Spike count correlations sorted by neurons' visuospatial tuning preferences.

<p>Like <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061503#pone-0061503-g003" target="_blank"><b>Figure 3</b></a>, correlations are visualized on the MEA. Each square represents an electrode, and lines between the electrodes represent correlations between neurons recorded on those electrodes. The thickness of the line is proportional to the magnitude of the correlation (from 0.055 to 0.55) and the color represents the sign (brown = negative, green = positive). The large panels represent <i>r_sc</i> and the small panels <i>r_sc,p</i>. The row displays data from <b>A</b>) tuned-tuned, <b>B</b>) tuned-untuned, and <b>C</b>) untuned-untuned pairs. The column displays data from <b>A</b>) all tuned pairs, <b>D</b>) tuned pairs with RFs separated by less than or 90°, and <b>E</b>) RFs separated by more than 90° (bottom). <b>F</b>) The bar graph displays the proportion of significant correlations for all the tuned-tuned pairs (see legend).
