LG cells receive axosomatic excitatory inputs from bilateral SOC. After an injection of palGFP Sindbis virus in the hemilateral SOC, LG cells (blue, asterisks) with GFP+ (red) terminals, which were also positive for VGLUT2 (green), were found in the ipsilateral (A, B) and contralateral (C, D) IC. Case 10-60. (B, D) High-magnification images of a box in A₁ and C₁ with orthogonal views of the stack cut at 3 planes parallel to xy- (blue lines), yz- (a red line), and xz-planes (a green line). GFP+/VGLUT2+ terminals made contact on LG cells (arrows). Scale bars: 10 μm (A, C), and 1 μm (B, D). Three-dimensional reconstructions of these GFP+ axons and LG cell bodies are shown in Fig. 5.
