Ivy/neurogliaform interneurons coordinate activity in the neurogenic niche. Markwardt SJ, Dieni CV, Wadiche JI, Overstreet-Wadiche L Nat Neurosci, 2011 Nov, 14 (11), pages: 1407 - 1409 PMID: 21983681; DOI: 10.1038/nn.2935

"Supplemental Figure 3. Non-Ivy/NGs[neurogliaform] {DG MOCAP} [in the dentate gyrus] presynaptic to NGCs [newborn granule cells]. a, ... Right, reconstruction of this presynaptic interneuron. Arrowheads point to NGC (green) and presynaptic interneuron (red dendrites and gray axon). The interneuron had 4 primary aspinous dendrites, 3 of which were contained in the inner molecular layer and granule cell layer, the other extended into the hilus. The axon covered the granule cell layer and the inner molecular layer, with a less dense portion extending into the hilus. The mean interbouton distance was 7.1 [micro]m, the total axon length was 15,750 [micro]m, and the total dendrite length was 1,108 [micro]m. The location of this NGC soma was atypically close to the inner molecular layer."
