Morphological features of the PSD95-GFP expressed mouse ganglion cells chosen for analysis.

Stratification level in the IPL: percent depth from the inner nuclear layer to the ganglion cell layer.
Dendritic arbor density: total dendritic length/dendritic field area.
Asymmetry index: (dendritic length difference between 1st and 3rd quarters + dendritic length difference between of 2nd and 4th quarters)/total dendritic length.
Linear puncta density: total puncta number/total dendritic length.
Values are mean±SEM.
This classification scheme of mouse ganglion cells is based on Völgyi et al., 2009, and is equivalent to (I) Sun et al., 2002; (II) Badea and Nathans, 2004; (III) Kong et al., 2005; (IV) Coombs et al., 2006.
