Statistical analysis of co-fasciculation with the cholinergic matrix. The co-fasciculation between the two sets of processes was measured in the original confocal image for comparison with images were one label was rotated by 90 deg, 180 deg, or 270 deg to estimate the number of overlapping pixels expected by chance. Only co-fasciculation between the dendrites of ON/OFF DS cells and the cholinergic matrix occurred more frequently than expected due to chance. Thus, the original orientation was the same height for A, OFF α ganglion cells and B, ON α ganglion cells. In contrast, the peak height for both OFF (C) and ON (D) strata for ON/OFF DS ganglion cells was approximately twice as high as the controls. This is the signature of co-fasciculation as opposed to chance overlap.
