Left, semantic mapping scheme of human brain regions reconstructed. Each brain region is represented by a different color. For each region, the two numbers indicate the number of individual neurons reconstructed and the total reconstruction copies (some neurons were reconstructed more than once for validation), respectively. Right, representative cells for different brain regions are displayed in each row. From left to right, each column gives the images (scale bar, 50 m), user participation (each color corresponds to the annotation of an individual user), user attention heatmaps (color indicates the number of editing users for the region), local structural complexity (color indicates the complexity of the local structure), imaging signal complexity (intensity indicates signal complexity in the local region) and the actual locations where brain tissues were extracted, each represented by a different color. These extracted regions were then mapped and overlaid onto the standard brain coordinate template MNI152. Box plots on the left depict the relationship between reconstruction time and accuracy for various collaboration patterns across all neurons. The mean for each group is indicated by numbers in white. Medians are marked with a central black line. Each box represents the interquartile range, spanning from the 25th percentile to the 75th percentile of the data distribution for each group. Whiskers extend to the furthest points within 1.5 times the interquartile range from both the lower and upper quartiles. The data encompass results from three independent experiments with sample sizes n = 13 for two collaborators, n = 17 for three collaborators and n = 15 for four collaborators. FL, frontal lobe; IFG, inferior frontal gyrus; IPL, inferior parietal lobule; MFG, middle frontal gyrus; MTG, middle temporal gyrus; OL, occipital lobe; PL, parietal lobe; SFG, superior frontal gyrus; S(M,I)FG, an intermediate region bordering the SFG, the MFG and the IFG; STG, superior temporal gyrus; TP, temporal pole.
