Cross Sections of a Mouse Brain (IMAGE) Max-Planck-Gesellschaft Caption To the left several cross sections of a mouse brain are shown. In the dark labeled areas the scientists of the Max Planck Institute were able to selectively eliminate the receptor for a specific neurotrophic factor. In the background neurons that would also die due to Parkinson’s disease, but have been positively affected by GDNF and its receptor, are shown.
