Welcome to the homepage of the Emmy Noether Group

We are psychologists and cognitive neuroscientists trying to understand how and why mechanisms of learning and brain plasticity change over the lifespan.

It is often assumed that children learn more efficiently than adults, although the neuronal mechanisms responsible for such increased learning efficiency in children have remained unclear. In this study we examined visual learning in elementary school age children and adults using functional magnetic resonance spectroscopy to measure inhibitory, GABAergic processing during and after visual learning in vivo. We found that visual learning triggered an increase of GABA only in children that persisted for several minutes after training ended. This novel finding predicted that training on new items rapidly increases the concentration of GABA in children and allows the learning to be rapidly stabilized. In subsequent behavioral experiments, we found that children indeed stabilized new learning much more rapidly than adults, which agrees with the common belief that children outperform adults in their learning abilities. Our results therefore point to GABA as a key player involved in efficient learning in children.

In this study we investigated neuronal mechanisms involved in skill learning. Skill learning (for example, learning to ride a bicycle) facilitates our interactions with the environment. However, it is effortful to acquire a new skill, begging the question whether the brain has evolved mechanisms to support such learning. Here, we used a combination of behavioral training and functional MRI to examine tactile skill learning with different body parts (hand and foot). We found that this learning was strongly supported by coactivation of cortical territory in somatosensory cortex representing untrained body parts. Our results indicate that cortical coactivation could not only serve as a neuronal support mechanism for skill learning with the trained body part, but could also lead to the acquisition of the new skill with the untrained but coactivated body part.
