Comparison of the intra- (, degree of bundling) and inter-PN (, degree of packing) distances of -th homotype in AL, MB calyx, and LH (from lighter to darker colors) from (A) the FAFB dataset …
The degree of overlapping () for -th homotype in AL, MB calyx, and LH (from lighter to darker colors) calculated from the uPNs based on (A) the FAFB dataset and (B) the hemibrain dataset. The …
The color code is the same as in Figure 6. The blue lines in (A) and (B) denote .
Scatter plots depicting the relationships between s at two different neuropils calculated from the uPNs based on the hemibrain dataset; (A) AL versus MB calyx, (B) AL versus LH, and (C) LH versus …
Asterisks (*) mark homotypes composed of a single uPN while plus (+) mark homotypes composed of a single uPN under our selection criterion but are actually a multi-uPN homotype, whose intra-homotype …
A diagram summarizing how the clusters of uPNs in MB calyx (14 clusters) and LH (13 clusters) from the hemibrain dataset are associated with the odor types (Dark green: decaying fruit, olive: …
(A) The connectivity matrix , where when any uPNs in the -th homotype and -th third-order neuron synapses and otherwise. (B) The number of -th homotype-specific connections () and …
The and synaptic connectivity matrices for the synaptic interface between PNs and KCs () (left) and between PNs and LHNs () (right). Homotypic uPNs are merged together.
Bar graphs depicting the number of KCs/LHNs that synapse with a specific homotype (, blue) and the percentage of KCs/LHNs that synapse with a specific homotype (, red) at (A) PN-KC and (B) …
The color code represents , which is the number of the third-order neurons (KCs or LHNs) synapsing with both homotypes and . The black color is used when there is no third-order …
The total number of third-order neurons connected to each homotype, which corresponds to the diagonal element of common synapse matrix () in MB calyx (top) and LH (bottom). Figure 11—figure …
The black colour is when there is no third-order neuron-mediated signal integration () between two homotypes X and Y.
The same uPNs in the two tree structures are connected with lines, which visualize where the uPNs clustered by one method end up in the clustering results of another. The labels for uPNs are …
The data points from skeletal reconstruction are projected to each axis to generate distributions from which local minima are obtained. The process is repeated while rotating the uPNs along each …
