title: Automatic morphometric analysis of retrograde changes in the nucleus n. facialis at different ontogenetic stages in the rat.
abstract: The grey level index (= GLI) and the fresh voluem were determined with the image analyser Micro-Videomat for the nucl. n. facialis after axotomy of the left n. facialis. The experiments were performed on 10 rats in different stages of ontogenesis. The GLI is a quantitative parameter which could be quickly obtained and which demonstrated quantitative changes during retrograde reaction in the respective centres. A decrease in the fresh volumes of the affected nucl. n. facialis could also be demonstrated. The meaning of GLI is discussed.
