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

Figure 10

(a) Shows Purkinje cell forming the dendritic branchlets, Cajal histological preparation, Golgi method, newborn cat. Insets: 1, terminal filopodia; 2, thin dendritic spines; and 3, dendritic spines contacting climbing fibers. (b) Purkinje cell, 15-day-old cat. Insets show filopodia and thin dendritic spines, Cajal scientific drawing [23, Figure 2]. (c) Purkinje cell, apical branch, three-dimensional reconstruction showing dendritic filopodia and protospines (green) and few dendritic spines (red), newborn cat. (d) Purkinje cell, dendritic filopodia, protospines and dendritic spines, rat of 5 days (A), 10 days (B), 15 days (C), and 30 days (D); scientific drawing of Berry and Bradley [24].
