Fig. 3.

Reconstruction of biocytin-injected chandelier cells and the pyramidal neurons inside their axonal arborizations. Two semi-thin sections of ChC2 before (a, d) and after staining with toluidine blue (b, e). c, f Same semi-thin sections as in b and e, respectively, with the chandelier soma and processes colored in red, the pyramidal cells innervated by a chandelier cell cartridge colored in green and the remaining (non-innervated) cells inside the axonal arbor of the chandelier cell colored in blue. The border of the axonal arbor of the chandelier cell in each semi-thin section is indicated in yellow. Scale bar (in f), a–f 90 µm
