Figure 4

The graphical presentation of age-related changes in previously well-known quantified parameters, (a,c) number of nerve fibers (Qty), and (b,d) nodes. (a,b) Each color in 2-D color maps reflected the degree of quantified results regarding higher values as bright yellow to lower one to dark blue. (a,b) The quantified results are presented as 3-D bar graphs, while the height of the bar shows the degree of parameters in each volume.
