Qualitative Neuronal Inspection. The figure shows eight panels (A-H) rendering cells from the Duke-Southampton archive and the Gulyás repository (see Results and Discussion). Each panel presents one plotted cell seen from two different viewpoints. Top panels correspond to the 'xy' viewpoint and bottom panels to the 'yz' viewpoint (i.e. 90° rotation). Cells belonging to the Duke-Southampton archive have a similar z-axis noise
. Cell smoothing successfully abolishes z-noise (compare B vs. C, 'yz' viewpoint). Calibration bars 100 μm.
