Structure of the honeybee brain and mushroom bodies. a Schematic drawing of the honeybee brain. MB, mushroom body; OL, optic lobe; AL, antennal lobe. b Hematoxylin-eosin staining of the left MB, which corresponds to the region indicated by a square in panel (a). Each MB has two cup-like structures: lateral and medial calyces, each of which comprises calyces and a pedunculus. lKC and sKC, large- and small-type Kenyon cells, respectively. c The honeybee MB calyces are subdivided into three layers: lips, collars, and basal rings. Original figure (photo for the hematoxylin-eosin staining of the left MB) from [20] was modified and used for panels (b) and (c)
