Figure 11.
Number of synapses formed by the different cell types with an individual neuron. A, Each total bar indicates the number of synapses formed with a neuron of a given cell type (indicated along the x-axis). The width of each color-coded subdivision of the bar indicates the total number of synapses that a particular presynaptic cell type forms with the neurons. The correspondence between the colors and the presynaptic cell types is indicated. B, Histogram of synapses formed by the different cell types with an individual neuron, as shown in A. For visibility, projections forming < 1000 synapses are shown only. Gray bars indicate the histogram of asymmetric synapses. Bin size is 50 synapses. Inset shows the histogram of synapses formed by all projections (log-log scale). C, For each postsynaptic cell type (x-axis), the three largest proportions of synapses of its dendritic trees that were formed by the different cell types are shown (closed circles). Also shown for each cell type is the proportion of unassigned synapses on its dendritic trees (open circles).
