Fig. 6. Automatic detection of synaptic contacts.
a, Dorsal view of the vEM dataset, vesicle clouds labeled in blue. b, Close-up examples of automatically segmented vesicle clouds (blue) and synaptic clefts (magenta) in thalamus (Th), pretectum (preT), optic tectum (TeO) and ventral hindbrain (vHb). c. Outline of RGC AFs 4 (left) and 7 (right). d, Volume fraction occupied by vesicle clouds, calculated for all AFs as a percentage of total area volume. Visualization adapted from mapzebrain atlas. Scale bars, 50 µm (a), 500 nm (b) and 10 µm (c).
