| summary | The brain undergoes fundamental changes over the life span, with the most
dramatic changes occurring during infancy and childhood. However, whether these changes
also impact on mechanisms of learning have remained uncertain. Although it is often
assumed that children learn more efficiently than adults, it is unclear, if it is true, which
mechanisms contribute to such greater learning efficiency in children. 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 visual 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 |
