Exemplary cells of each cell type for all four data sets. Axons are shown in light green, dendrites in dark green. a Mouse retinal bipolar cells (cone-connecting) from Helmstaedter et al. (2013). The dashed line shows the onset of the inner plexiform layer (IPL). The cell types used for analysis are types 1, 2, 3A, 3B, 4, 5I, 5O, 5T, 5X, 6, and 7. Cell types 8 and 9 were excluded from further analysis due to insufficient sample sizes. b Layer 2/3 inhibitory interneurons in primary visual cortex of adult mice (Jiang et al. 2015). BC: basket cells, BPC: bipolar cells, BTC: bitufted cells, ChC: chandelier cells, DBC: double bouquet cells, MC: Martinotti cells, NGC: neurogliaform cells. c Layer 4 inhibitory interneurons in primary visual cortex of adult mice (Scala et al. 2019). LBC: large basket cells, BPC: bipolar cells, DBC: double bouquet cells, HBC: horizontal basket cells, MC: Martinotti cells, NGC: neurogliaform cells, SBC: small basket cells. d Layer 5 inhibitory interneurons in primary visual cortex of adult mice (Jiang et al. 2015). BC: basket cells, DC: deep-projecting cells, HEC: horizontally elongated cells, MC: Martinotti cells, NGC: neurogliaform cells, SC: shrub cells
