Organisation of mushroom body in E. rowelli. Three-dimensional reconstruction based on anti-acetylated α-tubulin immunolabelling (a) and horizontal optical sections from stacks of confocal micrographs of brains stained against acetylated α-tubulin (b) and synapsin (c). Anterior is up and median is left in all images. a Volume rendering of mushroom body in ventral view. Note connection with central body via ponticulus. b Detail of fascicles of globuli cells with two main branches (dotted line) giving rise to four digitiform branches (arrows). c Detail of the four lobes, all of which are sectioned in inset. Note strongest synapsin immunoreactivity along μ-lobe. ANP, antennal neuropil; CB, central body; δ, dorsal or δ-lobe; FGC, fascicles of globuli cells; λ, lateral or λ-lobe; μ, median or μ-lobe; OLL, olfactory lobe; PED, pedunculus; PNT, ponticulus; v, ventral or v-lobe. Scale bars: 50 μm
