Examples of autaptic junctions established by the DTCs shown in Figure 5. A, B, Autapses on the DTC of Figure 5A. A, An autaptic terminal (a 15, 16,17) targeting the soma (s) established three separate autaptic junctions, two of which (underlined numbers) are illustrated here.B, A bouton (a2) of the DTC forms an autapse on the dendrite of the cell. C, One (underlined number) of the two autapses established by a terminal (a 6,7) of the DTC shown in Figure 5B. A synapse (between arrowheads) formed by an unlabeled bouton (t) and the dendrite (d) of the DTC are indicated. Numberingis identical to Figure 5. Autaptic clefts are indicated betweenarrows.
