Figure 4

Complex dendritic spines (thorny excrescences) of CA3 pyramidal neurons. (A) Cajal’s drawing showing pyramidal cells with thorny excrescences in the CA3 (Cajal, 1893). (B–I) photomicrographs of Cajal’s original histological preparations housed at the Cajal Institute. (B) CA3 pyramidal cells of the rabbit stained by the Golgi method. (C–I) Examples of thorny excrescences on CA3 pyramidal neurons. (C–E) Dendrites from a newborn child’s CA3 pyramidal neurons stained by the Golgi method; (F–I) Dendrites of rabbit CA3 pyramidal neurons stained by Kenyon’s variant of the Golgi method. Scale bar: (B) 55 μm; (C–I), 11 μm. Taken from Blazquez-Llorca et al. (2011).
