Chandelier cell and its processes. (A) High power micrograph of the soma and proximal processes of a chandelier cell. (B) Fifteen-exposure photomontage of a specific terminal portion of a chandelier cell expanding toward the soma (arrow) to build-up a pericellular nest. (C) Camera lucida drawing depicting distal dendrites of a pyramidal (left) and a chandelier cell (dashed). Note that primary olfactory axons interact with the chandelier cell dendrites by means of boutons en passage (hollow arrow) and descending collaterals (black arrows). (D) Twenty-nine-micrograph photomontage of layer I. Two putative synapses of passage (arrows) with distal dendrites of a chandelier cell. Rapid-Golgi technique, adult mouse brain. Scale bar = 10 μm in (A–C); 15 μm in (D).
