Purkinje cell growth beyond the twenty-third postnatal day.
Purkinje cell dendritic trees from adult and weanling cerebella were analyzed with an image analysis system following Golgi-Cox impregnation. Measurements of the mean length, number and total length of primary trunks, smooth branches and spiny branchlets were taken to assess the amount of growth between postnatal days 23 and 150. These results revealed a significant post-weanling growth in the length and number of smooth branches and spiny branchlets.
