Pair of structures in the brains of some arthropods and annelids
Mushroom bodies visible in a Drosophila brain as two stalks. From Jenett et al., 2006[ 1]
The mushroom bodies or corpora pedunculata are a pair of structures in the brain of arthropods , including insects and crustaceans ,[ 2] and some annelids (notably the ragworm Platynereis dumerilii ).[ 3] They are known to play a role in olfactory learning and memory . In most insects, the mushroom bodies and the lateral horn are the two higher brain regions that receive olfactory information from the antennal lobe via projection neurons.[ 4] They were first identified and described by French biologist Félix Dujardin in 1850.[ 5] [ 6]
