Figure 1

Reconstruction of iCRs and examples of their ultrastructure. (a–d) show reconstructions of the soma and dendritic trees (black) as well as the axonal arbor (red) for 4 of the 5 cells recovered from whole-cell recordings in slices from CR::GFP mice. (e–g) Examples of the appearance of the cell shown in (d) as seen with the electron microscope. (e,f) show axonal boutons belonging to this cell forming axoaxonic synapses onto the central terminals of type I glomeruli (CI). In (g), part of a dendrite of this cell is postsynaptic to another type I central glomerular bouton (arrowhead). Scale bars = 100 μm (a–d) and 0.5 μm (e–g).
