Mauthner Cells (IMAGE) Universität Bayreuth Caption Color-processed microscopic image of a pair of Mauthner cells (green) in a zebrafish. On the left is the head of the fish, on the right the tail. The two green areas on the left are the cell bodies of the Mauthner cells, the structures running to the right are the axons. The image was taken two days after the two axons were severely injured in their middle section, leaving their function significantly damaged. The several smaller branches at the end of the axons demonstrate how axonal regeneration usually occurs. Credit Image: Alexander Hecker.
