Fig. 5From: Stimulation induces gradual increases in the thickness and curvature of postsynaptic density of hippocampal CA1 neurons in slice culturesHistograms of thickness of PSD from exp. 5 in Additional file 1. Experimental conditions and average thickness of PSD are listed on the upper right corner of each panel. Both the range and mean values of average thickness of PSD gradually increased with NMDA treatment time. Statistical analyses are listed in footnotes of Additional file 1Back to article page
