Since 2009, the association had been campaigning against brain research on rhesus monkeys at four institutes in Tübingen. In 2014, one of them, the Max Planck Institute for Biological Cybernetics, hit the headlines when recordings were published showing severe mistreatment of the monkeys. Doctors Against Animal Experiments filed a criminal complaint with the public prosecutor's office in Tübingen in January 2015. Following those revelations, Marco Wehr accused the association of a lack of proximity to players in medical research and of insufficient expertise in a guest article in the
FAZ in 2017. Among others, he criticized DAAE for campaigning for replacement of animal experiments with cell cultures and computer models, as these could only inadequately reproduce complex biological processes and were therefore, in his opinion, insufficient for researching longer chains of action. In December 2018, Volkart Wildermuth announced in an interview that the trust between the Logothetis working group and the Max Planck Society had permanently been damaged. According to Wildermuth, the MGP had restricted some of
Nikos Logothetis' management functions where animal experiments were concerned. The public prosecutor's office in Tübingen discontinued the proceedings against payment of a fine. In 2022, autopsy reports from the Stuttgart Chemical and Veterinary Investigation Office from 2009 were published. They showed that the skulls of monkeys that had been experimented on in Tübingen had numerous drill holes and a fracture, among other things. A total of six monkey cadavers were delivered from Tübingen, three with and three without heads. According to the autopsy reports, the skull manipulations caused much more suffering to the animals than is legally permitted in animal experiments. ==Eastern Europe Project – Saving Animals with Computers==
