as a kind of welcome side-effect. He conducts experiments using exercise machines with which you can create music. The experience of exercising with this equipment and simultaneously creating unique sounds not only reduces bodily exhaustion, it also puts the user in a good mood and lowers their anxiety and pain levels - effects that give rise to a range of therapeutic applications.

From childhood, our active vocabulary grows to about 20,000 words, which we link together according to certain rules to form an infinite number of linguistic expressions. Since sentences are superficially just strings of words, similar to the sequence of motor actions, it has been argued that the processing of language and actions share a common cognitive lineage in the form of overlapping neural resources. Our work challenges this parallelism and instead demonstrates the independence of language and action processing. 

Mental training that promotes skills such as mindfulness, gratitude or compassion reduces the concentration of the stress hormone cortisol in hair. The amount of cortisol in hair provides information about how much a person is burdened by persistent stress. Earlier positive training effects had been shown in acutely stressful situations or on individual days – or were based on study participants’ self-reports. The current study thus provides the first objective evidence that mental training reduces physical signs of long periods of stress, even in healthy people.

Superficial white matter (SWM), a less than 1 mm thick interface between grey and white matter, contains most cortico-cortical white matter connections encompassing the short U-fibers. We developed an advanced neuroimaging method for SWM mapping in living individuals. Thereby we were able to show that the SWM contains significant amounts of iron. It is assumed that this iron is required for the myelination of the U-fibres. Our SWM mapping approach paves for systematic studies in the inter-individual differences, brain plasticity and pathologies in the human brain.

Humans are capable of transcending beyond the here and now. Our memory systems allow us to vividly remember previous experiences. However, recent years have seen accumulating evidence that our memories are not just made for the past. Instead, they also allow us to mentally travel into the future by imagining prospective events. Such imaginings foster more farsighted decisions. They also allow us to learn much the same way that we learn from real experiences.

How does the brain organize our experiences and our knowledge? A possible answer to this fundamental question: our brain’s navigation system forms so-called cognitive spaces in which we arrange our experience along feature dimensions, so that similar experiences are nearby in cognitive space. We propose this based on the combination of a wealth of findings about the functioning of place cells in the hippocampus and grid cells in the entorhinal cortex, which are central to spatial navigation. These cells also map cognitive spaces, thereby providing a spatial framework for human thinking.
