Fig. 9.

Schematic representation of CF and PF wiring onto PC dendrites. CF branches are shown as black lines. Aberrant CF innervation against adjacent PC dendrites is frequent and indicated by asterisks. In particular, aberrant innervation resulting in true dual innervation is indicated byred asterisks. PC spines contacted by CFs and PFs are represented as yellow and red horizontal bars, respectively, whereas free spines are represented aspink horizontal bars. The PCD-I, -II, and -III domains of PC dendrites are dark blue, light blue, and green, respectively. The vertical height of PC dendrites is shown to the left, starting from the initial CF branching point (arrows).
