Natural variability in bee brain size and symmetry revealed by micro-CT imaging and deep learning
Fig 6
Variation in brain volume and absolute volume of neuropils (mm3) between honey bee colonies (population A - purple, N = 6 hives; population B - green, N = 3 hives).
(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). Statistical comparisons (p-values) for the neuropil volumes between hives were obtained from the F-test following LMMs and are displayed in bold when significant (see sample sizes in the Methods and statistical details in Table 1).
