Mushroom bodies are prominent neuropils found in annelids and all arthropod groups except crustaceans. First explicitly identified 1850, the mushroom differ size complexity between taxa, as well different castes of a single species social insect. These differences led some early biologists to suggest that endow an with intelligence or ability execute voluntary actions, opposed innate behaviors. Recent physiological studies mutant analyses have divergent interpretations. One interpretation is conditionally relay higher protocerebral centers information about sensory stimuli context which they occur. Another play central role learning memory. Anatomical predominately associated olfactory pathways phylogenetically basal insects. The input body calyces more recent insect orders acquired character. An overview history research on bodies, comparative evolutionary considerations, provides conceptual framework for discussing roles these neuropils.
