Morphology of cells filled with Alexa Fluor-594. A, Examples of +/+ (left) and du^2J/du^2J (right) PCs filled with Alexa 594 during whole-cell recording. Scale bar, 50 μm. B, Bar chart quantifying the number of branch points for the longest dendrite for +/+ (n = 6; □) and for du^2J/du^2J (n = 5; ■). C, Bar chart showing the area occupied by the dendrites, quantified by forming a polygon of the dendritic tips, for +/+ (n = 6; □) and for du^2J/du^2J (n = 6; ■). *p < 0.05 (Student's nonpaired t test).
