Ipsilateral and contralateral CNIC targeting of LCIC extramodular fields in a P12 GAD67-GFP mouse. Sampling of both the uncrossed (a, b) and crossed (c, d) inputs yields highly periodic signals for each channel. Both projection distributions overlap CR-defined extramodular zones (b, d, blue and red arrows) and are out-of-phase with peak GAD modular labeling (green arrows). Scale bars in (a, c) = 100 μm
