Properties of horizontal axo-axonic cells in stratum oriens of the hippocampal CA1 area of rats in vitro. Ganter P, Szucs P, Paulsen O, Somogyi P Hippocampus, 2004, 14 (2), pages: 232 - 243 PMID: 15098728; DOI: 10.1002/hipo.10170 |
 "FIGURE 1. Identification of [CA1] horizontal axo-axonic cells {CA1 Horizontal Axo-axonic}. A: Reconstruction of a cell showing dendrites (thick processes) running mainly parallel with the layers in stratum oriens (str. or.) and axonal arbor mostly in the deep pyramidal layer (str. pyr.) and adjacent stratum oriens. Note the characteristic radial axonal terminal segments (arrows) defining it as an axo-axonic cell. Some shrinkage is likely to have occurred during the histological processing, which is apparent from the undulating appearance of the dendrites. B: Reconstruction of the dendritic tree of another cell also shown in C-F. The broken line denotes the compact sublayer of stratum pyramidale, as also seen in the micrograph shown in E. C: Light micrograph of the same cell shown together with a reciprocally connected pyramidal cell (P). The reciprocal connection was evident from the synaptic responses (Figs. 4A and 5)." |

| Notes |
| Axons exclusively target the axon initial segment of CA1 pyramidal cells (and, unlike basket cells, do not target other interneurons) perisomatic axonal targeting interpreted as PCL extended interpretation of SP in apical and basal directions |
