'Comparison to the vertebrate pallium reveals that the annelid mushroom bodies develop from similar molecular coordinates within a conserved overall molecular brain topology and that their development involves conserved patterning mechanisms and produces conserved neuron types that existed already in the proto- stome-deuterostome ancestors. These data indicate deep homology of pallium and mushroom bodies and date back the origin of higher brain centers to prebilaterian times' Prominent lobed neuropils found in annelids and all arthropods except crustaceans. They are thought to be involved in olfactory associative learning and memory[MESH] Mushroom body neuropils are divided into calyces, pedunculus, and its subsequent lobes. In Drosophila these are the alpha, beta, and gamma lobes. GAID:1231 FBbt:00005801 corpora pedunculata
