## Chapter 9/Figure 5.jpg Back | Home | Next | (A) Mean orientation of dendritic branches. The initial segments of dendrites are represented by dots. The outlines of the anterior commissure (ac) are indicated by small dots. (B) Differential density scatter plot of the same database. Dots represent cholinergic cells (n= 15,700), filled circles mark the high density locations where the density of cells is greater than 20 per unit space (250 x 250 x 100 microns). Flakes are due to the section steps along the z axis. Cells and their dendrites were mapped from 34 consecutive horizontal sections stained for choline acetyl- transferase. The comparison of (A) and (B) suggests the iso-orientation of dendrites in the high density cell cluster.
