A GABAergic interneuron that selectively innervates the axon initial segment of pyramidal cells. Their local axonal clusters are formed by high-frequency branching at shallow angles, often ramifying around, above or below their somata with a high bouton density. The characteristic terminal portions of the axon form short vertical rows of boutons, resembling the candlesticks and candles of a chandelier. Chandelier cells can be multipolar or bitufted.
