A. Spike trains of four different neurons from a P8 β2-/-Cx36-/- retina (top), and a P10 β2-/-Cx36-/- retina (bottom). Hexagons to the left of each spike train show the position (filled circle) of the electrode on the multielectrode array that recorded spikes.
B. Fluorescence images of contralateral (left column) and ipsilateral (center column) projections and pseudocolor representation according to the R value for each pixel (third column) in the same LGN slice. Scale bar = 200 μm.
C. Summary of the fraction of pixels with ipsilateral signal alone as a function of contralateral threshold. Error bars = standard error of the mean. Asterisks reflect significance (p<0.05)
D. Summary of the variance of the R-distributions. Error bars = standard error of the mean. N=5 P8 and P14 β2-/-Cx36-/- mice, 3 sections/mouse. Asterisks reflect significance (p<0.05)
