title: [Current state of the scientific activity of the Aachen group concerning number processing].
abstract: BACKGROUND
  The research group from Willmes and colleagues is one of the most advanced research groups in cognitive neuroscience. The use and nature of the numeric magnitude representation constitutes one of the study objects of the mentioned research group. This mental representation provokes a great controversy among the members of the scientific community studying number processing and arithmetic. As a consequence, there are several different theoretical models concerning number processing. In this work, we have reviewed some of the scientific studies realized by the Aachen group concerning number processing, with the aim to expound the current state of its activity.
  
  
  METHODS
  In the works from Willmes and colleagues, we can notice a logic sequence, regarding the formulation of work hypothesis. The course of evolution of their activity starts studying number processing and arithmetic on German listener population and continues with a progressive integration of the German deaf population into their work. There is, as well, an emergent trend in this group to research number processing at the classroom. This means to examine the underlying mental representations in the education field.
  
  
  CONCLUSIONS
  The information included in the studies analyzed here, leads to several scientific questions which need to be researched in future studies, and questions and complements what has been supported by other research groups.
