People differ significantly in their memory performance. Researchers at the University of Basel have now discovered that certain brain signals are related to these differences.
While it is well known that certain brain regions play a crucial role in memory processes, so far it has not been clear whether these regions exhibit different activities when it comes to storing information in people with better or worse memory performance. Having investigated this matter, a research team led by Professor Dominique de Quervain and Professor Andreas Papassotiropoulos has now published its results in the journalIn the world's largest functional imaging study on memory, they asked nearly 1,500 participants between the ages of 18 and 35 to look at and memorize a total of 72 images. During this process, the researchers recorded the subjects' brain activity using MRI.
The researchers were also able to identify functional networks in the brain that were linked to memory performance. These networks comprise different brain regions that communicate with each other to enable complex processes such as the storage of information."The findings help us to better understand how differences in memory performance occur between one individual and another," said Dr.
According to the researchers, the results are of great importance for future research aimed at linking biological characteristics such as genetic markers to brain signals.The current study forms part of a large-scale research project conducted by the Research Cluster Molecular and Cognitive Neurosciences at the University of Basel's Department of Biomedicine and the University Psychiatric Clinics Basel.
