Simplified diagram illustrating major commissures, tracts, lobes and neuropils in the brain of E. rowelli. Characterised neuropils are depicted in colour; other brain neuropils are indicated in dark grey, cell body rind in light grey. Subregions of largely fused other brain neuropils, including deutocerebral neuropil, not shown. Arrowheads point to microglomeruli.
