Likewise in the cat, after stimulation for several hours,the nuclei of the ganglion-cells, which previously were vesicularand round, are shrunken and have an irregular contour, while thearrangement of the contents has changed materially (Fig. 240).According to Mann, and also Lugaro, the change of the ganglion-cell during its activity consists essentially in a turgescence of thepro
