[Automatic pictorial analysis of normal and experimentally altered nervous tissue]

1. Structural changes of the dorsal LGN of the albino rat following unilateral enucleation cause its decrease of volume. 2. Using the Quantimet 720 M and Nissl stained preparations we tried to explain the decreased volume by estimation of three parameters: The whole area of the cells, the number of neurons and the size distribution of cells. 3. The whole area and the number of neurons are constant. 4. The size distribution of cells changes significantly and indicates an alteration of the tissue surrounding the cells (development of the neuropil, loss of fibers). 5. The changes of the maxima of size distributions following enucleation suggest a diminution of the area of neuron somata, but are not significant. 6. Using more exact methods of measurements we want to get more detailed results.
