In the SFB 1280 great potentials gather together. The scientists, from the professors to the doctoral students, offer very selected skills. However, accumulated knowledge alone does not solve set tasks. The individual contributions to our collaborations lead to the joint responsibility. The common basis for working together are the tasks that share the goals and questions of the SFB 1280. Every member working on these result in the constant development of the SFB 1280 regarding the puzzle of extinction learning.
