In a study published in the journal Cell Reports, a team of researchers and clinicians working with Simon Jacob, Professor of Translational Neurotechnology at the Department of Neurosurgery at TUM's university hospital Klinikum rechts der Isar, was able to show how the brain processes numbers. And it happens abstractly, for example when we see the symbol '8' or do complex calculations.
It happens in a very concrete way when we count objects.
