Dendritic Spines and Development: Towards a Unifying Model of Spinogenesis—A Present Day Review of Cajal's Histological Slides and Drawings

Figure 19

The figure shows filopodia, protospines, and dendritic spines of intrinsic neurons of the cerebellar and cerebral cortices, three-dimensional reconstructions, Cajal histological preparations, Golgi-method. (a) Basket cell dendrite, cerebellum, 17-day-old dog. (b) Golgi cell dendrite, cerebellum, 17-day-old dog. (c) Young immature granule cell, cerebellum, newborn cat. (d) Mature granule cell, cerebellum, adult cat. (e) Double bouquet cell, motor cortex, layer III, one-month-old child. (f) Basket cell, motor cerebral cortex, layer IV, one-month-old dog. Filopodia and protospines are color coded in green.
