"Figure 1. Two morphologically and physiologically contrasting DG-SOMI types. É (C) Reconstructions of two representative intracellularly labeled DG-SOMI types. Somata and dendrites are depicted in black and axons in red. Grey lines depict layer-specific borders. From left to right, hilar perforant path- associated interneuron (HIPP), hilus-associated interneuron (HIL) {DG Hilus-Associated Interneuron*}. "
