PSD-95 in the retinal IPL of visually naïve and experienced larvae from 5 to 7 dpf. (a) Example confocal images of 7 dpf retinae stained with DAPI (blue) and PSD-95 (green) in naïve (top row), 2-session static experienced (middle row) and 2-session moving experienced (bottom row) larvae. The larger scale bar (bottom right) represents 50 µm. Example cropped images for puncta analysis are also shown in the middle column, with the smaller scale bar representing 5 µm. Sections show the ganglion cell layer (GCL), inner nuclear layer (INL), inner plexiform layer (IPL), and outer plexiform layer (OPL). (b) Violin plots of PSD-95 density in 5 to 7 dpf visually naïve and experienced larvae. Points are individual retinae, white lines represent medians and dark bands indicate the inter-quartile range. Bayes Factors (BF) >3, considered as evidence in favour of a difference between groups, are shown.
