Natural variability in bee brain size and symmetry revealed by micro-CT imaging and deep learning
Fig 7
Variation in brain volume and neuropils volumes (mm3) and correlation between neuropil volumes and total brain volume for bumblebees (N = 77).
(A) Total brain. (B) Antennal lobes (AL). (C) Mushroom bodies (MB). (D) Optic lobes (OL). (E) Medullae (ME). (F) Lobulae (LO). (G) Central complex (CX). (H) Other neuropils (OTH). Boxplots show median volumes (intermediate line) and quartiles (upper and lower lines). Pink triangles display mean volumes. Coloured symbols show the mean of neuropil volumes described for bumblebees in another study using CT scan: Smith et al. [14] (N = 38 bees - blue).
