Densities and ratios of GABAergic to glutamatergic postsynaptic sites of three types of RGCs across development.

<p>Linear densities (left axis) and ratio (right axis) of PSD95CFP (white bars) and YFPγ2 puncta (gray bars) on P12 and P21 ON-S A-type cells (<b>A</b>), OFF-S A-type (<b>B</b>) and bistratified DS (<b>C</b>) RGCs. Lines link data points from the same cell. Statistical tests between ages were two sample student's t-test unequal variance, and within ages were two sample paired student's t-test. *** = P<0.001, ** = P<0.01, * = P<0.05.
