|Abstract:"Serial electron microscopy and 3-D reconstructions of dendritic spines from hippocampal area CA 1 dendrites were obtained to evaluate 2 questions about relationships between spine geometry and synaptic efficacy."
|p.2983 right column bottom paragraph:"Seven dendritic segments located approximately 200-250µm from the pyramidal cell layer in stratum radiatum were reconstructed through serial sections. The complete 3-D reconstructions
of these dendritic segments are illustrated in Figure 1, where the individual dendtitic spines are black thick lines and their dendritic shafts are thinner gray lines. These dendritic segments ranged in length from 5.9 to 12.4µm (Table 1). Their diameters were measured at the base of each dendritic spine and ranged between 0.32 and 0.85µm (Table 1). The total dendritic volumes and surface areas were computed by closing the holes left at the origins of each of the edited spines." See notes beneath table
